(2) Remedies for alarms
CAUTION
When an alarm occurs, reset the alarm after removing the cause and ensuring
safety. Then, restart the operation. Otherwise, injury may occur.
If an absolute position erase (A25) occurs, be sure to set the home position again.
Not doing so may cause unexpected operation.
As soon as an alarm occurs, turn off Servo-on (RYn0) and power off.
POINT
When any of the following alarms has occurred, do not deactivate the alarm
and resume operation repeatedly. To do so will cause the servo
amplifier/servo motor to fail. Remove the cause of occurrence, and leave a
cooling time of 30 minutes or longer before resuming operation.
Regenerative error (A30) Main circuit device overheat (A45)
Servo motor overheat (A46) Overload 1 (A50)
Overload 2 (A51)
For the alarm deactivation method, refer to (1) in this section.
Parameter error (A37) is not recorded in the alarm history.
When an alarm occurs, the malfunction (ALM) switches off and the dynamic brake is operated to stop the
servo motor. At this time, the display indicates the alarm No.
Remove the cause of the alarm in accordance with (2) of this section. Use MR Configurator to refer to a
factor of alarm occurrence. Use the alarm history of MR Configurator to refer to the alarm detailed
information.
