8.8 Servo Amplifier Errors [ A8_* ]
• Code A8_1 - SERVO AMPLIFIER ERROR / SERVO IS OVER HEATED
The SAN controller servo circuit has overheated.
CAUSE:
1. The controller servo drive circuit has failed.
2. If the environment temperature is more than 122 degrees Fahrenheit (50 degree centigrade)
without any air flow.
3. Source voltage is very close to the limit (242 VAC) and the environment temperature is also
close to the limit.
RECOVERY:
1. Replace the controller.
2. Provide additional cooling to the enclosure.
3. Verify and correct the source voltage as required.
• Code A8_4 - SERVO AMPLIFIER ERROR / OVER CURRENT
The SAN controller servo circuit experienced a current overload.
CAUSE:
1. The controller servo drive circuit has failed.
2. If the environment temperature is more than 122 degrees Fahrenheit (50 degree centigrade)
without any air flow.
3. Source voltage is very close to the limit (242 VAC) and the environment temperature is also
close to the limit.
4. Maximum force is being run or exceeded by the tool every cycle.
5. Speed may be too low or too high during load speed.
RECOVERY:
1. Replace the controller.
2. Verify proper cooling for the enclosure.
3. Verify and correct the source voltage as required.
4. Verify proper load or work piece.
5. Adjust load speed setting.
• Code A8_5 - SERVO AMPLIFIER ERROR / INTERNAL POWER SUPPLY
The SAN controller servo power supply circuit is not working properly or the input voltage is
above the maximum limit.
CAUSE:
1. The controller internal power supply has failed.
2. Source voltage is very close to the limit (242 VAC) and the environment temperature is also
close to the limit.
RECOVERY:
1. Replace the controller.
2. Provide additional cooling to the enclosure.
3. Verify and correct the source voltage as required.
