: Adjustment error
Potential Cause
Checking Method
Corrective Actions
Analog input contact
does not correctly return
to zero.
Measure and check if the voltage level of
analog input contact is the same as the
electrical potential of grounding.
Correctly ground analog input contact.
Detection device may be
damaged.
Check and reset the power supply.
If the error does not clear after
resetting the power supply, contact the
distributor for assistance or return to
manufacturer.
: Emergency stop activated
Potential Cause
Checking Method
Corrective Actions

Potential Cause
Checking Method
Corrective Actions
Reverse limit switch is
disabled.
Check if reverse limit switch is On or Off. Activate reverse limit switch.
Servo system is not
stable.
Check the value of control parameter
setting and load inertia.
Modify parameter setting and estimate
motor capacity again.
: Forward limit switch error
Potential Cause
Checking Method
Corrective Actions
Forward limit switch is
disabled.
Check if forward limit switch is On or Off. Activate forward limit switch.
Servo system is not
stable.
Check the value of control parameter
setting and load inertia.
Modify parameter setting and estimate
motor capacity again.
: IGBT temperature error
Potential Cause
Checking Method
Corrective Actions
The drive has exceeded
its rated load during
continuous operation.
Check if there is overload or the motor
current is too high.
Increase motor capacity or reduce
load.
Short-circuit at drive
output
Check the drive input wiring.
Make sure to wire correctly.
