Breaking cam

Definition

A Braking type is one that changes to 1 when a threshold is crossed and returns to 0 when the same threshold is crossed in the opposite direction.

It is characterized by:

a forward threshold value X1 (value of the angle which sets the brake when the threshold is crossed in the forward direction)
a reverse threshold value X2 (value of the angle which sets the brake when the threshold is crossed in the reverse direction)
an activation type: forward/reverse, forward or reverse activation type.

Threshold X1 can be greater than X2 (it is thus possible to set the brake cam either in the or between 2 cycles).

NOTE: The confirmation condition must be at state 1 so that the cam changes to 1 when the threshold is crossed. If the confirmation condition changes to 0, the brake is engaged.

Operation

This table describes the performance of a braking cam.

Activation type	Description	Illustration
Forward	The brake is activated when threshold X1 is crossed in the forward direction. The brake is deactivated when threshold X1 is crossed in the reverse direction.
Reverse	The brake is activated when threshold X2 is crossed in the reverse direction. The brake is deactivated when threshold X2 is crossed in the forward direction.
Forward and reverse	The brake is activated when: Threshold X1 is crossed in the forward direction. Threshold X2 is crossed in the reverse direction. The brake is deactivated when these thresholds are crossed in the opposite direction
