Cam controller with compensation for switching delays
104
8.4.15 Cam controller with compensation for switching delays
With the function "Cam controller", you can switch 4 actuators (switch elements)
dependent on position.
♦
The switching positions are fixed positions within the positioning range.
♦
The reference value for the switching positions can be selected from:
the position actual value (S1) or
the position set point or
the absolute value (S12)
♦
The switching delay of the actuators is compensated for dependent on the speed.
Outputs O9 ... O12
Parametrization occurs via variables in the range V50 ... V70.

* The switching processes described apply for increasing setpoint and P215=0;
with decreasing setpoint switch off occurs at the same position where switch on
previously occured.
