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.

10

Check the reference pulse speed input to the SER-
VOPACK using the Un007 (input reference pulse
speed) [min

-1

].

Refer to 7.1.3 Basic Mode Selection and Operation for
how it is displayed.
Un007 (input reference pulse speed) [min

-1

]

The number of Un007 (input reference pulses) can be obtained from the following equation.

* The encoder pulse differs depending on the model of the servomotor used.

11

Check the motor speed using the Un000 (motor
speed) [min

-1

].

Refer to 7.1.3 Basic Mode Selection and Operation for
how it is displayed.
