Code Name
dEv Speed Deviation
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].
Code Name
dv1 Z Pulse Fault
Note:
• The drive detects this error if it does not detect a Z pulse during one motor rotation.
• Do a Fault Reset to clear the fault.

Causes
A drive hardware problem occurred.
Causes
A drive hardware problem occurred.
Causes
A drive hardware problem occurred.
Causes
A drive hardware problem occurred.
Causes
A drive hardware problem occurred.
Causes
The load is too heavy.
Acceleration and deceleration times are set too short.
The dEv detection level settings are incorrect.
The load is locked up.
The holding brake is stopping the motor.
Causes
The encoder option card or the encoder on the motor
side is damaged.
The encoder cable is disconnected or wired
incorrectly.
Possible Solutions
• Re-energize the drive.
• If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact Yaskawa
or your nearest sales representative.

Possible Solutions
Decrease the load.
Increase the values set in C1-01 to C1-08 [Acceleration/
Deceleration Time].
Adjust F1-10 [Speed Deviation Detection Level] and F1-11 [Speed
Deviation Detect DelayTime].
Examine the machine.
Release the holding brake.
Possible Solutions
1. Repair wiring errors and connect disconnected wires. Correctly
ground the shielded wire of the encoder cable.
2. Re-energize the drive
3. If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact Yaskawa
or your nearest sales representative.
