When in Trouble
What to Check ?
Protective Function (What is Error Code ?)
• Various protective functions are equipped in the driver. When these are triggered, the motor will stall due
to error, according to P.43, "Timing Chart (When error occurs)"of Preparation, and the driver will turn the
Servo-Alarm output (ALM) to off (open).
• Error status ands their measures
• During the error status, the error code No. will be displayed on the front panel LED, and you cannot turn
Servo-ON.
• You can clear the error status by turning on the alarm clear input (A-CLR) for 120ms or longer.
• When overload protection is triggered, you can clear it by turning on the alarm clear signal (A-CLR) 10
sec or longer after the error occurs. You can clear the time characteristics by turning off the connection
between L1C and L2C or r and t of the control power supply of the driver.
•You can clear the above error by operating the front panel keys.
(Refer to P.73, "Alarm Clear Mode" of Preparation.)
•You can also clear the above error by operating the "PANATERM
®
".
<Remarks>
• When the protective function with a prefix of "*" in the protective function table is triggered, you cannot
clear with alarm clear input (A-CLR). For resumption, shut off the power to remove the cause of the error
and re-enter the power.
• Following errors will not be stored in the error history.

Aren't the parameter
setups wrong ?
Motor does not run.
Check the cause by referring to P.68,
“Display of Factor of No Motor Running” of
Preparation, and then take necessary measure.
