DC Drive Resolver Feedback Option Module
Switch S2 on the resolver interface board must be set to the “Ext” position when
using an external 24V DC power supply for the resolver feedback option module.
Table 2 - Resolver Interface Board TB1 Terminal Descriptions
Figure 2 - Resolver Feedback Board Voltage Status Wiring Example
Terminal block TB2 on the resolver interface board is used to send the signals
from the primary digital encoder installed and wired to the encoder terminal
block on the control board to a second “follower” drive/regulator. When the
outputs on TB2 are used, switch S1 on the resolver interface board must be set to
match the encoder power supply voltage set for the primary encoder on the
follower drive’s control board (set via switch S21). See the PowerFlex Digital DC
Drive User Manual, publication
20P-UM001 , for details on installing a primary
digital encoder and using switch S21 on the control board.
The S1 switch settings correspond to each of the three LEDs on the left side of
the resolver interface board and indicate the selected supply voltage as follows:
• Green LED indicates a 5V supply when lit (on)
• Yellow LED indicates a 12V supply when lit (on)
• Blue LED indicates a 24V supply when lit (on)
See Figure 3 on page 13 for the location of switch S1 and corresponding LEDs on
the resolver interface board.
See “Cable and Wiring Recommendations” in the PowerFlex Digital DC Drive
User Manual, publication
20P-UM001 , for encoder wiring recommendations.

0V External power supply input common
2 +24V External +24V DC power supply input
3 OK- Resolver feedback board voltage status output common
4 OK+ +5…24V Resolver feedback board voltage status output
Vcc OK = voltage present and within +5…24V range
when connected to a digital input.
Vcc not OK = voltage not present or below +5V when
connected to a digital input. See
Figure 2 below for
wiring example.
5 R- Resolver feedback board reset input common
6 R+ +24V Resolver feedback board reset input

In this example digital input 2, on drive I/O TB2, is configured as an Enable input. When the signal
from terminals 3 and 4 on TB1 of the Resolver Interface board = “VCC not OK,” the drive is disabled.
