Group 1 Expansion Board
The Resolver to Digital Interface expansion board provides
closed loop operation for the Baldor Series 18H, 19H, 20H and
22H controls. The Resolver to Digital Interface can also be used
for PID control.

Note: When a Resolver to Digital Interface is used in a process
control application, an encoder should be used to provide
velocity feedback to the control.
velocity feedback to the control.
Specifications
The Resolver to Digital interface is used with a motor mounted
resolver. This provides the correct feedback signals for the
Baldor Control. The control can then monitor and control shaft
position. The Buffered Encoder Output (Retransmit) signals are
still available from the control.
