4.7 Commissioning the STO, SBC and SS1 functions
Enable Safe Torque Off function
STO via Control Unit terminals
STO via Motor Module terminals
S The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 ≠ 95 is set).
Both parameters are included in the crosswise data comparison and must,
S
therefore, be identical.
Enables the safe brake control function
Enables SBC on the Control Unit
Enables SBC on the Motor Module
The parameters are not changed until safety commissioning mode has
S
been exited (i.e. when p0010 ≠ 95 is set).
S Both parameters are included in the crosswise data comparison and must,
therefore, be identical.
S The safe brake control function only becomes active if at least one safety
monitoring function is enabled (i.e. p9601 = p9801 ≠ 0).
Enable Safe Stop 1 function
Enable SS1 on the Control Unit
Enable SS1 on the Motor Module
S The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 ≠ 95 is set).
Both parameters are included in the crosswise data comparison and must,
S
therefore, be identical.
S The Safe Stop 1 function only becomes active if at least one safety moni-
toring function is enabled (i.e. p9601 = p9801 ≠ 0).
Set terminals for Safe Torque Off (STO)
Set the signal source for STO on the Control Unit
Wire terminal "EP" (enable pulses) on the Motor Module.
Control Unit monitoring channel:
S
By appropriately interconnecting BI: p9620 for the individual drives, the
following is possible:
-- Selecting/deselecting STO
-- Grouping the terminals for STO
Digital input DI 0 ... DI 7 on the Control Unit can be used as a signal source
(NCU). DI 0 ... DI 3 (NX).
Motor Module monitoring channel:
S
By wiring the "EP" terminal accordingly on the individual Motor Modules, the
following is possible:
-- Selecting/deselecting STO
-- Grouping the terminals for STO
Note:
The STO terminals must be grouped identically in both monitoring channels.
