Description: Sets the behavior of safety functions and their feedback during pulse suppression in encoderless operation.
Dependency: Refer to: C01711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
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.
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 clock cycle time of the actual value sensing for safe motion monitoring.
Setting criteria if the motion monitoring functions are executed with an encoder.
- a slower clock cycle time reduces the maximum permissible velocity - however, it ensures a lower load of the
Control Unit for safe actual value sensing.
- the maximum permissible velocity which, when exceeded, can mean that errors occur during safe actual value
sensing, is displayed in r9730.
- the isochronous PROFIBUS clock cycle is used as a clock cycle time for actual value sensing with a setting of 0 ms;
the setting is 1 ms if isochronous operation is not being used.
Setting criteria if the motion monitoring functions are executed without an encoder:
- the actual value sensing clock cycle must be set to the same value as the current controller clock cycle (p0115).
For SINAMICS S120M, the following applies:
Only setting p9311 = 0 or 2 ms is possible (a value of 0 is internally assumed to be 2).
