Function
The signals N-ACT, M-ACT, N-SET and BRK-Nx are processed as absolute values within the function
block.

Applying the brake

Purpose A HIGH-Signal at the BRK-SET input
activates the function. The BRK-QSP
output is simultaneously set to HIGH.
This signal can be used to decelerate
the drive to zero speed via a
deceleration ramp.
Function If the setpoint speed falls below the
value set at the BRK-Nx input, the
BRK-OUT output is set to HIGH. In order
to ensure a fail-safe design this signal
must be inverted at the output (e.g. via
C0118).

1 1000 Speed threshold from which the drive may
output the signal "Close brake". The signal
source for this input can be a control code,
a fixed value, or any other analog FB
output.
1 1000 Direction of the torque with which the drive
is to set up a torque against the brake. The
signal source for this input can be a control
code, a fixed value, or any other FB output.
