Shutdown (Emergency Stop) Signal Only to Drive
Remove the jumper. In this configuration the EMG input of the drive is only
connected to the EMG pin on the Axis I/O screw terminal. The PCI-7390
Axis <1..4> General-Purpose Input 0 can be used for any general-purpose
functionality. The PCI-7390 Axis <1..4> General-Purpose Input 0 signal
can be accessed through the Axis I/O screw terminal. Connect the EMG
switch or signal to the EMG pin on the Axis I/O screw terminal. In this
configuration the shutdown (emergency stop) signal goes only to the drive
and stops only the affected axis. The other axes in the motion control
system are unaffected.
Separate Shutdown (Emergency Stop) Signals to
Controller and Drive
Remove the jumper. In this configuration the EMG input of the drive is only
connected to the EMG pin on the Axis I/O screw terminal. Connect
separate shutdown (emergency stop) switches or signals to the EMG pin
and the PCI-7390 Axis <1..4> General-Purpose Input 0 pin on the Axis I/O
screw terminal. In software, configure the PCI-7390 Axis <1..4>
General-Purpose Input 0 to function as a shutdown (emergency stop) input.
Use the two shutdown (emergency stop) inputs independently as per your
requirements. In this configuration, you configure separate shutdown
(emergency stop) conditions for the drive and for the controller.
CNA and CNB Cable Pin Assignments
Tables B-2 and B-3 show the pin assignments for the CNA and
CNB cables.
Note
These tables are provided for reference for custom cable assembly. For custom
cables, use the 3M 20-pin MDR connector part number 10120-6000EC and 3M MDR
backshell part number 10320-3210-000.
