A-12 Interconnect Diagrams
The example below shows 1394 (Series A and B) axis modules (no
internal brake or thermal switch filter). Separate 24V dc isolation
power supply and relay (CR2) are recommended. Using this start/stop
string configuration all axes are disabled when any one motor faults.
Figure A.11
Isolated Series Start/Stop String
1 120V ac (50/60 Hz) power may be used in place of 24V dc for motor thermal switch circuits in Series A and B axis
modules.
Note: Refer to Figure 1.3 for the location of the TB1/TB2 connectors
and pin-out diagram.
