ON FREQUENCY
Range: 0.0 to 500.0 Hz
The output electrical frequency at which the external motor brake is released.
OFF FREQUENCY
Range: 0.0 to 500.0 Hz
The output electrical frequency at which the external motor brake is applied.
ON HOLD TIME
Range: 0.00 to 60.00 s
Sets the duration of the pulse output on HOLD when RELEASE becomes TRUE.
OFF HOLD TIME
Range: 0.00 to 60.00 s
Sets the duration of the pulse output on HOLD when RELEASE becomes FALSE.
RELEASE
Range: FALSE / TRUE
Boolean output providing a signal to operate the brake delay. Note RELEASE is forced
FALSE if the drive is not in Run mode, or if Autotune, Flycatching or Injection Braking are
