Sicherheitsfunktion_Legende_SSR_S1  SS1 Activate: Input for safety function SS1
 SS1 SIL3/Reset: Input for SIL3 and reset
 SSR Activate: Input for safety function SLS
 Ready: Output for operating status of the safety card
 STO Acknowledge: Output for feedback from safety function STO
 SRA Acknowledge: Output for monitoring the limit value on the motor
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.
