1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 61
Alarm No.: 56 Name: Forced stop error
Alarm content The servo motor does not decelerate normally during forced stop deceleration.
Detail
No.
Detail name Cause Check method Check result Action Target
56.2 Over speed
during forced
stop
(1) The forced stop
deceleration time
constant is short.
[A]: [Pr. PC51]
[B] [WB] [RJ010] [GF]:
[Pr. PC24]
Increase the
parameter setting
value, and then check
the repeatability. It is not repeatable. Adjust the
deceleration time
constant. [A]
[B]
[WB]
[RJ010]
[GF]
It is repeatable. Check (2).
(2) The torque limit has
been enabled.
Check if the limiting
torque is in progress. The limiting torque
is in progress. Review the torque
limit value.
The limiting torque
is not in progress. Check (3).
(3) The servo system is
unstable and
oscillating.
Check if the servo
motor is oscillating.
Check the torque
ripple with MR
Configurator2. The torque ripple is
vibrating. Adjust the servo
gain. Set the
machine resonance
suppression filter.
The torque ripple is
not vibrating. Check (4).
(4) The encoder or linear
encoder is
malfunctioning.
Replace the servo
motor or linear
encoder, and then
check the
repeatability. It is not repeatable. Replace the servo
motor or linear
encoder.
56.3 Estimated
distance over
during forced
stop
(1) The forced stop
deceleration time
constant is short.

is in progress. Review the torque
limit value.
The limiting torque

(3) The encoder or linear
encoder is
malfunctioning.
Replace the servo
motor or linear
encoder, and then
check the
repeatability. It is not repeatable. Replace the servo
motor or linear
encoder.
Alarm No.: 61 Name: Operation error
Alarm content An operation of the positioning function failed.
Detail
No.

61.1 Point table
setting range
error
(1) "1" or "3" was set to the
sub function of the last
point table (255).
Check if "1" or "3" was
set.
It was set. Review the settings. [A]
