Condition:
Internal communication error for the absolute encoder.
1.
Internal error for other types of encoder.
2.
Cause: encoder internal communication error.
Check if the battery wiring is correct or loose. If it is loose, wire it again and
1.
cycle power on the system.
Check if the battery voltage is within the normal range.
2.
Internal communication error for the absolute encoder occurs.
3.
Replace the motor.
Cycle power on the servo drive.
Condition: the temperature of the encoder connected through CN2 is over the
upper limit of 100°C (212°F) or the temperature detected by the sensor connected
through CN5 exceeds the protective range set by PM.022 and PM.024.
Cause: a temperature rise is detected in the encoder connected to CN2 or in the
temperature sensor connected to CN5.
Check the encoder temperature (CN2):
1.
Set P0.002 to -124 to read the temperature and check if it is below 100°C.
If the encoder temperature is higher than 100°C, improve the heat dissipation
to lower the temperature. If the temperature difference between the encoder
and motor is over 30°C (86°F), send the servo motor back to Delta.
Check the temperature sensor (CN5):
2.
(a) If not using the temperature sensor, set PM.022 to 0.
(b) When PM.022 = 1, set P0.002 to -145 to read the temperature and check
if it is below 100°C. If the temperature of the sensor is higher than 100°C,
improve the heat dissipation to lower the temperature. If the temperature
difference between the temperature sensor and motor is over 30°C, send
the servo motor back to Delta.
(c) When PM.022 = 2 or 3, check if the setting of PM.024 is correct and the
temperature sensor works normally. If so, improve the heat dissipation to
lower the temperature.
After the temperature becomes lower than 100°C, cycle power on the servo drive.
