(3) Operating Procedure in Position Control Mode (Pn000 = n.††1†)
The following circuit is required: External input signal circuit or equivalent.
Step Description Check Method and Remarks
1 Match the reference pulse form with the pulse out-
put form from the host controller. Set the reference pulse with Pn200=n.††† ×. Refer
to 8.6.1 (2) Setting a Reference Pulse Form.
2 Set the reference unit and electronic gear ration so
that it coincides with the host controller setting. Set the electronic gear ratio with Pn202/Pn203. Refer
to 8.6.2 Setting the Electronic Gear.
3 Turn ON the power and the servo ON (/S-ON) input
signal. −
4 Send the pulse reference for the number of motor
rotation easy to check (for example, one motor revo-
lution) and with slow speed from the host controller
in advance.
Set the motor speed of several 100 min
-1
for the refer-
ence pulse speed because such speed is safe.
5 Check the number of reference pulses input to the
SERVOPACK by the changed amount before and
after the Un00C (input reference pulse counter)
[pulse] was executed. Refer to 7.1.3 Basic Mode Selection and Operation for
how it is displayed.
Un00C (input reference pulse counter) [pulse]
6 Check the actual number of motor rotation [pulse]
by the changed amount before and after the Un003
(rotation angle 1) [pulse] was executed. Refer to 7.1.3 Basic Mode Selection and Operation for
how it is displayed.
Un003 (rotation angle 1) [pulse]
7 Check that steps 5 and 6 satisfy the following equa-
tion:
Un003=Un00C × (Pn202/Pn203) −
8 Check that the motor rotation direction is the same
as the reference. Check the input pulse polarity and input reference
pulse form. Refer to 8.6.1 (2) Setting a Reference
Pulse Form.
9 Input the pulse reference with the large number of
motor rotation from the host controller to obtain the
constant speed.
Set the motor speed of several 100 min -1 for the refer-
ence pulse speed because such speed is safe.
