Indication
Description/Cause
Recovery Method
A.08-01
Over Heated Error
The servo drive circuit does not
function normally due to overheating
of the controller.
1. Ensure that the ambient temperature is 0 ～
45°C.
2. Ensure that the duty cycle conforms to the
specified range.
3. Turn the control power OFF and then turn
ON the power again after waiting for at least
5 minutes.
A.08-02
Watchdog Timer Error
The watchdog timer function of the
controller is not operating correctly.
Breaking or malfunction of the controller may
have occurred.
A.08-04
Over current Error
An overcurrent has occurred in the
controller.
1. Confirm the speed set values.
2. Inspect the tool cable.
3. Breaking or malfunction of the tool cable or
the controller may have occurred.
A.08-05
Over voltage Error
An overvoltage has occurred in the
controller.
1. Confirm the speed set values.
2. Ensure that the power source voltage of the
control power source is 200 ～ 230V AC.
3. Breaking or malfunction of the controller may
have occurred.
A.08-06
Source Voltage Error
1. The internal power source circuit of
the controller does not function
correctly.
2. The power source voltage is not
within the specified ranges.
1. Check the control power wirings.
2. These may occur when an instantaneous
power failure occurs. Check the power
source capacity.
