dEv Speed Deviation The load is too heavy. Decrease the load.
Acceleration and deceleration times are set too short. Increase the values set in C1-01 to C1-08 [Acceleration/
Deceleration Time] .
The dEv detection level settings are incorrect. Adjust F1-10 [Speed Deviation Detection Level] and F1-11 [Speed
Deviation Detect DelayTime] .
The load is locked up. Examine the machine.
The holding brake is stopping the motor. Release the holding brake.
Note:
• The drive detects this error if the difference between the detected speed and the speed reference is more than the setting of F1-10 for longer than F1-11 .
• Do a Fault Reset to clear the fault.
• If the drive detects this error, the drive will operate the motor as specified by the stopping method set in F1-04 [Speed Deviation Detection Select] .

The encoder option card or the encoder on the motor
side is damaged.
The encoder cable is disconnected or wired
incorrectly.
1. Repair wiring errors and connect disconnected wires. Correctly
