Based on the voltage applied to the analog speed command (SPR), set up the conversion
gain to motor command speed.
• You can set up a "slope" of the relation between the command input voltage and the
motor speed, with Pr3.02.
• Default is set to Pr3.02=500 [r/min],
hence input of 6V becomes 3000r/min.
Caution
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.
Pay an extra attention to oscillation caused by larger setup of Pr3.02.

Caution
Specify the polarity of the voltage applied to the analog speed command (SPR).
Setup value Motor rotating direction
0 Non-reversal “+Voltage” “Positive direction”, “–Voltage” “Negative direction”
1 Reversal “+Voltage” “Negative direction”, “–Voltage” “Positive direction”
Default of this parameter is 1, and the motor turns to CW with (+) signal, this has
compatibility to existing MINAS series driver.
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.
