● Factory settings for safety parameters

– A reset of the safety parameters to the factory setting on a drive-specific basis using

– Safety parameters can be reset to the factory setting with p0970 = 5. To do so, the

– A complete reset of all parameters to the factory settings (p0976 = 1 and p0009 = 30

● The safety parameterization is password-protected against accidental or unauthorized

The password protection is only available online.

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 (Motor Module)

● p9899 SI reference checksum SI parameters (Motor Module)

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 differ, fault F01650 or F01680 is output and an

acceptance test requested.
