Condition: communication error occurs when the Delta position signal converter
box is connected to the CN2 connector.
Cause:
A communication error occurred to the position signal converter box.
1.
A communication error occurred during the Motor Parameter Identification
2.
Wizard setting process.
Check the wiring of the position signal converter box.
1.
Check for the encoder cable and connector which connect the motor and
2.
CN2 of the servo drive to see if there is any poor wiring or damaged wires.
If so, replace the connector and cable.
Check the communication error rate by setting P0.002 to -80. If this value

increases continuously, it means there is interference. Check the following
items:
(a) Check if the motor is properly grounded. Make sure the ground end
(green) of the power cable is grounded to the servo drive heat sink.
(b) Check if the connection for the encoder signal cable is normal.
Make sure the encoder signal cable is separated from the power supply
or any high-current cables to avoid interference.
(c) Use shielded cable for the encoder cable. Pull out the wire mesh and
have it correctly grounded.
If you took all corrective actions but the issue persists, replace the motor.
Cycle power on the servo drive.
Condition: losing the recorded number of revolutions because of low battery
voltage or loss of power.
Cause:
Voltage level of the battery is too low.
1.
The battery is replaced when the main power of the servo drive is off.
2.
The battery is not installed when the absolute function is enabled.
3.
Poor connection or disconnection of the battery power circuit.
