Alarm Status
Segment LED Alarm Code
Display ALM8,4,2,1
Alarm code 0,1 indicates: when Func2/ bit7,6 ="0,0", "0"= output open and "1"= output short.
Operating state when alarm occurred
OPERATING STATE
When control power supply is turned on
Upon servo ON input
Upon command input
When motor is started or stopped
Corrective Measures
1 Incorrect wiring of U, V, W phases between
amplifier and motor
2 Incorrect wiring of A, B phases between
INC-E and ABS-E encoder connection
3 Motor is vibrating (oscillating)
4 Overshoot and/or undershoot is too large
4 Faulty servo amplifier control circuit
Velocity control error alarm is set to "not detecting" as standard, but can be change to
"detecting" by setting bit5 of Func2 to "0" when necessary.
This alarm may be detected during motor start or stop in cases where load inertia is high or
for applications with G-force axis. In these cases, set bit5 of Func2 to "1" for "not detecting".

Check and correct wiring.
Check and correct wiring.
Adjust servo parameter to stop vibration (oscillation).
Use the analog monitor of the remote controller to
check the velocity
• Adjust servo parameter to reduce overshoot and/or
undershoot.
• Increase acceleration/deceleration command time.
Or, mask the alarm by setting Func2 of remote
controller.
Replace servo amplifier.
