Startup
Confirm that the servo motor operates properly before connecting with a machine.
Power on
When the main and control circuit power supplies are turned on, "b01" (for the first station) appears on the servo amplifier
display.
When the absolute position detection system is used in a rotary servo motor, first power-on results in [AL. 25 Absolute position
erased] and the servo-on cannot be ready. The alarm can be deactivated by then switching power off once and on again.
Also, if power is switched on at the servo motor speed of 3000 r/min or higher, position mismatch may occur due to external
force or the like. Power must therefore be switched on when the servo motor is at a stop.
Parameter setting
The following encoder cables are of four-wire type. When using any of these encoder cables, set [Pr. PC04] to
"1 _ _ _" to select the four-wire type. Incorrect setting will result in [AL. 16 Encoder initial communication error
1].
MR-EKCBL30M-L
MR-EKCBL30M-H
MR-EKCBL40M-H
MR-EKCBL50M-H
Set the parameters according to the structure and specifications of the machine.

After setting the above parameters, turn power off as necessary. Then switch power on again to enable the parameter values.
Servo-on
Enable the servo-on with the following procedure.
1.
Switch on main circuit power supply and control circuit power supply.
2.
Transmit the servo-on command with the controller.
When the servo-on status is enabled, the servo amplifier is ready to operate and the servo motor is locked.
Home position return
Always perform home position return before starting positioning operation.
