been met with a 19mm wrench and
remove the gap tool.
Encoder Electrical Connection
NOTE:
Before connecting any encoder onto
the drive, make sure that the encoder can
operate at 12V
DC
because the power supply on
the drive will be 12V
DC
.
NOTE: The TerMag board part number
46S04284-0010 will not work on the Axial Flux
drive. The TerMag board used on the Axial
Flux is pn 46S04284-1020
The encoder cable has 3 twisted wire pairs.
The connection of the encoder to the drive is
shown in
Figure 11 .

Proximity Sensor Electrical
Connection
NOTE:
The proximity sensor should ONLY be
used on TerMag board number 46S04284-
1020.
The proximity sensor cable should be wired up
to the drive as shown in
Figure 12 . When
connecting the cable to the proximity sensor,
latch the coupling ring on the female (cable
end) connector into its open position (rotate
the ring clockwise as you look into the sockets
of the connector). Then insert the male
(proximity sensor end) connector into the
female (cable end) connector. Finally, rotate
the coupling ring on the female connector in
the opposite direction until it latches into its
closed position.

SW1: It is recommended that the 2 dip
switches for encoder channel filtering be
turned on (up position) for SW1 as shown in
Figure 13 : SW1-2 is the filter for Z and SW1-3
is for A/B. SW1-1 is used to place a 120 ohm
terminating resistor across the receiver input
for serial communication; it should be in the on
position when serial cables longer than 50 feet
is being used.
SW2: The proximity sensor requires a 12V
DC
power supply. So if not already done, SW2 on
the TerMag Board should be set for the 12V
(right position) rather than the 5V power supply
(left position) as shown in
Figure 13
.
SW3: SW3 should also be configured so that
the A and B channels are set for differential
input and the Z channel is set for single ended
input as shown in
Figure 13 ; starting from the
left: up, down, down, up, down, and up.
