time is either 100 µs or 125 µs, depending on
the eldbus cycle time.

Sample time is either 200 µs or 250 µs,
depending on the eldbus cycle time.

6.5.4.25 DD_BrakeHandling_ISD51x
This function block overwrites the status of the brake. The
brake is controlled automatically by the axis, however it
can be force lifted or engaged with this function block (for
example, to move the shaft of the axis manually). The
brake is a holding brake and is not intended to be used in
normal operation.
The manipulation of the brake can take some time and is
not applied to the axis immediately.

VAR_INPUT
Execute BOOL FALSE Overwrites the brake state
at rising edge.
Lift BOOL FALSE TRUE: Overwrite the brake
automatic and lift it.
FALSE: Overwrite the brake
automatic and release it.
VAR_OUTPUT
Done BOOL The brake has successfully
been modied.
Busy BOOL The function block is not
nished and new output
values are to be expected.

6.5.4.26 DD_SelectControlParamSet_ISD51x
This function block selects the used control parameter set
of the axis. If Enable is TRUE, the input Set is evaluated. If
the input Enable is FALSE, the last value is used. This
function block only works if the control is not overwritten
by CAM mode (see chapter 6.5.6.2 MC_CamIn_ISD51x).
The manipulation of the control parameter set takes eect
with the next network communication cycle.
