Checking Method
1. Check the wiring connections between
drive and motor.

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,

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
