7.3 Control of "STO" and "SS1" via terminals on the Control Unit and the Motor/Power Module
7.3.1.2
Simultaneity and tolerance time of the two monitoring channels
Simultaneity and tolerance time of the two monitoring channels
The "Safe Torque Off" function must be selected/deselected simultaneously in both
monitoring channels using the input terminals and is only effective for the associated drive.
1 signal: Deselecting the function
0 signal: Selecting the function
"Simultaneously" means:
The changeover must be complete in both monitoring channels within the parameterized
tolerance time.
● p9650 SI SGE changeover tolerance time (Control Unit)
● p9850 SI SGE changeover tolerance time (Motor Module)
If the "Safe Torque Off" function is not selected/deselected within the tolerance time, this is
detected by the cross-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.
