● 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)
● r9898 SI actual checksum SI parameters (Power Module)
● p9899 SI reference checksum SI parameters (Power Module)
Extended Functions
● r9398[0...1] SI Motion actual checksum SI parameters (Power Module)
● r9399[0...1] SI Motion reference checksum SI parameters (Power Module)
● r9728[0...1] SI Motion actual checksum SI parameters
● p9729[0...1] SI Motion reference checksum SI parameters
During each ramp-up procedure, the actual checksum is calculated via the safety
parameters and then compared with the reference checksum.
If the actual and reference checksums are different, fault F01650/F30650 or F01680/F30680
is output and an acceptance test requested.
Drive functions
Function Manual, 10/2008, 6SL3097-4AB10-0BP0
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 = 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 ≠ 0).
NOTICE
The following safety parameters are not protected by the safety password:
• p9370 SI Motion acceptance test mode (Power Module)
• p9570 SI Motion acceptance test mode (Control Unit)
• p9533 SI Motion SLS Setpoint speed limitation
• p9705 BI: SI Motion Test stop signal source
