Description
Defines the shape of the ramp.
0.0 s: Linear ramp. Suitable for steady acceleration or
deceleration and for slow ramps.
0.1...1000.0 s: S-curve ramp. S-curve ramps are ideal for
lifting applications. The S-curve consists of symmetrical
curves at both ends of the ramp and a linear part in
between.

Settings and signals for the DC voltage controller.
See the diagrams in chapter
logic diagrams (page 201).
Selects the voltage used for voltage error calculation if the
converter voltage controller controls the converter DC bus
voltage or the energy storage DC voltage. See the diagram
DC voltage controller on page 203.
DC bus voltage.
Energy storage voltage.
Displays the filtered voltage error between reference and
actual measured value. See the diagram
controller on page 203.
This parameter is read-only.
