2.2 List of parameters
Note: SDI: Safe Direction (safe motion direction)
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
For bit 00:
For bit = 1 and with the SSM safety function activated, the following applies:
- During pulse suppression, monitoring is switched off and the feedback signal has a 0 signal level.
For bit = 0 and with the SSM safety function activated, the following applies:
- Monitoring continues during pulse suppression. The feedback signal last displayed before pulse suppression is kept
and the system goes into the STO state.
For bit 08:
For bit = 1 and with the SDI safety function activated, the following applies:
- During pulse suppression, monitoring is switched off and the status signal indicates inactive.
For bit = 0 and with the SDI safety function activated, the following applies:
- Monitoring continues during pulse suppression. The status signal indicates active and the system goes into the STO
state.

Description: Sets the behavior of safety functions and their feedback during pulse suppression in encoderless operation.
Bit field: Bit
00
08
Dependency: Refer to: C01711
Notice: For bit 00:
If the OFF1 or the OFF3 ramp-down time is too low, or there is an insufficient clearance between the SSM limit
speed, and the shutdown speed, then it is possible that the "speed under limit value" signal does not change to 1,
because no speed actual value below the SSM limit was able to be identified before pulse cancellation. In this case,
the OFF1 or the OFF3 ramp-down time or the clearance between the SSM limit speed and shutdown speed must be
increased.
