AL034 Encoder internal communication error

Condition:

Trigger condition

and cause

1. Internal communication error for the absolute encoder.

2. Internal error for other types of encoder.

Cause: encoder internal communication error.

1. Check if the battery wiring is correct or loose. If it is loose, wire it again and

cycle power on the system.

Checking method

and corrective action

2.

Check if the battery voltage is within the normal range.

3. Internal communication error for the absolute encoder occurs.

Replace the motor.

How to clear the

alarm?

Cycle power on the servo drive.

AL035 Temperature of the encoder or external sensor exceeds the protective range

Trigger condition

and cause

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.

1. Check the encoder temperature (CN2):

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.

2. Check the temperature sensor (CN5):

Checking method

and corrective action

(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.

How to clear the

alarm?

After the temperature becomes lower than 100°C, cycle power on the servo drive.
