4.3.7 Safe direction - SDI
Safe฀direction฀-฀SDI 4- Sicherheitsfunktion_SDI_Ueber
The฀safety฀function฀"safe฀direction"฀(SDI)฀monitors฀the฀defined฀direction฀
of฀rotation฀of฀the฀drive฀axis฀(clockwise฀or฀anti-clockwise).฀
Sicherheitsfunktion_Sxx_Voraussetzung_S1
Prerequisites฀for฀normal฀operation:฀

Input฀"SS1฀Activate"฀and฀"SS1฀SIL3/Reset":฀"1"฀Signal฀(+24฀VDC)

"Ready"฀output:฀"1"฀Signal฀(+24฀VDC).฀The฀safety฀card฀is฀ready฀for฀op-
eration.

"STO฀Acknowledge"฀output:฀“0”฀Signal
Sicherheitsfunktion_SDI_Voraussetzung

Input฀"SDI฀Pos฀Activate":฀"1"฀Signal฀(+24฀VDC)

Input฀"SDI฀Neg฀Activate":฀"1"฀Signal฀(+24฀VDC)
Sicherheitsfunktion_Sxx_Voraussetzung_SIL3

To฀achieve฀SIL3฀or฀Ple:฀Connect฀the฀output฀"STO฀SIL3"฀to฀servo฀am-
plifier฀terminal฀X4A/฀3.
Sicherheitsfunktion_SDI_Ausloesung
The฀safety฀function฀is฀activated฀via

1/0฀pulse฀edge฀at฀the฀input฀"SDI฀Pos Activate"
or

1/0฀pulse฀edge฀at฀the฀input฀"SDI฀Neg฀Activate"
Sicherheitsfunktion_SDI_Reaktion
Reaction:

SDI฀delay฀time฀starts฀

Once฀the฀SDI฀delay฀time฀has฀elapsed,฀the฀direction฀of฀rotation฀is฀mon-
itored

"SDI฀Acknowledge"฀output:฀"1"฀signal

If฀the฀direction฀of฀rotation฀is฀violated,฀safety฀function฀SS1฀(E-STOP฀
braking฀ramp)฀is฀activated.
