Motor Position and Speed Responses
For a test without a motor, the following responses are simulated for references from the host
controller according to the gain settings for position or speed control.
• Servomotor position
• Motor speed
• External encoder position
The load model will be for a rigid system with the moment of inertia ratio that is set in Pn103.

Meaning
When an encoder is not connected, start as
SERVOPACK for Rotary Servomotor.
When an encoder is not connected, start as
SERVOPACK for Linear Servomotor.
Setting Unit Default Setting
0.01 μm
