[Comparator 2 Upper Limit] .
Examine the monitor value setting and remove the cause of the
fault.
Note:
• This fault is detected when the terminal is assigned to
H2-01 to H2-05 = 67 [MFDO Function Select = Comparator2]

Code Name Causes Possible Solutions
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] .
