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
on the Safety parameter data and checked. The display parameters are not contained in
the CRC.
● Data storage: The parameters will be saved in the non-volatile memory.
● Factory settings for Safety parameters
– 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).
– 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 error messages, 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 ≠ 0).
● The Safety parameterization is password-protected against accidental or unauthorized
changes.
NOTICE
The following Safety parameters are not protected by the Safety password:
• p9370 SI Motion acceptance test mode (CPU 2)
• p9570 SI Motion acceptance test mode (CPU 1)
• p9533 SI Motion SLS Setpoint speed limitation
• p9783 SI Motion Synchronous motor current without encoder
