12 - 16
12.3 Startup
Confirm that the servo motor operates properly alone before connecting the servo motor with a machine. For
details of the startup in each control mode, refer to section 12.5.1 and 12.6.1.
(1) Power on
When the power is switched on, "C01" (when the identification number is 01h) appears on the servo
amplifier display.
For absolute position detection system, [AL. 25 Absolute position erased] occurs with first power on, and
the servo-on status cannot be made. Cycle the power to deactivate [AL. 25].
If the power is switched on when the servo motor is rotated by an external force at a speed of 3000 r/min
or higher, it may cause a position mismatch. Make sure that the servo motor is not rotated before
switching the power on.
The following shows the procedure for powering on.
(a) Switch off SON (Servo-on).
(b) Make sure that ST1 (Forward rotation start) and ST2 (Reverse rotation start) are off.
(c) Turn on the power.
"C##" (## is the identification No.) is indicated on the display.
(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. Incorrect
setting will result in [AL. 16 Encoder initial communication error 1].
