dEv
Speed Deviation (for Control Mode with PG)
The deviation between the speed reference and speed feedback is greater than the setting in
F1-10 for longer than the time set to F1-11.
Cause
Possible Solutions
Load is too heavy.
• Check the size of the load.
• Reduce the load.
Acceleration and deceleration times are set too
short.
Increase the acceleration and deceleration times (C1-01 through C1-08).
The load is locked up.
Check the machine.
Parameters are not set appropriately.
Check the settings of parameters F1-10 and F1-11.
Motor brake is engaged.
Ensure the motor brake releases properly.

Fault Name
dO
Door Open
The contact input terminal from the door limit switch has detected that the panel door is open.
(Fault detected when the terminal is open. No fault detected when the terminal assigned for
H1-
= 73 is closed.)
Cause
Possible Solutions
The panel door is open.
Close the panel door.
The contact input terminal remains open.
• Check for disconnected cables and faulty wiring.
• Correct the wiring.
• Check that limit switch is operating normally.
• Replace the limit switch.

Option Card External Fault
An external fault condition is present.
Cause
Possible Solutions
An external fault was received from the PLC and
F6-03 was set to a value other than 3 “alarm
only” (the drive continued to run after external
fault).
• Remove the cause of the external fault.
• Remove the external fault input from the PLC.
Problem with the PLC program
Check the PLC program and correct problems.
