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 thedriver in velocity control mode, the setup of Pr3.02 gives larger varianceto the overall servo system.Pay an extra attention to oscillation caused by larger setup of Pr3.02.3000Speed (r/min)–3000Slope at ex-factory–10 –62 4 6 8 10Positive directionNegative directionCommand input voltage (V)Pr3.03 Title Reversal of speed command input Relatedcontrol mode P S T FRange 0 to 1 Unit — Default 1NoteCautionSpecify the polarity of the voltage applied to the analog speed command (SPR).Setup value Motor rotating direction0 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 hascompatibility to existing MINAS series driver.When you compose the servo drive system with this driver set to velocity control modeand external positioning unit, the motor might perform an abnormal action if the polarity ofthe speed command signal from the unit and the polarity of this parameter setup does notmatch.1.
