4.3.3 Trial Operation under Position Control from the Host Controller with the
SERVOPACK Used for Speed Control
To operate the SERVOPACK in speed control under the position control from the host controller, check the
operation of the servomotor after finishing the trial operation explained in 4.3.2 Trial Operation in Speed Con-
trol
.
Step Operation Reference
1
Recheck the power supply and the input signal circuits, and turn ON the control
power supply of the SERVOPACK and converter.

4 Turn ON the main circuit power supply of the SERVOPACK and converter. −
5
Check that speed reference input (the voltage between V-REF and SG) is 0 V, and
turn ON the servo ON (/S-ON) input signal.
Note: If the servomotor rotates at a very low speed with the speed reference input at
0 V, adjust the reference offset so that the servomotor will not rotate.

Adjustment
6
To check the speed of the servomotor, execute a constant speed reference at a low
speed through the host controller.
Example: Visually check that the servomotor rotates once per second with a speed
reference of 60 min
-1
.
Note: If the speed of the servomotor is not correct, check the reference sent by the
host controller.

To check the rotation of the servomotor, execute a simple positioning reference
through the host controller.
Example: Input a reference that is equivalent to a single rotation of the servomotor.
To confirm that the servomotor moved a single rotation, do a visual check
or check the rotational angle 1 (Un003 [pulse]).
Note: If the rotation of the servomotor is not correct, check the reference sent by the
host controller.
