Step
1
Check the power and input signal circuits again, and
check that the speed reference input (voltage
between the V-REF and SG) is 0 V.
2 Turn ON the servo ON (/S-ON) input signal.
3 Generally increase the speed reference input voltage
between V-REF and SG from 0 V.
4 Check the speed reference input to the
SERVOPACK (Un000 [mm/s]).
5 Check the Un000 (motor speed [mm/s].
6 Check that the Un001 and Un000 values in steps 4
and 5 are equal.
7 Check the speed reference input gain and motor
movement direction.
8 When the speed reference input is set to 0 V and
servo OFF status enters, the trial operation for ser-
vomotor without load is completed.

Check Method and Remarks
Refer to the above figure for input signal circuit.
If the linear servomotor moves with the speed refer-
ence input 0V, refer to 9.7.3 Adjusting Offset, and use
the reference voltage offset to keep the linear servomo-
tor from moving.
The factory setting is 6 V/rated speed.
Refer to 8.1.3 Basic Mode Selection and Operation for
how it is displayed.
Refer to 8.1.3 Basic Mode Selection and Operation for
how it is displayed.
Change the speed reference input voltage and check
that Un001 and Un000 values are equal for multiple
speed references.
Refer to the following equation to change the Pn300
(speed reference input gain).
Un001=(voltage between V-REF) [V] × Pn300 [rated
speed/6V]
To change the motor movement direction without
changing polarity for speed reference input gain, refer
to 9.6.2 Switching the Linear Servomotor Movement
Direction.
Perform the operation from step 2 again after the
motor rotation direction is changed.
