4.3.3 Trial Operation under Position Control (Analog Voltage Reference) from the
Host Controller with the SERVOPACK Used for Speed Control
To operate the SERVOPACK in speed control (analog voltage reference) 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 Control (Analog Voltage Reference) .
Step Operation Reference
1
Recheck the power supply and the input signal circuits, and turn ON the SERVO-
PACK control power supply.

4 Turn ON the main circuit power supply of the SERVOPACK. −

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.

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.
