TROUBLESHOOTING
SERVICE MANUAL –ALPHA SL 65S
AL067 Motor temperature
warning The temperature of motor is over 85°C (185°F).
AL099 DSP firmware
upgrade EE-PROM is not reset after the firmware version is upgraded.
This fault can be cleared after setting P2-08 to 30 first, and then
setting P2-08 to 28 next and restarting the servo drive.
ALARMS CAUSE AND SOLUTIONS
AL001 Overcurrent
Clearing Method Turn ARST (DI signal) ON to clear the fault or restart the servo drive.
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.
AL002 Overvoltage
Clearing Method Turn ARST (DI signal) ON to clear the fault or restart the servo drive.
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.
