14.1.98.6 Ramp function generator for the main setpoint
The setpoint is now led via a ramp function generator with linear characteristic. The ramp
function generator converts setpoint step-changes at the input into a ramp.
[14-31] Acceleration and deceleration times
t
ir
and t
if
are the desired times for changing between w1 and w2.
S-ramps are possible by selecting S-ramp times.
The t
ir
/t
if
values are converted into the required Ti times according to the following
formula:
Setting and selection of Ti times
Via parameters, you can select 16 different Tir and Tif times each for the ramp function
generator.
The selection is made via the binary coded selection inputs bTI1 ... bTI8:
w1, w2 = change of the main setpoint as a function of t
ir
and t
if
RFG-OUT = output of the ramp function generator
