1) The values are specified in the process value unit - e.g. [°C, °F, bar, %, etc.]
2) The rate of change must be specified in units/minute (e.g. °C/min) r see gradient control page 261.
3) % specifications are related to measuring range
Xn100 - Xn0. There is no relation to values W0 and W100.
4) As default, value Ymin is set to 0. In this case, output Y1 cannot switch!
5) (
1...6) refers to the six parameter sets of CONTR+ (e.g. Xp1, Xp2, Xp3...Xp6).
