9.3.2 Operating Procedure in Speed Control Mode (Pn000 = n. †† 0 † )
The following circuit is required: External input signal circuit or equivalent.
Step Description Check Method and Remarks
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. Refer to the above figure for input signal circuit.
2 Turn ON the servo ON (/S-ON) input signal. 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.
3 Generally increase the speed reference input voltage
between V-REF and SG from 0 V. The factory setting is 6 V/rated speed.
4 Check the speed reference input to the SERVO-
PACK (Un000 [mm/s]). Refer to 8.1.3 Basic Mode Selection and Operation for
how it is displayed.
5 Check the Un000 (motor speed [mm/s]. Refer to 8.1.3 Basic Mode Selection and Operation for
how it is displayed.
6 Check that the Un001 and Un000 values in steps 4
and 5 are equal. Change the speed reference input voltage and check
that Un001 and Un000 values are equal for multiple
speed references.
7 Check the speed reference input gain and motor
movement direction. 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 movement direction is changed.
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. −
