12.6.8 Ramp function
The ramp function enables the setpoint value to be continually changed up to the ramp end
value (active setpoint value).
A tolerance band can be set around the setpoint value curve to monitor the actual value. If the
actual value deviates from the tolerance band, a digital signal (tolerance band signal) is acti-
vated.
