9.2. Alarm cause and remedy
AL01 Over voltage
Cause
Inspection
Remedy
Power supply voltage excess
Review the power voltage.
Use the proper power source.
Input power error (incorrect power). Review the power supply.
Use proper power source.
Drive hardware damaged.
Use voltmeter to check if the power
voltage is within rated voltage while
error still occurred.
Contact agent for proper service.
Lead of built-in regenerative brake
resistor or regenerative brake
option is disconnected.
Check the P,D terminals connected
well or not.
Check built-in regenerative brake
resistor or regenerative brake
option is disconnected well.
Connect correctly.
Built-in regenerative brake resistor
or regenerative brake option is
damaged.
Check if it is burn out or damaged.
Change the built-in resistor or
option.
Capacity of built-in regenerative
brake resistor or regenerative
brake option is insufficient.
Check if the capacity insufficient.
Add regenerative brake option or
increase capacity.
AL02 Low voltage
Cause
Inspection
Remedy
Input voltage of main circuit is lower
than permissible value.
Review the power supply.
Use proper power source.
Capacity of power supply is
insufficient.
Check if it occurred as motor torque
regenerated huge.
Increase power supply capacity.
Input power error (incorrect power). Review the power supply.
Use proper power source.
AL03 Over current
Cause
Inspection
Remedy
Improper motor wirings.
Check the wirings.
Correct the wirings.
Short occurred in drive output
phases U, V and W.
Check if the connection between
drive and motor is short.
Correct the wirings to prevent from
short-circuit or cable naked.
IGBT of servo drive faulty.
AL03 occurs if power is switched on
after U,V and W are disconnected.
Contact agent for proper service.
Improper parameters setting.
Check relevant parameters which
have modified.
Recover factory-set then re-define
user
‟s demand.
