7.4.2 EMERGENCY STOP and connecting-up the I/R module
For an EMERGENCY STOP, all the drives in the drive group are stopped via
terminal 64 (controller inhibit) on the infeed/regenerative feedback module.
The drives brake with the maximum current (this can be configured).
After a certain delay (if, for example, the spindle has also braked and is
stationary), the internal line contactor in the NE module that is used to
electrically isolate it from the power supply, is opened via terminal 48
(DIN EN 60204-1). The connection between terminals NS1, NS2 is opened as
an additional safety measure to prevent the line contactor from re-closing.
The infeed/regenerative feedback module is supplied from the line supply using
a three-conductor cable.
The line contactor integrated in the infeed/regenerative feedback module is
used to isolate the drives from the line supply (an external line contactor is not
required).
