11.2 Potential Cause and Corrective Actions

Servo Drive Fault Messages
: Overcurrent
Potential Cause
Short-circuit at drive
output (U, V, W)
Motor wiring error
IGBT error
Control parameter
setting error
Control command
setting error
: Overvoltage
Potential Cause
The main circuit voltage
has exceeded its
maximum allowable
value.
Input power error
(Incorrect power input)
The hardware of the
servo drive is damaged.
: Undervoltage
Potential Cause
The main circuit voltage
is below its minimum
specified value.
No input voltage at
main circuit.
Input power error
(Incorrect power input)
11-6
Checking Method
1. Check the wiring connections between drive
and motor.
2. Check if the wire is short-circuited.
Check if the wiring steps are all correct when
connecting motor to drive.
Heat sink overheated
Check if the setting value exceeds the factory
default setting.
Check if the control input command is unstable
(too much fluctuation).
Checking Method
Use voltmeter to check whether the input
voltage falls within the rated input voltage.
(For voltage specification, please refer to
section 12.1 in Chapter12.)
Use voltmeter to check whether the input
voltage is within the specified limit.
Use voltmeter to ensure that the main circuit
input voltage falls within the specified limit,
Checking Method
Check whether the wiring of main circuit input
voltage is normal.
Use voltmeter to check whether input voltage at
main circuit is normal.
Use voltmeter to check whether the input
voltage is within the specified limit.
Corrective Actions
Repair the short-circuited and avoid
metal conductor being exposed.
Follow the wiring steps in the user
manual to reconnect wiring.
Please contact your distributor for
assistance or contact with Delta.
Set the setting back to factory
default setting and then reset and
adjust the parameter setting again.
1. Ensure that input command
frequency is stable (too much
fluctuation).
2. Activate filter function.
Corrective Actions
Use correct power supply or
stabilizing power or using series
transformer.
Use correct power supply or
stabilizing power or using series
transformer.
If the error does not clear even if
the main circuit input voltage falls
within the specified limit, please
contact your distributor for
assistance or contact with Delta.
Corrective Actions
Reconfirm voltage wiring.
Reconfirm power switch.
Use correct power supply or
stabilizing power or using series
transformer.
