Figure 6-2 Sequence for "Safe Stop 1" without encoder
Braking ramp for "Safe Stop 1" without encoder
p9581/p9381 and p9583/p9383 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 between the
triggering of Safe Stop 1 and the start of brake ramp monitoring.
Restrictions
For the restrictions on "Safe Stop 1" without encoder, see section
→ "Safety Integrated Extended Functions" / Safety Functions "with encoder"/"without
encoder"
