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

7.5.73.2 Loading of the ramp function generator
The ramp function generator can be initialized with defined values via the inputs RFG1-SET and
RFG1-LOAD.
• As long as the input RFG1-LOAD = HIGH, the input RFG1-SET is switched to the output.
• If the input RFG1-LOAD = LOW, the ramp function generator accelerates from this value to its
input value along the set T
i
times.
