Component Test Procedures
Chapter 2
Check the DC Tachometer
• Verify that DIP switch S4 on the control board is set to the correct input
voltage of the DC analog tachometer. See “DIP Switch and Jumper
Settings” in the PowerFlex Digital DC Drive User Manual, publication
. Also, see
on page
for a circuit diagram.
• The analog tach signal is fine scaled using parameter 562 [Anlg Tach
Gain].
• See “Drive Reference and Feedback Scaling” in Appendix C of the
PowerFlex Digital DC Drive User Manual, publication
for more information.
Check the Resolver Interface Board
The resolver feedback option module uses the resolver feedback board for
resolver connections, and the resolver interface board for external power,
status, feedback board reset, and encoder output connections.
If a “Resolver Error” (F93) fault occurs and the resolver wiring and
configuration are correct, the following light-emitting diode indicators and
testpoints on the resolver interface board can be used to verify that the board is
not damaged.
• Verify that the following light-emitting diodes are functioning as
expected. See
Figure 12
on page
36
for light-emitting diodes locations
and switch settings.
If any of the light-emitting diodes that should turn on when control power is
applied fail to do so, verify that the resolver interface and resolver feedback
boards are properly seated on the appropriate connectors (XRE, P2, P3). If
problems persist, replace the resolver interface and/or resolver feedback board
(see page
