Name Type DIS DIS format CFG List Lenze
BRK−SET d C0459 bin C0451 2 1000 −
BRK−NX a C0458/1 dec [%] C0450 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.
BRK−SIGN a C0458/2 dec [%] C0452 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.
BRK−M−SET a − dec [%] C0244 − 0.00 Holding torque of the DC injection brake

BRK−T−ACT a − dec C0195 − 99.9 Brake application time
BRK−T−RELEASE a − dec C0196 − 0.0 Brake release time
Function
The signals N−ACT, M−ACT, N−SET and BRK−Nx are processed as absolute values within the function
block.
