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

Caution:
When you compose the servo drive system with this driver set to velocity
control mode and external positioning unit, the motor might perform an abnormal
action if the polarity of the speed command signal from the unit and the polarity of this
parameter setup does not match.
