r9872.0...24 CO/BO: SI status (Motor Module)
Displays the Safety Integrated status on the Motor Module/Hydraulic Module.
Bit 00: STO selected on Motor Module
1 signal: Yes, 0 signal: No
Bit 01: STO active on Motor Module
1 signal: Yes, 0 signal: No
Bit 02: SS1 delay time active on the Motor Module
1 signal: Yes, 0 signal: No
Bit 03: Safe Brake Adapter feedback signal
1 signal: High, 0 signal: Low
Bit 04: SBC requested
1 signal: Yes, 0 signal: No
Bit 05: SS1 selected on Motor Module
1 signal: Yes, 0 signal: No
Bit 06: SS1 active on Motor Module
1 signal: Yes, 0 signal: No
Bit 07: STO terminal state on the Motor Module (Basic Functions)
1 signal: Yes, 0 signal: No
Bit 09: STOP A cannot be acknowledged, active
1 signal: Yes, 0 signal: No
Bit 10: STOP A active
1 signal: Yes, 0 signal: No
Bit 15: STOP F active
1 signal: Yes, 0 signal: No
Bit 16: STO cause, safety commissioning mode
1 signal: Yes, 0 signal: No
Bit 17: STO cause, selection via terminal
1 signal: Yes, 0 signal: No

If communication is interrupted between the Control Unit and Motor Module (e.g.
by switching-off the Motor Module), then this display parameter is no longer upda‐
ted. The last transferred status of the Motor Module is displayed.
Re bit 00:
When STO is selected, the cause is displayed in bits 16 ... 21.
For bit 05:
When SS1 is selected, the cause is displayed in bits 22 and 23.
For bit 18:
When the bit is set, STO is selected via PROFIsafe.
For bit 22:
This bit indicates via which path SS1 was initiated, i.e. who started the SS1 delay
time. If the SS1 delay time is not started (e.g. because an STO is simultaneously
initiated), then the bit is not set.
