5.2.5 Stopping Servomotors after /S_ON Turned OFF or Alarm Occurrence
5-14
(2) Stopping Method for Servomotor When an Alarm Occurs
There are two type of alarms (Gr.1 and Gr.2), depending on the stopping method when an alarm occurs.
Select the stopping method for the servomotor when an alarm occurs using Pn001.0 and Pn00B.1.
The stopping method for the servomotor for a Gr.1 alarm (alarms that result in a DB stop) is set to Pn001.0.
The stopping method for the servomotor for a Gr.2 alarm (alarms that result in a zero-speed stop) is set to
Pn00B.1.
Refer to the information on alarm stopping methods in 10.1.1 List of Alarms.
 Stopping Method for Servomotor for Gr.1 Alarms
The stopping method of the servomotor when a Gr.1 alarm occurs is the same as that for the servomotor after
the /S_ON (Servo ON) signal turns OFF.
 Stopping Method for Servomotor for Gr.2 Alarms
Note: The setting of Pn00B.1 is effective for position control and speed control. Pn00B.1 will be ignored for torque control
and only the setting of Pn001.0 will be valid.
