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 00.029 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.
* Only a value of 3 or 4 in this parameter is saved.
If Pr 00.030 is equal to 1 or 2, this value is not transferred to the EEPROM or the drive. If Pr 00.030 is
set to a 3 or 4 the value is transferred.
For further information, please refer to Chapter 9 NV Media Card Operation on page 54.
