C Initializing the Absolute Encoder
( 2 ) Initializing a 15-bit Absolute Encoder
C-8
Use the following procedure to initialize a 15-bit absolute encoder.
1.
Turn OFF the SERVOPACK and MP2300.
2.
Discharge the large-capacity capacitor in the encoder using one of the following meth-
ods.
■ At the SERVOPACK End Connector
1) Disconnect the connector on the SERVOPACK end.
2) Use a short piece to short-circuit together connector pins 10 and 13 on the encoder end and
leave the pins short-circuited for at least 2 minutes.
3) Remove the short piece and insert the connector securely in its original position.
■ At the Encoder End Connector
1) Disconnect the connector on the encoder end.
2) Use a short piece to short-circuit together connector pins R and S on the encoder end and
leave the pins short-circuited for at least 2 minutes.
3) Remove the short piece and insert the connector securely in its original position.
