)
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

The number of input reference pulses (Un00C) can be obtained from the following equation.
