6.10 Safe Brake Ramp (SBR)
Brake ramp for "Safe Brake Ramp" without encoder
p9581/p9381 (SI Motion braking ramp reference value, Control Unit/Motor Module) and
p9583/p9383 (SI Motion brake ramp monitoring time, Control Unit/Motor Module) are used to
set the steepness of the brake ramp. Parameters p9581/p9381 determine the reference
speed and parameters p9583/p9383 define the monitoring period. Parameters p9582/p9382
are used to set the time which passes after the triggering of Safe Stop 1, selection of SLS or
SLS level changeover and the start of brake ramp monitoring.
