Note that the connections described in
Table 1
work only when the encoder has an internal pull-up resistor on the
open collector. Alternatively, it might be preferable to pull the + channel high, and attach the open collector to the -
channel. For example, if using Channel A, A+ on the option board would be tied to VDC, and A- would be connected
to the open collector coming from the encoder. The advantage in this method is that no pull-up/down resistors are
needed; if the encoder has an internal pull-up, this does not affect anything.

DI-E
115 VAC logic input; connect input to 115 VAC to activate.
The programmable functionality of these inputs is controlled by
parameters 728, 729, 730, 731, and 732. Each of these inputs can be
disabled or configured to emulate the function of the FWD, REV, R/J, EN,
MOL, DI1, DI2, DI3, DI4, or DI5 input terminals on the X5 control board.
Refer to the X5 User’s Manual for more information (DPD 00089).

NO3
RC3
NC3
The third auxiliary relay.
The function of this relay is set by parameter 709. Functionally, it is
capable of each of the features outlined in the X5 user manual under
parameters 705-708.
Terminal NO3 is a normally-open contact; it closes when the relay
activates. NC3 is a normally-closed contact; it opens when the relay
activates. RC3 is the common terminal associated with both contacts.
The ratings of these contacts are 115 VAC, 1 amp; and 230 VAC, 0.5 amp.
NO4
RC4
NC4
The fourth auxiliary relay.
The function of this relay is set by parameter 710. Functionally, it is
capable of each of the features outlined in the X5 user manual under
parameters 705-708.
Terminal NO4 is a normally-open contact; it closes when the relay
activates. NC4 is a normally-closed contact; it opens when the relay
activates. RC4 is the common terminal associated with both contacts.
The ratings of these contacts are 115 VAC, 1 amp; and 230 VAC, 0.5 amp.
A+
A-
Channel A input from the encoder. Compatible with line driver, open
collector, or totem pole outputs from an encoder. If it is an open collector
or totem pole-type, encoder outputs are used; connect the A- terminal to
Ecom.
B+
B-
Channel B input from the encoder. Compatible with line driver, open
collector, or totem pole outputs from an encoder. If it is an open collector
or totem pole-type, encoder outputs are used; connect the B- terminal to
Ecom.
C+
C-
Channel C input from the encoder, the home pulse. Compatible with line
driver, open collector, or totem pole outputs from an encoder. If it is an
open collector or totem pole-type, encoder outputs are used; connect the
C- terminal to Ecom.
VDC
Power supply terminal for use with a customer-supplied encoder. It can
be 12 VDC or +5 VDC based on the position of the encoder interface
power supply selector shown in Figure 1. Voltage regulation: +/- 5%;
maximum current available is 100 mA.
Ecom
Signal common for the encoder interface
