Unidrive M300/HS30 Quick Start Guide 37
Issue Number: 6
Defines how the motor is controlled when the run signal is removed from the drive.
See the Drive User Guide for further information.
Set to 1 to enable Dynamic V to F mode.
0: Fixed linear voltage to frequency ratio (constant torque - standard load)
1: Voltage to frequency ratio dependant on load current. This gives a higher motor efficiency.
If the drive is to be configured in fixed boost mode (Pr 00.041 = Fd or SrE) with catch a spinning
motor software enabled, an autotune (see Pr 00.038 on page 40) must be carried out to measure the
motor's stator resistance beforehand. If a stator resistance is not measured, the drive may trip on 0 V
or OI.AC while trying to catch a spinning motor.
