I - 18
Alarm No. Name Meaning
53
Excessive error 2 A difference between the actual and theoretical motor positions
during servo OFF exceeded the setting value.
54
Excessive error 3 When an excessive error 1 occurred, detection of the motor current
failed.
55
External emergency
stop error
There is no contactor shutoff command, even after 30 seconds has
passed since the external emergency stop was input.
57
Option error An invalid option function was selected.
58
Collision detection 1:
G0
When collision detection function was valid, the disturbance torque
in rapid traverse (G0) exceeded the collision detection level.
59
Collision detection 1:
G1
When collision detection function was valid, the disturbance torque
in cutting feed (G1) exceeded the collision detection level.
5A
Collision detection 2 When collision detection function was valid, the command torque
reached the max. motor torque.
5C
Orientation feedback
error
After orientation was achieved, a difference between the command
and feedback exceeded the parameter setting.
5D
Speed monitoring:
Input mismatch
As for door state signal of speed monitoring control, a mismatch
between the external input signal and the control signal received
from the CNC was detected.
5E
Speed monitoring:
Feedback speed
error
In speed monitoring control, the spindle speed was exceeding the
setting speed with the door open.
5F
External contactor
error
A contact of the external contactor is welding. Or the contactor fails
to be ON during ready ON.
61
Power module
overcurrent
Overcurrent protection function in the power module has started its
operation.
62
Frequency error The input power supply frequency increased above the specification
range.
63
Supplementary
regeneration error

65
Rush relay error A resistor relay for rush short circuit fails to be ON.
67
Phase interruption An open-phase condition was detected in input power supply circuit.
68
Watchdog The system does not operate correctly.
69
Grounding The motor power cable is in contact with FG (Frame Ground).
6A
External contactor
welding
A contact of the external contactor is welding.
6B
Rush relay welding A resistor relay for rush short circuit fails to be OFF.
6C
Main circuit error An error was detected in charging operation of the main circuit
capacitor.
6D
Parameter error The capacity of the power supply unit and the regenerative resistor
type that was set in the parameter are mismatched.
6E
Memory error An internal memory error was detected.
6F
Power supply error A power supply unit is not connected. Or an error was detected in
A/D converter of the power supply unit.
71
Instantaneous
power interruption
The power was momentarily interrupted.
