CCON.BRAKE control logic

In the factory settings, the control logic is low active,
i.e. the clamping unit/brake is closed for CCON.BRAKE = 0.
The switching output on the VPWP delivers 0 V

With PNU 522:02, the control logic can be inverted.
See Tab. 3/2.

Tab. 3/2: CCON.BRAKE control logic

Note
The CMAX always sets the switching output on the valve to
0 V directly when the task for activating the brake is deĆ
tected (except if the controller is activated at the same
time. See below). The brake then becomes active directly,
even if the drive is still moving or a force has built up.

·

Make sure that the clamping unit/brake allows this
operating state.
