dEv Speed Deviation
The load is too heavy Decrease the load.
The acceleration/deceleration time is 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:
• Detected if the deviation between the detected speed and the speed reference is greater than the setting in
F1-10
for longer than
F1-11
.
• If the drive detects this error, the terminal assigned to
H2-01 to H2-05 = 10 [MFDO Function Select = Alarm]
will be ON.
