56 Function Description
5.5.1

Function Block: Ramp Generator

The speed at which the electrical current follows the setpoint value specification
is designated as the "ramp function". The ramp generator serves, among other
purposes, to protect the slower mechanical systems when the setpoint value is
changed erratically.

Figure 20: Ramp Generator

Four parameterizable ramps are provided for the ramp function, which can
increase or reduce the actual value when the setpoint value is directly specified.
The selection of the active ramp takes place when the setpoint value is entered
into the process image
There are likewise ramps that can be parameterized to switch the dithering on
and off, as well as to increase or reduce the setpoint value in the setup mode.
The gradient of a ramp is defined in relation to the entire range of the setpoint
value. This allows a jumping setpoint value change by 100% of the nominal value
to be divided across a parameterizable time period of up to 10 s.
