Alarm Displays
If the SERVOPACK detects an alarm, it stops the motor with the motor stop method for alarms that is
described below and displays the alarm status.
Status Indications
∗
For details, refer to
11.4 Monitoring Communications Data When Alarms or Warnings Occur
.
Motor Stop Method for Alarms
Gr.1: The alarm stopping method depends on the setting of Pn01E.0.
If Pn01E.0 = 0 and a SERVOPACK with a capacity of 5 kW max. is used:
The stopping method set in Pn001.0 is used. Stopping is performed with dynamic braking (DB) in the
factory setting.
If Pn01E.0 = 0 and a SERVOPACK with a capacity that exceeds 5 kW max. is used:
A coasting to a stop is performed.
If Pn01E.0 = 1 to 8:
A coasting to a stop is performed.
Gr.2: The motor is stopped according to the setting in Pn00B.1 if an alarm occurs. Pn00B.1 is factory-set to
stop the motor by setting the speed reference to “0.” The motor under torque control will always use the
Gr.1 method to stop. By setting Pn00B.1 to 1, the motor stops using the same method as Gr.1. When
coordinating a number of motors, use this alarm stop method to prevent machine damage that may result
due to differences in the stop method.
Resetting Alarms
Available: Removing the cause of alarm and then executing the alarm reset can clear the alarm.
N/A: Executing the alarm reset cannot clear the alarm.
The alarm name, alarm meaning, motor stop method for alarms, and alarm reset capability are listed in order
of the alarm numbers in
11.2.1 List of Servo Drive Alarms
and
11.2.2 List of Alarms for EtherCAT (CoE)
Communications
.
The probable causes of alarms and corrective actions are provided in
11.2.3 Troubleshooting of the Servo
Drive Alarms
and
11.2.4 Troubleshooting of the EtherCAT (CoE) Communications
.
