List of alarm No./warning No.

Explanation of the list

Motor stop method
Alarms and warnings which have "SD" in the "Motor stop method" column stop the servo motor with the dynamic brake after
forced stop deceleration. Alarms and warnings which have "DB" or "EDB" in the "Motor stop method" column stop the servo
motor with the dynamic brake.
■Stop method at occurrence of alarms/warnings
The servo amplifier has the following stop methods:
Motor stop method Description
DB Dynamic brake stop (for a servo amplifier without the dynamic brake, the servo motor coasts)
SD Forced stop deceleration
The stop method is applicable when [Pr. PA04] is set to the initial value. The stop method can be changed from SD to DB with
[Pr. PA04].
EDB Stop with an electronic dynamic brake (enabled only for specific servo motors)
Refer to "Stop method at occurrence of alarms/warnings" in the following manual for the specific servo motors.
MR-J5 User's Manual (Function)
STO/DB Dynamic brake stop by the STO function (for a servo amplifier without the dynamic brake, the servo motor coasts)
SS1/SD Forced stop deceleration by the SS1 function
The stop method is applicable when [Pr. PA04] is set to the initial value. The stop method can be changed from SS1/SD to
SS1/DB with [Pr. PA04].
SS1/EDB Stop with an electronic dynamic brake (enabled only for specific servo motors)
Refer to "Stop method at occurrence of alarms/warnings" in the following manual for the specific servo motors.
MR-J5 User's Manual (Function)
The stop method of SS1/DB is applicable to servo motors other than the said specific servo motors.
■Specific stop methods
Quick stop or slow stop can be selected with [Pr. PD30] if the MR-J5-_A_ is used.
Alarm deactivation
When using servo motors with functional safety, executing software reset may trigger [AL. 016 Encoder initial
communication error 1]. If [AL. 016] occurs, cycle the power.
After the cause of the alarm has been removed, the alarm can be deactivated by using the methods marked with "" in the
"Alarm deactivation" column. Alarms marked with "" in the "Alarm deactivation" column have the deactivation conditions.
Page 7 Restrictions
Alarms are deactivated by alarm reset, communication reset, or power cycling. Alarms can also be deactivated by software
reset instead of power cycling.
Refer to "Alarm function" in the following manual.

Stop system
This stop system is applicable only for the MR-J5W_-_G_.
This indicates which axis to stop when an alarm or a warning occurs.
Each axis: Only the axis where the alarm or warning occurred will stop.
All axes: All axes will stop.
Motor stop warning
Warnings that have "" in the "Motor stop warning" column stop the servo motor when the warning occurs. If a warning that
stops the servo motor occurs, WNGSTOP (Motor stop warning) will turn on.
