SS2 when OPMODE = 0 ... 8
} With the drive­activated safety function "safe stop 2" (SS2), the movement is ultimately
continued.
} The status of the safety card (SS2 activated) is transmitted to the servo amplifier. As a
result, the information is available to a higher level control system (status word).
} The transfer of setpoint values from external servo amplifier interfaces (bus system or
analogue input) is disabled.
} The servo amplifier applies speed­controlled braking with the preset braking ramp until
standstill is achieved.
This status is maintained for as long as safety function SS2 is active.
} If safety function SS2 is deactivated, the status word is updated.
} The servo amplifier automatically switches to the OPMODE that was originally set.
} The transfer of setpoint values from external servo amplifier interfaces (bus system or
analogue input) is once again permitted.
} When OPMODE = 8, the existing motion block can be continued via the "CONTINUE"
command.
