Functional features of "Safe Stop 1" with encoder
● The delay time starts after the function is selected. If SS1 is deselected again within this
● The selection is realized through two channels - however braking along the OFF3 ramp,
● The "Safe Acceleration Monitor" (SBR) function is activated when braking (see "Safe
Note
Activating SS1 can mean that the device (PLC, motion controller) which issues the speed
setpoint interrupts the ramp function with OFF2.
The reason is a fault response of this device, which is initiated due to the activation of OFF3.
The fault response can be prevented using suitable parameterization or wiring, which then
signals the initiation of SS1 to this device.
Note
If you use SS1 under EPOS, then an OFF2 is not permitted as fault response to a following
error.

Note
When "Safe Stop 1" (SS1) is installed, the function "Safe Acceleration Monitor" (SBR) is
active. For assigning parameters to the "Safe Acceleration Monitor" (SBR) function
→ see section " Safe Acceleration Monitor" (SBR).
The delay time is set by entering parameters p9356 and p9556. The delay time until the
pulses are suppressed can be shortened by defining a shutdown speed in p9360 and p9560.
To enable the drive to decelerate to standstill, the time set in p9356/p9556 must be sufficient
to allow the drive to decelerate to below the shutdown speed in p9360/p9560 with the OFF3
ramp (p1135).
The shutdown speed defined in p9360/p9560 must be set in such a way that personal safety
or the safety of the machine is not compromised as of this speed and as a result of
subsequent coasting due to the pulses being suppressed.
