9 When the ramp reaches the target value, it stops (RampActive = False) and
the internal timer starts.
10 If the target value changes, the timer is reset, and RampActive = True during
the change.
11 When the timer has run uninterrupted for a period equal to the time defined
by the parameter TimerTime, the highlighted segment is turned Off
(RampDone = True).
Notes:
• The values of the outputs RampActive and RampDone change according to the
text above. On the lines where there is no text enclosed in parenthesis, the value
of these outputs remain unchanged.
• Changing the controller mode from Auto to non-Auto when the ramp is active
terminates the ramp and freezes the Set Point at the current value. At the same
time RampActive is set to False, and RampDone is set to True.
Advanced Set Point Ramp
The Advanced Set Point Ramp function is only available on the ECA600 and
EMA60 controllers.
The Advanced Set Point Ramp block has two digital outputs, RampDone and
Ramp Active. The block holds nine parameters, RampMode, TimeUnit,
RampSpeed, RampStart and StartValue, and five Time and Va lu e parameters.
The Advanced Set Point Ramp works as follows:
1 The Control Mode is non-Auto (usually Manual) (RampActive = False,
RampDone = True).
2 The Control Mode is changed to Auto (RampActive = True,
RampDone = False).
3 The Set Point is set to the value of the Process Value, or set to the value of
the StartValue parameter depending on the setting of the setting of the
RampStart parameter.
4 If the Advanced Set Point Ramp is configured to start from the Process
Value, the rate of change of the Set Point is the same as the one defined by
the StartValue and the first Breaking Point.
