Servo amplifier
Error code, error content and action are given for the MR-J3- B(S).
Parentheses ( ) in the error code column indicate the LED display of the MR-J3- B(S).
→
For the MR-J3W- B, refer to the MR-J3W- B Instruction Manual
→
For details on how to check errors and actions, refer to the manual of the servo amplifier to be connected

Cooling fan alarm
•
The cooling fan of the servo amplifier
stopped.
•
The rotation speed of the fan fell below the alarm
level.
•
Replace the cooling fan of the servo amplifier.
•
Remove any debris
•
Replace the servo amplifier.

Overload 1
The load exceeded the overload protection
characteristics of the servo amplifier.
•
The servo amplifier is exceeding its continuous
output current rating.
-
Reduce the load.
-
Review the operation pattern.
-
Use a servo motor that provides larger output.
•
Machine collision occurred.
-
Review the operation pattern.
-
Install limit switches.
•
Connect the servo motor correctly.
•
Servo system is unstable due to servo hunting
(jittering).
-
Repeat acceleration/deceleration to execute
auto tuning.
-
Change the auto tuning response setting
(servo parameter).
→
Refer to Subsection 11.2.1
-
Set the auto tuning mode (servo parameter) to
OFF and manually adjust the the gain.
→
Refer to Subsection 11.2.1
•
Replace the servo motor.

Overload 2
•
A machine collision or other similar factor has
caused the max. output current to flow
continuously for several seconds.
Servo motor
-
Locked
:1s or more
-
During rotation
:2.5s or more
•
Machine collision occurred.
-
Review the operation pattern.
-
Install limit switches.
•
Connect the servo motor correctly.
•
Hunting is occurring due to an unstable servo
system.
-
Repeat acceleration/deceleration to execute
auto tuning.
-
Change the auto tuning response setting
(servo parameter).
→
Refer to Subsection 11.2.1
-
Set the auto tuning mode (servo parameter) to
OFF and manually adjust the gain.
→
Refer to Subsection 11.2.1
•
Replace the servo motor.

(52)
Excessive error
The deviation between the model position and the
actual servo motor position exceeds the excessive
error alarm level (servo parameter) setting value
(default: 3 rotations).
→
Refer to Subsection 11.2.3
•
Increase the acceleration/deceleration time
constant.
•
Increase the torque limit value.
•
The motor cannot be started due to insufficient
torque caused by a power supply voltage drop.
-
Review the power supply capacity.
-
Use a servo motor with larger output.
•
Increase the value of model control gain (servo
parameter) and adjust to ensure proper operation.
→
Refer to Subsection 11.2.2
•
The servo motor shaft was rotated by an external
force.
-
When the torque is limited, increase the limit
value.
-
Reduce the load.
-
Use a servo motor with larger output.
•
Machine collision occurred.
-
Review the operation pattern.
-
Install limit switches.
•
Replace the servo motor.
•
Connect the servo motor correctly.
•
Replace the SSCNET III cable.
