Servomotor Stopping Method for Alarms
There are two types of alarms, group 1 (Gr. 1) alarms and group 2 (Gr. 2) alarms. A different
parameter is used to set the stopping method for alarms for each alarm type.
Refer to the following section to see which alarms are in group 1 and which are in group 2.
12.2.1 List of Alarms on page 12-5
Motor Stopping Method for Group 1 Alarms
When a group 1 alarm occurs, the Servomotor will stop according to the setting of Pn001 =
n.X. The default setting is to stop by applying the dynamic brake.
Refer to the following section for details.

Motor Stopping Method for Group 2 Alarms
When a group 2 alarm occurs, the Servomotor will stop according to the settings of the follow-
ing three parameters. The default setting is for zero clamping.
• Pn001 = n.X (Servo OFF or Alarm Group 1 Stopping Method)
• Pn00A = n.X (Motor Stopping Method for Group 2 Alarms)
• Pn00B = n.X (Motor Stopping Method for Group 2 Alarms)
However, during torque control, the group 1 stopping method is always used.
If you set Pn00B to n.1 (Apply dynamic brake or coast Servomotor to a stop), you can
use the same stopping method as group 1. If you are coordinating a number of Servomotors,
you can use this stopping method to prevent machine damage that may result because of dif-
ferences in the stopping method.
The following table shows the combinations of the parameter settings and the resulting stop-
ping methods.
