Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: Re bit 00:
When the function is activated, a safety-relevant acknowledgement (internal event acknowledge) can be performed
by selecting/deselecting STO.
Re bit 01:
When the function is activated, the active setpoint velocity limit (CO: r9733) is set to zero when STOP F is active.
Re bit 02:
This bit defines the type of motor, which the sensorless actual value sensing evaluates.
For bit = 0, the actual velocity is calculated for an induction motor.
For bit = 1, the actual velocity is calculated for a synchronous motor. This value depends on the setting in p0300.
Bit = 0 should be set if no motor is defined (p0300 = 0).
Re bit 03:
When the bit is activated – when selecting function SS1 or activating a STOP B – an SS1E or a STOP B with Stop,
which should be externally initiated, is triggered instead of SS1 with a drive-based braking response. As a
consequence, brake monitoring (SBR, SAM) is deactivated.
SS1E: Safe Stop 1 external (Safe Stop 1 with external stop)
Re bit 05:
This bit defines the type of modulation, which the sensorless actual value sensing evaluates.
For bit = 0, the actual velocity is calculated for space vector modulation.
For bit = 1, the actual velocity is calculated for edge modulation. This value depends on the setting in p1802.

Re 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.
Note: SDI: Safe Direction (safe motion direction)
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
Re 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.
Re 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.
