( 2 ) Initializing a 15-bit Absolute Encoder
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 methods.
■
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.
3.
Connect the cables using normal wiring and make sure the encoder battery is connected.
4.
Turn ON the system.
Repeat the procedure starting from step 1 if an Absolute Encoder Alarm occurs, so the system has been success-
fully initialized.
