2. OPERATION
Servo on

When the servo-on signal (SON) is switched on, the servo amplifier
is ready to operate and the servo motor shaft is locked. (Servo lock
state) If the shaft is not servo-locked, SON is not on. Check the
external sequence on the diagnostic display.
Checking procedure
Power on
Press MODE once.
Switch SON on.

lection 1 signal (SP1) and speed se-
lection 2 signal (SP2) and switch-
ing on the start signal (ST1/ST2),
the servo motor starts rotating.
First, run the servo motor at low
speed and check the rotation direction, etc. If the servo motor
does not run as expected, check the input signals and param-
eters.
• On the status display monitor, check the servo motor speed, load
ratios, etc.
• When machine operation check is over, confirm automatic opera-
tion with the host controller or the like.
• This servo amplifier has the real-time auto tuning function under
model adaptive control. Therefore, starting servo operation auto-
matically makes gain adjustment. Using parameter No. 2, response
level setting can be adjusted to provide the optimum tuning ac-
cording to machine rigidity.
