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

nal Connections in Speed
Control
2 Adjust the speed reference input gain (Pn300).
5.3.1 Basic Settings for
Speed Control
3 Set the number of dividing pulses (Pn212).
5.3.7 Encoder Output
Pulse Setting
4 Turn ON the main circuit power supply.
5
Check that speed reference input (the voltage between V-REF and SG) is 0V, 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.
5.3.2 Reference Offset
Adjustment
6
To check the speed of the servomotor, execute a constant speed reference through the
host. Check the speed of the servomotor.
Example: Visually check that the servomotor rotates once per second with a speed
reference of 60 min
-1
.
If the speed of the servomotor is not correct, apply forward and reverse rotation refer-
ences, and check the rotation directions.

7
To check the rotation of the servomotor, execute a simple positioning reference
through the host.
Input a reference equivalent to a single rotation of the servomotor and visually check
with the motor rotation angle monitor (Un003 pulses) that the motor axis rotates
once.
If the servomotor rotation is not correct, apply forward and reverse rotation refer-
ences, and check the rotation.

8 Return the speed reference input to 0V.
9 Turn OFF the servo ON (/S_ON) signal.
