Using a Control Unit, control is possible either via PROFIsafe or TM54F. Mixed operation is
not permissible.

Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
● They are kept separate for each monitoring channel.
● During startup, checksum calculations (Cyclic Redundancy Check, CRC) are performed
● Data storage: The parameters are stored on the non-volatile memory card.
● Factory settings for Safety parameters
● They are password-protected against accidental or unauthorized changes.
Checking the checksum
For each monitoring channel, the Safety parameters include one parameter for the actual
checksum for the Safety parameters that have undergone a checksum check.
During commissioning, the actual checksum must be transferred to the corresponding
parameter for the reference checksum. This can be done for all checksums of a drive object
at the same time with parameter p9701.
Basic Functions
● r9798 SI actual checksum SI parameters (Control Unit)
● p9799 SI reference checksum SI parameters (Control Unit)

on the Safety parameter data and checked. The display parameters are not contained in
the CRC.
– A reset of the safety parameters to the factory setting on a drive-specific basis using
p3900 and p0010 = 30 is only possible when the safety functions are not enabled
(p9301 = p9501 = p9601 = p9801 = p10010 = 0).
– The Safety parameters can be reset to the factory setting with p0970 = 5. To do so,
the Safety Integrated password must be set. When Safety Integrated is enabled, this
can result in faults, which in turn require an acceptance test to be performed. Then
save the parameters and carry out a POWER ON.
– A complete reset of all parameters to the factory settings (p0976 = 1 and p0009 = 30
on the Control Unit) is possible even when the safety functions are enabled (p9301 =
p9501 = p9601 = p9801 = p10010 ≠ 0).
