Bit field: Bit Signal name
00 SSM during pulse suppression and sensor-
less
08 SDI during pulse suppression and sensor-
less
Dependency: Refer to: C01711
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.

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 Con-
trol 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.
- 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: p9300, p9511
Refer to: F01652
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 (p9601.2 = 1).
The monitoring clock cycle from p9500 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 value for the parameter must also be greater than or equal to 2
ms.
A change only becomes effective after a POWER ON.
