Wiring the Resolver Interface Board
Table 1 - Resolver Interface Board TB1 Wire Size and Tightening Torque
Terminal block TB1 on the resolver interface (bottom) board provides
connection points for an external 24V DC power supply input, resolver feedback
board voltage status output and resolver feedback board reset input.
details the connections.
The resolver feedback module can be powered via an internal or external
(customer-supplied) 24V supply. The voltage source is selected by switch S2 on
the resolver interface board. See
for the location of switch S2.
The customer-supplied, external 24V power supply is only needed when using
the resolver interface board with a PowerFlex DC frame A drive or Stand-Alone
Regulator under the following conditions.
• A resolver is wired to the resolver feedback board (terminal block P1)
• A digital encoder is wired to the control board
• The frame A drive has a fan(s)
