6.17.12 Emergency stop monitoring
Internal
EMERGENCY STOP
If an internal EMERGENCY STOP is triggered (e.g. due to standstill
monitoring), the MANUALplus 620 switches
the control-is-ready output off (STO.A.G; responsible watchdog reacts after
10 ms at the latest)
the inverter enablings off (STO.B.X; responsible watchdog reacts after the
time set in MP_watchdogTime of 1 to 6 s), and the inverters are now
without power.
An error message appears and the PLC program is stopped. Depending on the
error class, it might be possible that it cannot be cleared with the CE key:
Correct the error and restart the switch-on routine.

Testing an internal
EMERGENCY STOP
For test purposes, an internal EMERGENCY STOP can be simulated in order
to inspect the correct wiring of the machine. The control-is-ready output is
reset, and the NC and PLC are no longer operable.
Under MOD, enter the code number 6871232.
Press the ENT key and the test will start.
After the test has been completed, you must restart MANUALplus 620.
It is essential that you support hanging axes before the test in order to
prevent damage to the machine in case of error.
