Digital Reference Adapter Board
The Digital Reference Adapter Board is connected to Microbus Port A
with wiring to external devices at terminals 23 to 62 of TB3.
The drive is shipped pre-configured, meaning that all of the inputs and
outputs are linked to a predefined signal.
Figure 6.23 shows the 1395 standard configuration for the Digital
Reference Adapter Board. The drive has the flexibility to be reconfigured
for the application or as required.
24VDC Connection – A properly sized 24VDC power supply is required
to power the 24 volt inputs.
Digital Reference Input – The Digital Reference Adapter Board contains
one digital reference command for the drive. The board is set up by default
for the encoder input signal to be single channel, dual edge (i.e. both the
rising and falling edges are used by the counting logic). The hardware is
configured for +5VDC signal inputs with jumpers J6 and J7 in the 1 – 2
position. For a +12VDC signal the jumpers must be placed in the 2 – 3
position.
ATTENTION: To guard against possible component damage,
ensure that jumpers are positioned correctly.

Figure 6.22 shows the typical encoder connection used as a signal for the
digital reference input. This encoder can be machine mounted or mounted
on the motor of the lead section.
