CAUTION!
Loss of safety function due to lack of monitoring (e.g. SOS, SLS, SDI)
of the drive during operation!
To exclude hazardous situations for the operator (e.g. when the safety gate
is open during setup mode), the drive must be safeguarded via a suitable
monitoring function (e.g. SOS, SLS, SDI). Unmonitored operation is not per­
mitted. This is the only way to guarantee that a hazardous movement is ex­
cluded: when the safety function SS1 is triggered (E­STOP braking ramp)
the drive is switched to an STO state and the brake is engaged when the
safety function SBC is activated.
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 operation.
} "STO Acknowledge" output: “0” Signal
} Output "SBC+/SBC­": "1" Signal (+24 VDC)
} Both outputs are simultaneously set to a "1" Signal: Voltage difference of 24 V between
SBC+ and SBC­.
} To achieve SIL3 or PL e: Connect the output "STO SIL3" to servo amplifier terminal
X4A/ 3.
Safety function is activated through
} Safety function STO or SS1
Non­safety­related control of the brake output SBC+/SBC­:
} Motor is switched off or "DISABLED" (when actively connected to the servo amplifier's
brake signal)
Reaction:
} Output "SBC+/SBC­": "0" Signal (0 VDC)
} Both outputs are simultaneously set to a "0" Signal: Voltage difference of 0 V between
SBC+ and SBC­.
Diagnostics:
} See section 4.2.2.3, Output test
