4. Function Parameter Table and Parameter Descriptions
4.1 Parameter Table (see parameter overview)
4.2 Parameter Descriptions
4.2.1 F03: Basic torque frequency for opening the door. The larger this value, the smaller the torque, and vice versa.
4.2.2 F04: Low-frequency torque compensation for opening the door. The larger this value, the greater the torque.
4.2.3 F05, F06: F05 is the self-learning acceleration time, F06 is the self-learning deceleration time. Adjusting these parameters can facilitate smooth self-learning.
4.2.4 F08: Reverse deceleration time. Adjusting this parameter can ensure a smooth operating curve when encountering light curtains and torque monitoring.
4.2.5 F09, F10: Normal acceleration and deceleration times. Adjusting these parameters can ensure a smooth operating curve during normal operation of the door.
4.2.6 F11: Control mode. F11=0 is panel control mode; F11=1 is manual mode; F11=2 is normal mode (terminal control mode). For versions above H100 (including H100), the panel control mode and terminal control mode are set by the automatic/manual switch on the housing: switch to manual for panel control, switch to automatic for terminal control.
4.2.7 F14: Door width correction. This parameter is mainly set to eliminate pulse errors caused by encoder errors, mechanical errors, etc., during self-learning.
4.2.8 F19: Carrier frequency. The higher this parameter is set, the less noise the motor makes, but the heat generated by the inverter increases, and the maximum output power decreases; the lower this parameter is set, the more noise the motor makes, and the inverter is less likely to heat up.
4.2.9 F20: Data protection. Various parameter modifications must be made under a specific parameter; otherwise, they cannot be modified. This parameter is set to 279.
4.2.10 F24: Torque monitoring. When the car door is closing, if there is a reverse torque applied that exceeds the maximum allowable closing torque within a specific range (8%~80% of the door width), the car door will stop closing and automatically open. After the door is fully open, it will automatically close again. F24=0 means torque monitoring is disabled; F24=1 means torque monitoring is enabled.
5. Inverter Debugging and Operation
5.1 Wiring Diagram (see Appendix 1) Check if the terminal wiring is correct.
5.2 Encoder Installation Wiring
5.2.1 The installation of the through-type encoder must meet the following requirements: The encoder has 4 wires defined as: Brown: DC12V, White: 0V, Yellow: A pulse, Green: B pulse. For encoder installation, follow the wiring diagram shown above.
5.3 B type, B-C type, B-D type inverters self-learning start.
5.3.1 After completing the above work, power on for self-learning. After powering on, the digital display shows HdXX (for example, showing Hd47 for version 47 software) as the software version number, then flashes to display 20.00 (20.00 represents the inverter can read 20000 pulses). At this time, all LEDs on the panel are off. The flashing displayed value is the readable pulse, and the inverter is powered off.
5.3.2 Place the door in the middle position, neither fully open nor fully closed, then power on the inverter. After the inverter flashes the displayed value, pull the door towards the closing direction. During this pulling process, the value should continuously decrease. Then push the door towards the opening direction. During this pushing process, the value should continuously increase. If the closing direction value increases and the opening direction value decreases, it indicates that the encoder A and B pulses are incorrectly connected to the inverter; swap the connections of A and B. Self-learning should be initiated in panel control mode, i.e., F11=0 and F56=0. Check if F11 is set to “0”. The method is as follows: In the door machine stop state, press the function key to switch the display from parameter value to parameter unit, i.e., display F00. Use the increment or decrement keys to adjust the display to F11, then press the function key to display “0” or “1”, “2”. If it is “0”, no changes are needed. If it is “1” or “2”, use the decrement key to adjust the value to “0”, then press the “Write” WR key to save the modified parameters. The adjustment for parameter F56 is similar, and will not be elaborated here.
5.3.3 For software versions before 47 (including version 47), self-learning is as follows: First, issue a close door command. After the inverter receives the command, it will close the door slowly, and the digital display will gradually decrease until the door is fully closed, at which point the display will show “0”. Then issue an open door command. After the inverter receives the open door command, it will open the door slowly until fully open, and the digital display will show the maximum door width pulse count, then switch to display 100% (we define fully closed as “0” and fully open as “100%”) to indicate the end of self-learning, automatically entering normal mode. At this point, the learning result can be stored in the inverter by setting F56 to “2”. If there is a power outage, it will not relearn, but when changing parameters, special attention must be paid to ensure that DO and DC are off. After learning is complete, press the stop key to turn off the DO and DC lights. If you want to relearn, F56 must be set to “0”, then press and hold the stop key, and then press the compel close key to reset the inverter, allowing for re-learning.
5.4 Parameter Adjustment for B type, B-C type, B-D type inverters.
5.4.1 Adjustments for the opening state of B type inverters.
3.1.2 The door machine inverter is installed on the top of the car, ensuring easy observation of the inverter’s working status and cleanliness, with good heat dissipation space.
3.2 Terminal diagrams and descriptions.
3.2.1 B type inverter terminal diagram without aviation plug.
From the door opening operation curve, it can be seen that from F25 to F28, there are four speed change points corresponding to speeds from F33 to F36. Changing F33 can change the initial speed of opening the door, changing F34 can change the running speed of opening the door, and changing F35 and F36 can change the final speed of opening the door. The larger the values of F33 to F36, the faster the speed, and vice versa.
From the door closing operation curve, it can be seen that from F29 to F32, there are four speed change points corresponding to speeds from F37 to F40. Changing F37 can change the initial speed of closing the door; changing F38 can change the running speed of closing the door; changing F39 and F40 can change the final speed of closing the door. The larger the values of F37 to F40, the faster the speed, and vice versa.
For changing F25 to F28, it can change the door opening speed change point position; the smaller the value, the earlier the speed change, and vice versa.
For changing F29 to F32, it can change the door closing speed change point position; the larger the value, the earlier the speed change, and vice versa.
5.4.2 Self-learning state adjustment.
F46 is the self-learning normal speed; the larger the value, the faster the self-learning operation speed, and vice versa.
F49 is the self-learning torque frequency; the larger the value, the smaller the torque during self-learning, and vice versa.
5.4.3 B-C type inverter door opening command code description.
Note: “×” – any state, can be either 1 or 0.
5.4.4 Debugging methods for B-D type inverters.
The panel operation method is the same as that for B type door machine inverters, and will not be elaborated here. The automatic control mode only requires setting F11 to 2 to achieve serial port control for opening and closing the door or inserting TT into the serial port to operate the door machine. The control cabinet parameter for the door machine type needs to be set to “0”.
6. Fault Identification and Elimination
After powering on the door machine controller, it will briefly display the software version number, for example, displaying “Hd29”, indicating that the software version is the 29th version. If there is a problem with the door machine controller, please inform the supplier of the software version number.
6.1 No display on the panel digital tube.
6.1.1 Check if the power supply AC220V is applied to PH and N terminals. Use a digital multimeter in AC mode, with the red and black probes connected to the inverter PH and N terminals. The multimeter should display AC220V ± 10%.
6.1.2 After checking the above parts, check if the fuse is intact.
6.1.3 If the above checks are normal, it indicates that the inverter has a problem.
6.2 The door movement direction is inconsistent with the open/close command.
6.2.1 Check the control line connections, which can be observed from the panel DO and DC indicator lights.
6.2.2 If the above connections are correct, adjust the phase sequence of the motor connections.
6.3 During the self-learning process, the display jumps from “0” to “100%” with a relay sound during the door operation.
6.3.1 After powering on the door machine inverter, place the door in the middle position, then pull the door towards the closing direction. The digital value should continuously decrease, and when pushing the door towards the opening direction, the digital value should continuously increase. If the situation is reversed, swap the connections of encoder A and B.
6.3.2 If the digital value does not change during the door operation, check the alignment between the encoder and the code disk, ensuring that the encoder is perpendicular to the axis of the code disk, and that the encoder slot is inserted into the disk by a bit more, ensuring a gap of 1mm – 2mm between the edge of the code disk and the encoder groove.
• Measure the encoder power supply with a digital multimeter to see if it is above 15V, with a minimum of 14V. If there is no voltage, it indicates a fault in the inverter. If there is voltage, push and pull the door, measuring the encoder A and B pulse outputs with the black probe connected to OV and the red probe connected to A and B respectively. Check for high and low level changes. If there are no changes, it indicates a problem with the encoder, and the encoder should be replaced.
• 4. If the door does not fully open during the learning process. The self-learning torque is too small; adjust F49 to decrease the value and increase the torque. Adjust F46 to increase the push speed, making it faster.
• 5. If there is a loud noise when the door fully opens during the learning process. The self-learning torque is too large; adjust F49 to increase the value and decrease the torque. Adjust F46 to decrease the push speed, making it slower.
• 6. Unable to self-learn normally.
During the self-learning process, before the door is fully open, check if F56 is set to “0”. If it is set to “1”, it should be changed to “0”.
• 7. If the door hits the end when fully open or closed.
• 7.1 Carefully observe whether the digital tube display changes continuously during the opening and closing process, and check for any loss of code. If there is a loss of code, check the installation position of the encoder and the code disk, and whether the teeth of the code disk are bent. Adjust the position if incorrect, and straighten the bent teeth of the code disk.
• 7.2 If the basic torque is too large or the speed change position is incorrect.
• Adjust F03 for opening the door and F27 for closing the door. Increase the value of F03 and decrease the value of F27.
• 7.3 If the door hits during closing, adjust F52 and F31, increasing F52 and decreasing F31.
• 8. If the door operation maintains a low speed without speed changes, it indicates an encoder fault.
• 9. If the display shows “OC”.
• 1. Check if there is a short circuit in the inverter output or if the motor wiring is incorrect.
6.9.2 Check if the door opening and closing control lines share the same cable with high voltage. If so, they must be separated.
6.9.3 Inverter fault.
6.10 If the manual door opening works normally, but when switching to control cabinet control mode, the door does not open or close at the floor level.
6.10.1 Check if the inverter control mode is set correctly, i.e., F11=2. If F11 ≠ 2, set F11=2.
6.10.2 In the case of F11=2, use a jumper wire to directly short the inverter terminals to replace the open/close door signal, i.e., short terminal 4 to terminal 11 for opening the door, and short terminal 5 to terminal 11 for closing the door. Check if the inverter operates normally. If it does, it indicates that the inverter is not faulty; if not, it indicates a fault in the inverter.
6.10.3 If the inverter operates normally, it verifies that the door machine is not faulty, and external wiring should be checked. The method of operation is as follows:
A. Check if the control cabinet DO and DC relays are working normally.
B. Check if the DO and DC signals are reaching the door machine inverter terminals.
• Check if the contact resistance of the DO and DC relays is too high (the value should be less than 0.1 Ω).
6.11 Sometimes the door does not close, or the door opens again after closing to the middle position.
6.11.1 Check if the light curtain has interference. Check for resistance and torque monitoring.
6.11.2 Check if the DC relay is reliably engaged. The method of judgment is as follows: Use a digital multimeter in DC voltage mode, with the red probe on terminal 5 of the inverter and the black probe on terminal 11. During the closing of the door, the DC relay should always engage, and the voltage between terminals 5 and 11 should be “0” V. If there is voltage, it indicates that the DC relay may not work reliably at times, or there is a poor connection in the cable, and the DC relay should be replaced or the poor connection in the cable should be found.
6.12 The door open/close signal does not reach the control cabinet.
Determine whether the door open/close signal is not sent by the door machine inverter or not received by the control cabinet. The method is as follows:
Use a digital multimeter in buzzer mode, remove the plugs from terminals 18, 19, 13, and 12 of the inverter, and place the red and black probes on terminals 12 and 13 respectively. When the door is closed, terminals 12 and 13 should be connected, and when the door is fully open, terminals 12 and 13 should be disconnected. Similarly, place the red and black probes on terminals 18 and 19 respectively. When the door is open, terminals 18 and 19 should be connected, and when the door is fully closed, terminals 18 and 19 should be disconnected. If the measured results are the same as above, it indicates that the door machine inverter is not faulty, and the wiring between the control cabinet and the door machine inverter should be checked.
6.13 Troubleshooting for synchronous belt-driven door machines.
6.13.1 Fault phenomenon: The door does not close after reaching the floor level to let people out, and does not move the car.
6.13.2 Fault cause: Mechanical adjustment is not in place, causing the synchronous belt to skip teeth and lose code.
6.13.3 Solution: First, adjust the mechanical position so that the door should always keep the passive wheel, active wheel, and synchronous belt in parallel during operation. The door leaf should be in several parallel planes.
• The synchronous belt should be tight enough; when pressed by hand, it should feel strong, and ensure smooth operation of the door.
• Set the F14 parameter to 30.
6.14 Fault phenomenon: Sometimes during the opening and closing process, it displays DCB, then freezes, and after power off and on, it works normally, but after a period of time, the above phenomenon occurs again.
Fault cause: Incorrect parameter adjustment.
Solution: Set F12 to 0, selecting the free stop mode.
6.15 Fault phenomenon: During the closing process, the light curtain or small leaf continues to operate, then hits the door.
Fault cause: Incorrect parameter adjustment.
Solution: Adjust F08 and F09 parameters to 4 or 6, reducing normal acceleration and reverse acceleration times.
6.16 Fault phenomenon: The door does not close after reaching 10% position, and the door machine inverter sends out the door close signal.
Fault cause: Incorrect parameter adjustment.
Solution: Adjust F31 to be as small as possible to avoid hitting the door when closing, and set F54 to less than 5% or smaller.
