Safety Functions Integrated in the Drive
4.1 General information about SINAMICS Safety Integrated
Monitoring clock cycle integrated in the drive
The safety-relevant drive functions are executed cyclically in the monitoring clock
cycle.
The monitoring clock cycle integrated in the drive is as a minimum 4 ms. Increas-
ing the basic DRIVE-CLiQ sampling time (p0110) also increases the monitoring
clock cycle integrated in the drive.

Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
S They are kept separate for each monitoring channel.
S They are password-protected against accidental or unauthorized changes.
S When booting, a checksum (cyclic redundancy check: CRC) is generated and
checked via the safety parameters, which have undergone a checksum check.
S Data management
– Safety parameters for Control Units and Motor Modules
These parameters are stored on the non-volatile CompactFlash card.
S Establish/restore the factory setting for safety parameters
You can only reset the safety parameters to the factory setting on a drive-spe-
cific basis using p0970 or p3900 when the safety functions are not enabled
(p9601 = p9801 = 0).
S All the factory settings can be restored (p0976 = 1 and p0009 = 1 on the Con-
trol Unit) even when the safety functions are enabled (p9601 = p9801 = 1).
