Monostable cam

Definition l l

A Monostable type cam is one that changes to 1 when a threshold is crossed and returns to 0 after a time delay.

It is characterized by: l a value of threshold X1 expressed in a number of pulses (X1 is between 0 and the number of pulses/cycles)

An M1 time delay expressed in 1/10 ms (0 to 16383, i.e. 1.6383 s max.)

An activation type: forward/reverse, forward or reverse.

Note: l The confirmation condition must be at state 1 for the time delay to be set when l the threshold is crossed. If the confirmation condition changes to 0, the time delay in progress ends normally.

If the time delay is in progress at a new crossing of threshold X1, the time delay is reset with the setpoint value. The output remains at 1.

Operation

Activation type
