Alarm
Code
Name
Details
What to inspect
Check regenerative resistance.
RST power fail
Main power failure
Check power unit wiring and power.
Control power fail
Control power failure
Check power unit wiring and power.
Over speed limit
Overspeed
Check the encoder, encoder setting, encoder
wiring, gain setting, motor wiring, motor ID,
electric gear ratio, and speed command scale.
Position following
Excessive position error
Check the excessive position command pulse
setting [P4-11], wiring, limit contact point, gain
setting, encoder setting, and electric gear ratio.
Check for equipment confinement and load.
EMG
Emergency stop
Check the emergency stop contact signal,
external 24 V power, and contact points.
Over pulse CMD
Pulse command frequency
error
Check pulse command frequency from the
upper level controller.
Check command pulse type.
Parameter checksum
Parameter error
Factory reset [Cn-17].
Parameter range
Parameter range error
Factory reset [Cn-17].
Invalid factory setting
Invalid factory setting
Factory reset [Cn-17].
GPIO setting
Output contact point setting
error
Factory reset [Cn-17].
If a warning code is displayed in the current operation status [St-00], the servo drive is
operating abnormally. Check what needs to be inspected for the issue.
Warning
State
(CODE)
Name
Details and cause
What to inspect
RST_PFAIL
Main power phase loss
If the [P0-06] DIGIT 2 is set to 1, the main
power fails.
LOW_BATT
Low battery
OV_TCMD
Excessive torque command
More than the maximum torque commands
have been entered.
OV_VCMD
Overspeed command
More than the maximum speed commands
have been entered.
OV_LOAD
Overload warning
The maximum overload [P0-13] has been
reached.
SETUP
Capacity setting
The electric current capacity of the motor is
bigger than that of the drive.
UD_VTG
Low voltage warning
When [P0-06] DIGIT 2 is set to 1, the DC link
voltage is 190 V or below.
EMG
EMG contact point
Check the I/O wiring and [P2-09] setting
Warning code is displayed to hexadecimal. If the over 2 warning codes occurs, the sum of
warning codes will be displayed. For example, if [W-04] Excessive Toque Command and [W-
08] Excessive Speed Command are occurred at the same time, [W-0C] will be displayed.
- If warning code 80 occurs,
“SV-ON” state changes to “SV-OFF” state automatically.
-To avoid warning code 80, wire EMG contact or change EMG input signal logic definition.
