4.7 Executing the SP Ramp Function (limiting the SP
change rate)
With the SP ramp function, the controller operates according to the value
(set point during SP ramp) limited by a change rate. The interval in which
the set point during SP ramp is limited is referred to as the SP ramp".

The change rate during SP ramp is specified by the SP ramp set value"
parameter. The SP ramp set value" default is OFF", and the SP ramp
function is disabled.
Changing of the ramp set point can be monitored in the set point during
SP ramp" parameter (operation level). Use this parameter during moniĆ
toring of the SP ramp.
Operation is the same also during switching of the set points by multi-SP.
