Rexroth servo drive repair: F8060 electric power part ** overcurrent. Power Supply Unit Supports: - The current in the power transistor bridge exceeds the maximum peak current allowed by the device (see S-0-0110, Amplifier Peak Current).
Taian Rexroth Drive Repair Service Center:
Cause: Insufficient overload capacity of the external 24 V power supply unit.
A short circuit occurs in the motor or motor cable.
The power part of the drive controller is faulty.
The parameter setting of the current regulator is abnormal.
The voltage fluctuation in the bus is too high due to the excessive impedance of the power supply.
Solution: Check the overload capacity of the external 24 V power supply and replace it if necessary, and detect short circuits in the motor cable and motor.
Replace the drive controller.
Check the current regulator parameter settings (see motor sample) and modify them if possible after contacting customer service.
Reduce the impedance of the power supply, e.g. by increasing the lead cross-section.
Common driver faults: no display at power-on, phase loss, overcurrent, undervoltage, overvoltage, module damage, and error. When the machine breaks down, do not disassemble it by yourself or hand it over to non-professionals to avoid unnecessary losses.
