"Simultaneously" means:
The changeover must be complete in both monitoring channels within the parameterized
tolerance time.
● p9650 SI tolerance time F-DI changeover (Control Unit)
● p9850 SI tolerance time F-DI changeover (Motor Module)
If the "Safe Torque Off" function is not selected/deselected within the tolerance time, this is
detected by the crosswise comparison, and fault F01611 or F30611 (STOP F) is output. In
this case, the pulses have already been canceled as a result of the selection of "Safe Torque
Off" on one channel.

General information about commissioning safety functions
Commissioning notes
NOTICE
For safety reasons, safety functions cannot be commissioned offline with the STARTER
commissioning tool (or SCOUT).
Note
•
The "STO", "SBC" and "SS1" functions are drive specific, that is, the functions must be
commissioned individually for each drive.
•
To support the "STO" and "SBC" functions, the following (minimum) safety versions are
required:
Control Unit: V02.01.01 (r9770[0...2])
Motor Module: V02.01.01 (r9870[0...2])
•
To support the "SS1" functions, the following (minimum) safety version is required:
Control Unit: V02.04.01 (r9770[0...2])
Motor Module: V02.04.01 (r9870[0...2])
•
If the version in the Motor Module is incompatible, the Control Unit responds as follows
during the switchover to safety commissioning mode (p0010 = 95):
– Fault F01655 (SI CU: Align the monitoring functions) is output. The fault triggers fault
reaction OFF2.
The fault cannot be acknowledged until safety commissioning mode (p0010 ≠ 95) is
exited.
– The Control Unit triggers a safe pulse suppression via its own safety switch-off signal
path.
– If parameterized (p1215), the motor holding brake is applied.
– The safety functions cannot be enabled (p9601/p9801 and p9602/p9802).
