Fault Name
MODBUS transmission
time-out MODBUS transmission time-out occurs
(CE10)
Action and Reset
When the communication time exceeds the detection time for Pr.09-03 time-out.
Pr. 09-03
Pr. 09-02
0: Warn and continue operation
1: Warn and ramp to stop
2: Warn and coast to stop
3: No warning and continue operation
Manual reset
Immediately reset
Yes
Check if the upper unit transmits the communication command within the setting
time for Pr.09-03.
Verify the wiring and grounding of the communication circuit. It is recommended
to separate the communication circuit from the main circuit, or wire in 90 degree
for effective anti-interference performance.
Check if the setting for Pr.09-02 is the same as the setting for the upper unit.
Check the cable and replace it if necessary.
Fault Name
Brake transistor error The brake transistor of the motor drive is abnormal. (for
(bF) the models with built-in brake transistor)
Action and Reset
Hardware detection
Immediately act
N/A
Manual reset
Immediately reset
Yes
1. Press "RESET" key to go back to the default. If bF still exists, return to the
factory for repair.
2. Power off the motor drive since the internal circuit is abnormal. Use a meter
to check if it is short-circuit between B2 to DC-. If short-circuit exists, return
to the factory for repair.
Check if the resistance value of the brake resistor matches to the drive.
Refer to the optional accessories instruction in chapter 7, and verify the wiring.
