nIn_a Integer analog VAR_INPUT Input
nSet_a Integer analog VAR_INPUT Start value for the ramp generator. The ramp is
initiated by bLoad_b = TRUE.
bLoad_b Bool binary VAR_INPUT TRUE = takes the value at nSet_a and outputs this at
nOut_a; nDeltaOut_a remains at 0 %.
nOut_a Integer analog VAR_OUTPUT The signal is limited to ±100 %. (100 % = 16384)
nDeltaOut_a Integer analog VAR_OUTPUT
·
Provides the acceleration of the ramp generator.
·
The signal is limited to ±100 %.
dwTi Unsigned Long VAR CONSTANT RETAIN Acceleration in [%] (100 % = 16384)
