Field Wiring
The terminal base provides connections for each axis and for an
external supply to power the FP-QUAD-510 input channels and
field devices.
external supply to power the FP-QUAD-510 input channels and
field devices.
The FP-QUAD-510 accepts two types of encoder signal inputs:
single-ended (TTL) or differential line driver. Figure 2 shows the
typical encoder wiring for differential signal input. Figure 3 shows
the typical encoder wiring for single-ended signal input. Power for
a +5 V encoder is also provided for each axis. If you require other
encoder power voltages, reference an external supply to either the
C terminal or the COM terminal.
