Tips: Variable Frequency Drive Overvoltage
Overvoltage alarm is generally present at downtime, the main reason is that the deceleration time is too short or the braking resistor and the braking unit are problematic. For example, a 5hp VFD displays "OU" when shutdown. Before repairing the VFD, should make sure the reason for "OU" alarm is what. Here is because during the VFD deceleration, the speed of the motor rotor winding cutting the rotation magnetic field becomes fast, the rotor electromotive force and current increases, so that the motor is in power generation state. The feedback energy flows to DC part through the diode, which connects in parallel with high-power switch tube in inverting part, and finally causes by DC bus voltage increase. So, should focus on checking the brake circuit. After measuring the discharge resistance, find there's no problem. In the measurement of the brake tube find it breakdown. Replace it and power on, even fast parking have no problem.

3 questions about this VFD

I am trying to get it to communicate vis Modbus RTU. I can read from the VFD but I can't write to it. These are the parameters I have set
P0.01 4
P0.02 0
P0.03 2
P0.06 70
P0.17 5
P0.18 5
P0.19 70
P3.09 163
P3.10 100
P4.00 11
P8.01 100
Do I have to have a jumper in place on the terminals for the VFD to run? Also, the LOCAL light is flashing on the front of the VFD, why? Do you have any ideas why I can't write to it?

ATO Responded

1. We confirm that the parameter settings of the VFD are correct. You don't need to set a jumper on the terminal to make the VFD run, but you have to send the run command to the VFD by writing the command. Also, you need to write the running frequency into the address 2001H, then you can run the VFD directly through 485 communication.
2. The LOCAL light on the front of the VFD is blinking, which means that the VFD is controlled to start and stop through 485 communication.
3. May I ask what type of controller you use to send the command 485 communication command? PC or PLC? You can refer to VFD's introduction to the RTU mode command (P167) in the attached manual.

We would like to alter the program of VFD

We have a GK3000-4T0037G VFD.
We would like to alter the program so we can run at different speeds, but we are not sure how to do this.
Could you please follow up with some steps?
We looked through the manual but are still having trouble.
