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 During ramp-up, 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 Unit
These parameters are stored on the non-volatile CompactFlash card.
– Safety parameters for Motor Module
These parameters are stored on the non-volatile CompactFlash card in a
separate file and format.
S Factory settings for safety parameters
You can only reset the safety parameters to the factory setting on a
drive-specific basis using p0970 or p3900 when the safety functions are not
enabled (p9601 = p9801 = 0).
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 corre-
sponding parameter for the specified checksum.
S r9798 Safety Integrated actual checksum SI parameters (Control Unit)
S p9799 Safety Integrated setpoint checksum SI parameters (Control Unit)
S r9898 Safety Integrated actual checksum SI parameters (Motor Module)
S p9899 Safety Integrated setpoint checksum SI parameters (Motor Module)
During each ramp-up procedure, the actual checksum is calculated via the safety
parameters and then compared with the specified checksum.
If the actual and specified checksums are different, fault F01650 or F30650 is out-
put and an acceptance test requested.
