Unidrive M300/HS30 Quick Start Guide
Issue Number: 7
Defines which value of keypad control mode reference is displayed at power-up.
Defines the mode used by the ramp system.
0:
Fast ramp
1:
Standard ramp
2:
Standard ramp with motor voltage boost
3:
Fast ramp with motor voltage boost
Fast ramp is linear deceleration at programmed rate, normally used when a braking resistor is
installed.
Standard ramp is controlled deceleration to prevent DC bus over-voltage trips, normally used when
there is no braking resistor installed.
If a high motor voltage mode is selected, deceleration rates can be faster for a given inertia but motor
temperatures will be higher.
Setting Pr
29
to 0 allows the user to disable the ramps. This is generally used when the drive is
required to closely follow a speed reference which already contains acceleration and deceleration
ramps.
