Based on the voltage applied to the analog speed command (SPR), set up the conversion gain to
motor command speed.
You can set up “slope” of relation between the command input voltage and motor speed, with Pr3.02.
Default is set to Pr3.02=500(r/min)/V, hence input of 6V becomes 3000r/min.
Notice:
1. Do not apply more than ±10V to the speed command input(SPR).
2. When you compose a position loop outside of the driver while you use the driver in velocity
control mode, the setup of Pr3.02 gives larger variance to the overall servo system.
3. Pay an extra attention to oscillation caused by larger setup of Pr3.02.
