9.9 Servo Amplifier Error
9.9.1 Code 8-1 SERVO AMPLIFIER ERROR / SERVO IS OVER HEATED
The SAN controller servo circuit has overheated.
This abnormal is caused from;
1. The controller servo drive circuit has failed.
2. If the environment temperature is more than 122 degrees Fahrenheit (50 degree centi-
grade) without any air flow.
3. Source voltage is very close to the limit (242 volts ac) 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.
9.9.2 Code 8-4 SERVO AMPLIFIER ERROR / OVER CURRENT
The SAN controller servo circuit experienced a current overload.
This abnormal is caused from;
1. The controller servo drive circuit has failed.
2. If the environment temperature is more than 122 degrees Fahrenheit (50 degree centi-
grade) without any air flow.
3. Source voltage is very close to the limit (242 volts ac) and the environment temperature is
also close to the limit.
4. Maximum torque is being run or exceeded by the tool every cycle.
5. Speed may be too low or too high during torque speed. (Confirm that Crossover Torque is
not set between 95% - 100% of Standard Torque – See note @ 6.3)
RECOVERY:
1. Replace the controller
2. Verify proper cooling for the enclosure.
3. Verify and correct the source voltage as required.
4. Verify proper torque or work piece.
5. Adjust torque speed setting.
9.9.3 Code 8-5 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.
This abnormal is caused from;.
1. The controller internal power supply has failed
2. Source voltage is very close to the limit (242 volts ac) and the environment temperature is
also close to the limit.
3. If the environment temperature is more than 122 degrees Fahrenheit (50 degree centi-
grade) without any air flow.
RECOVERY:
1. Replace the controller
2. Provide additional cooling to the enclosure.
3. Verify and correct the source voltage as required.
