2.7.4.7 Additional setpoint

 Via nNAdd_a you can combine an additional setpoint (e.g. a correction signal) with the main

setpoint.

 Via bNAddInv_b you can invert the input signal, before it is applied to the ramp generator. The

ramp generator has a linear characteristic. Its T

−times are set with dnTirAdd (ramp−up time)

and dnTifAdd (ramp−down time).

 If bLoad_b = TRUE, the ramp generator is set to 0 and held there, without considering the

−times. The same applies when controller inhibit (CINH) is set.
