Table 6.14.4.1: Ramp selection
In order to activate the Multiramp function, it must be enabled with the Enab multi rmp parameter.
The ramp required is selected via the Ramp sel 0 and Ramp sel 1 signals. When the selection is made via the
terminal strip, it is possible to select only one digital input. This configuration enables only the ramp time selected.
Another ramp can be selected at any time. If this happens during an acceleration or deceleration phase, the refer-
ence value will then follow the new ramp. The ramp parameter are defined via the keypad or serial line.
