5.3 Menu 2: Ramps
The pre-ramp frequency or speed reference passes through the ramp block controlled by menu 2 before being used by the drive to produce the basic
output frequency (Open-loop modes), or as an input to the speed controller (Closed-loop vector or Servo modes). The ramp block includes: linear
ramps, an S ramp function for ramped acceleration and deceleration, deceleration ramp control to prevent rises in the DC bus voltage within the drive
that would cause an over-voltage trip if no braking resistor is fitted.
