15.2.5 Detailed description of the signals
(1) Speed control mode
(a) Speed setting
1) Speed command and speed
The servo motor is run at the speeds set in the parameters or at the speed set in the applied
voltage of the analog speed command (VC). A relationship between the analog speed command
(VC) applied voltage and the servo motor speed is shown below:
The maximum speed is achieved at 10V. The speed at 10V can be changed using parameter
No. 25.
