Note for users:
The block can be used, for example, for
continuously and hence smoothly changing
the transmission ratio of the gear function.
The ramp generator ouput takes over the value set at
U469.3 for as long as "Set" is at U470.5 = 1.
Y is always kept within the value range between the
lower and upper limits. If during "Enable motor
potentiometer" both signals MOP+ and MOP- are 1
simultaneously, output y remains unchanged.
