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 output takes over the value set at
U815.3 for as long as "Set" is at U816.5 = 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.
