Modbus transmission
time-out
(CE10)
Modbus transmission time-out occurs
Action and Reset
Action level When the communication time exceeds the detection time for Pr.09-03 time-out.
Action time Pr.09-03
Fault treatment parameter
Pr.09-02
0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning and continue operation
Reset method Manual reset
Reset condition Immediately reset
Record Yes
Cause Corrective Actions
The upper unit does not transmit
the communication command
within Pr.09-03 setting time.
Check if the upper unit transmits the communication command within the setting
time for Pr.09-03.
Malfunction caused by interference
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.
Different communication setting
from the upper unit
Check if the setting for Pr.09-02 is the same as the setting for the upper unit.
Disconnection or bad connection
of the cable
Check the cable and replace it if necessary.

Brake transistor error
(bF)
The brake transistor of the motor drive is abnormal. (for
the models with built-in brake transistor)
Action and Reset
Action level Hardware detection
Action time Immediately act
Fault treatment parameter N/A
Reset method Manual reset
Reset condition Immediately reset
Record Yes
Cause Corrective Actions
Hardware error
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.
Malfunction caused by interference Verify wiring/grounding of the main circuit to prevent interference.
Using the incorrect brake resistor Check if the resistance value of the brake resistor matches to the drive.
Incorrect wiring of the brake
resistor
Refer to the optional accessories instruction in chapter 7, and verify the wiring.
