2.2 List of parameters
p9311 SI Motion actual value sensing clock cycle (Motor Module) / SI Mtn act clk MM
VECTOR_G Can be changed: C2(95)
Data type: FloatingPoint32
P-Group: Safety Integrated
Not for motor type: -

0.0000 [µs]
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).
Dependency: Refer to: p0115, p9300, p9511
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: The parameter is only active for drive-based motion monitoring functions (p9801.2 = 1).
The monitoring clock cycle from p9300 must be an integer multiple of this parameter.
In the case of motion monitoring functions with encoder, the clock cycle time for actual value sensing must be an
integer multiple of the current controller clock cycle and at least 4 times slower than the current controller clock cycle.
A factor of at least 8 is recommended.
The clock cycle time of the actual value sensing should not be set to more than 8 ms.
A change only becomes effective after a POWER ON.
p9312 Select SI Motion safety functions without selection (MM) / SI Mtn w/o sel MM

Description: Sets the safety functions without selection.
The safety functions without selection are enabled with p9601.5/p9801.5.
Using this parameter, the individual motion monitoring functions can then be selected (e.g. SLS, SDI positive, SDI
negative), which should then be permanently selected.

Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Note: A change becomes immediately effective after exiting the safety commissioning mode.
SDI: Safe Direction (safe motion direction).
