Initializing the MC Unit
1, 2, 3...
An absolute encoder that can be connected to the MC Unit must be set up after
the revolution count data of the encoder has been cleared to zero or after the
encoder has been disconnected from the battery over a long period of time (for
two days or more for OMRON U-series Absolute Encoders). At the same time,
the MC Unit must be initialized.
The reason for this is because the present value of the axis in the MC Unit must
be set to zero when the revolution count data of the absolute encoder has been
cleared to zero.
The absolute encoder setup and MC Unit initialization procedures are described
as follows.
The following setup procedure is for OMRON U-series Absolute Encoders.
1. Connect the battery and wire the Servodriver and Absolute Encoder.
2. Turn ON the Servodriver SEN signal input.
With the MC Unit connected to the Servodriver, turn ON the MC Unit and the
Servodriver. The SEN signal from the MC Unit will turn ON.
The Absolute Encoder will receive a 5-V power supply. Leave the power ON
for at least 3 minutes to fully charge the backup capacitor. Do not issue servo
lock commands from the MC Unit during this operation.

3. Turn OFF the Servodriver and MC Unit, then disconnect the encoder con-
nector.
4. Short-circuit the encoder connector terminals 13 and 14 for one or two
seconds.
5. Reconnect the encoder connector.
6. Turn ON the Servodriver and MC Unit. Then, initialize the MC Unit.
1. Check that the pin 1 of the DIP switch on the rear of the MC Unit is set to OFF.
If this pin is set to ON, an error will occur when the MC Unit is initialized.
2. Release the servo lock.
If the servo lock is applied, an error will occur when the MC Unit is initialized.
