Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
● The safety parameters 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 setpoint 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 setpoint checksum SI parameters (Control Unit)
● r9898 SI actual checksum SI parameters (Motor Module)
● p9899 SI setpoint checksum SI parameters (Motor Module)

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
p0970 or p3900 and p0010 = 30 is only possible when the safety functions are not
enabled (p9301 = p9501 = p9601 = p9801 = p10010 = 0).
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).
NOTICE
The following safety parameters are not protected by the safety password:
• p9370 SI Motion acceptance test mode (Motor Module)
• p9570 SI Motion acceptance test mode (Control Unit)
• p9533 SI Motion SLS setpoint speed limitation
