4. STARTUP
(1) Power on
When the main and control circuit power supplies are turned on, "b01" (for the first axis) 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.
(2) Parameter setting
Set the parameters according to the structure and specifications of the machine. Refer to chapter 5 for
details.
After setting the above parameters, switch power off as necessary. Then switch power on again to
enable the parameter values.
(3) Servo-on
Enable the servo-on with the following procedure.
(a) Switch on main circuit power supply and control circuit power supply.
(b) Transmit the servo-on command with the servo system controller.
When the servo-on status is enabled, the servo amplifier is ready to operate and the servo motor is
locked.
(4) Home position return
Always perform home position return before starting positioning operation.
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. Incorrect
setting will result in [AL. 16 Encoder initial communication error 1].
