Efficient Networks S120 Safety Integrated basic functions, Set terminals for Safe torque off STO

			Safety Integrated basic functions
			9.7 Commissioning the "STO", "SBC" and "SS1" functions
No.	Parameter		Description/comments
5		Enable "Safe Stop 1" function.
	p9652 > 0	Enable "SS1" on the Control Unit
	p9852 > 0	Enable "SS1" on the Motor Module
		• 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, therefore,
		be identical.
		• The "Safe Stop 1" function is not activated until at least one safety monitoring function
		has been enabled (i.e. p9601 = p9801 ≠ 0).
6		Set terminals for "Safe torque off (STO)".
	p9620 = "Value"	Set the signal source for STO on the Control Unit.
	Terminal "EP"	Wire terminal "EP" (enable pulses) on the Motor Module.
		• Control Unit monitoring channel:
		By appropriately interconnecting BI: p9620 for the individual drives, the following is
		possible:
		–	Selecting/deselecting the STO
		– Grouping the terminals for STO
		• Motor Module monitoring channel:
		By wiring the "EP" terminal accordingly on the individual Motor Modules, the following
		is possible:
		–	Selecting/deselecting the STO
		– Grouping the terminals for STO
		Note:
		The STO terminals must be grouped identically in both monitoring channels.
7		Set F-DI changeover tolerance time.
	p9650 = "Value"	F-DI changeover tolerance time on Control Unit
	p9850 = "Value"	F-DI changeover tolerance time on Motor Module
		• The parameters are not changed until safety commissioning mode has been exited
		(i.e. when p0010 ≠ 95 is set).
		• Due to the different runtimes in the two monitoring channels, an F-DI changeover
		(e.g., selection/deselection of STO) does not take immediate effect. After an F-DI
		changeover, dynamic data is not subject to a data cross-check during this tolerance
		time.
		• Both parameters are included in the crosswise data comparison and must, therefore,
		be identical. A difference of one safety monitoring clock cycle is tolerated for the
		values.
