3.1 Startup
Connect the servo motor with a machine after confirming that the servo motor operates properly alone.
(1) Power on
When the power is switched on, "b01" (when the identification number is 01h) appears on the servo
amplifier display.
When you use the absolute position detection system, first power-on results in [AL. 25 Absolute position
erased] and the servo-on cannot be ready. [AL. 25] can be deactivated by cycling the power.
Also, if the power is switched on when the servo motor is rotated at a speed of 3000 r/min or higher, a
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.
(2) Parameter setting
POINT
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. An
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. Refer to chapter 4 for
details.
After setting the above parameters, turn off the power as necessary. Then switch power on again to
enable the parameter values.
(3) Servo-on
Enable the servo-on with the following procedure.
(a) Turn on the power.
(b) 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.
