(1) Initializing a 12-bit Absolute Encoder
Use the following procedure to initialize a 12-bit absolute encoder.
1. Properly connect the SERVOPACK, Servomotor, and Machine Controller.
2. Disconnect the connector on the encoder end and short-circuit pins 13 and 14 on the encoder end connec-
tor for 2 seconds or more to reset the "absolute value data" in the encoder.
3. Remove the short piece and insert the connector securely in its original position.
4. Connect the cables using normal wiring and make sure the encoder battery is connected.
5. Turn ON the system.
Repeat the procedure starting from step 1 if an Absolute Encoder Alarm occurs, otherwise the system has
been successfully initialized.
(2) Initializing a 15-bit Absolute Encoder
Use the following procedure to initialize a 15 bit-type absolute encoder.
1. Turn OFF the SERVOPACK and the Machine Controller.
2. Discharge the large-capacity capacitor in the encoder using one of the following methods.
• At the SERVOPACK end connector
a) Disconnect the connector on the SERVOPACK end.
b) Short-circuit pins 10 and 13 on the encoder end connector and leave them short-circuited for at least 2
minutes.
c) Remove the short piece and insert the connector securely in its original position.
• At the encoder end connector
a) Disconnect the connector on the encoder end.
b) Short-circuit together pins R and S at the encoder end and leave them short-circuited for at least 2 min-
utes.
