7.4 Trial Operation from the Host Controller for the Servomotor without a Load
7.4.4 Trial Operation for Position Control
12.
Check the reference pulse speed input to the SERVOPACK with the input reference
pulse speed monitor.
• Using the SigmaWin+: Monitor - Monitor - Motion Monitor, Input Reference Pulse Speed
• Using the Panel Operator or Digital Operator: Un007 (Input Reference Pulse Speed Monitor)
The input reference pulse monitor uses the following formula.
• Rotary Servomotor with a 20-bit Encoder
• Linear Servomotors
Input reference pulse speed monitor = Input reference pulse speed [pulses/s] 
Analog
13.
Check the motor speed monitor.
• Using the SigmaWin+: Monitor - Monitor - Motion Monitor, Motor Speed
• Using the Panel Operator or Digital Operator: Un008 (Motor Speed Monitor)
14.
Confirm that the input reference pulse speed and the motor speed (i.e., the values from
steps 12 and 13) are the same.
15.
Stop the pulse reference from the host controller.
16.
Turn OFF the /S-ON (Servo ON) signal from the host controller.
The servo will turn OFF.
This concludes the procedure for trial operation with position control. Proceed to the following
section.
