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.
