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, 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 charac-
teristics 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.
• 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.
