9.2 Potential Cause and Corrective Actions
Servo Drive Fault Messages
: Overcurrent
Potential Cause Checking Method Corrective Actions
Short-circuit at drive
output (U, V, W)
1. Check the wiring connections between
drive and motor.
2. Check if the wire is short-circuited.
Repair the short-circuited and
avoid metal conductor being
exposed.
Motor wiring error
Check if the wiring steps are all correct
when connecting motor to drive.
Follow the wiring steps in the
user manual to reconnect
wiring.
IGBT error Heat sink overheated
Please contact your distributor
for assistance or contact with
Delta.
Control parameter
setting error
Check if the setting value exceeds the
factory default setting.
Set the setting back to factory
default setting and then reset
and adjust the parameter setting
again.
Control command
setting error
Check if the control input command is
unstable (too much fluctuation).
1. Ensure that input command
frequency is stable (too much
fluctuation).
2. Activate filter function.
: Overvoltage
Potential Cause Checking Method Corrective Actions
The main circuit
voltage has
exceeded its
maximum allowable
value.
Use voltmeter to check whether the input
voltage falls within the rated input voltage.
Use correct power supply or
stabilizing power.
Input power error
(Incorrect power
input)
Use voltmeter to check whether the input
voltage is within the specified limit.
Use correct power supply or
stabilizing power.
: Undervoltage
Potential Cause Checking Method Corrective Actions
The main circuit
voltage is below its
minimum specified
value.
Check whether the wiring of main circuit
input voltage is normal.
Reconfirm voltage wiring.
No input voltage at
main circuit.
Use voltmeter to check whether input
voltage at main circuit is normal.
Reconfirm power switch.
Input power error
(Incorrect power
input)
Use voltmeter to check whether the input
voltage is within the specified limit.
Use correct power supply or
serial stabilizing power.
