3.5.56.1 Calculation and setting of the times T
ir
and T

The acceleration time and deceleration time refer to a change of the output value from 0 to 100 %.
The times T
ir
and T

3.5.56.2 Loading of the ramp function generator
The ramp function generator can be initialised with defined values via the inputs RFG1−SET and
RFG1−LOAD.
l As long as the input RFG1−LOAD = HIGH, the input RFG1−SET is switched to the output.
l If the input RFG1−LOAD = LOW, the ramp function generator accelerates/decelerates from this
value to its input value within the set T
i
times.
