Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
S They are kept separate for each monitoring channel.
S At power up, a checksum (Cyclic Redundancy Check, CRC) over the Safety
parameters is generated and checked. The display parameters are not
contained in the CRC.
S Data storage: The parameters are stored on the non--volatile CompactFlash
card.
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 ena-
bled (p9601 = p9801 = 0).
-- All the factory settings can be restored (p0976 = 1 and p0009 = 30 on
the Control Unit) even when the safety functions are enabled (p9601 =
p9801×≠ 0).
S They are password--protected against accidental or unauthorized changes.
Note
The following safety parameters are not protected by the safety password:
S p9370 SI Motion acceptance test mode (Motor Module)
S p9570 SI Motion acceptance test mode (Control Unit)
