9.9.4 code 8-3 servo amplifier error / servo is over heated
The controller Servo circuit is not working properly.
This abnormal is caused from only 3 items.
1. The controller servo drive circuit has failed
2. If the environment temperature is more than 113 degrees Fahrenheit(45 degree
centigrade) without any air flow.
3. Source voltage is very close to the limit (253 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.
9.9.5 code 8-4 servo amplifier error / encoder is over heated
The controller Encoder circuit is not working properly.
This abnormal is caused from only 3 items.
1. the controller encoder circuit has failed
2. If the environment temperature is more than 113 degrees Fahrenheit(45 degree
centigrade) without any air flow.
3. Source voltage is very close to the limit (253 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.
9.9.6 code 8-5 servo amplifier error / over source voltage
The controller internal power supply circuit is not working properly or the input voltage is
above the maximum limit.
This abnormal is caused from only 2 items.
1. The controller internal power supply has failed
2. Source voltage is very close to the limit (253 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.
