SS2 when OPMODE = 0 ... 8
With the drive-activated safety function "safe stop 2" (SS2), the
movement is ultimately continued.
The status of the safety card (SS2 activated) is transmitted to the ser-
vo 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 speed-controlled 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.
