2.4.13.1 Close brake
Function procedure
1. The function is activated using BRK1−SET = HIGH.
– At the same time, BRK1−QSP is set to HIGH. You can use this signal to decelerate the drive
to zero speed via a deceleration ramp.
2. If the setpoint speed exceeds the value at BRK1−Nx, BRK1−OUT = HIGH.
– Invert the signal at the digital output if you need a protection against wire breakage (e. g. via
C0118).
3. A time element is triggered when BRK1−OUT = HIGH. After the time set under C0195 has
elapsed, BRK1−CINH is set to HIGH.
– This signal is used to set controller inhibit (inside the controller). In general, the brake close
time is set here. This is necessary because the brake does not engage immediately when
BRK1−OUT = HIGH and the drive must therefore provide a holding torque for the time set.
