Supported functions

The following Safety Integrated functions (SI functions) are in conformance with
EN 61800–5–2:
S Safety Integrated basic functions
These functions are part of the standard scope of the drive.
– Safe Torque Off (STO)
STO is a safety function that prevents the drive from restarting unexpect-
edly, in accordance with EN 60204–1, Section 5.4.
Note
When a drive object that has Safety Integrated functions released is switched to
"Parking" mode, the Safety Integrated software responds by activating STO
without generating a separate message.
– Safe Stop 1 (SS1, time–controlled)
The SS1 function is based on the "Safe Torque Off" function. This means
that a Category 1 stop in accordance with EN 60204–1 can be implemented.
– Safe Brake Control (SBC)
The SBC function permits the safe control of a holding brake.
SBC is not supported by chassis components.

Properties of Safety Integrated parameters
The following applies to Safety Integrated parameters:
S They are kept separate for each monitoring channel.
S During startup, 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 Establish/restore the factory setting 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).
All the factory settings can be restored (p0976 = 1 and p0009 = 30 on the Con-
trol Unit) even when the safety functions are enabled (p9601 = p9801 0 0).
S They are password–protected against accidental or unauthorized changes.
