Feedback Option Cards
There are three different feedback option cards that can be installed on the
PowerFlex 700S:
• The Hi-Resolution Encoder Feedback Option Card
• The Resolver Feedback Option Card
• The Multi Device Interface (MDI) Option Card
Only one of the option cards above can be physically installed on the drive at a
time. When the Hi-Resolution encoder option or Resolver option are installed,
their data is processed by feedback option card port 0. When the MDI option is
installed, it has a Hi-Resolution encoder processed by feedback option card port
0 and a Temposonics linear sensor processed by feedback option card port 1.
Parameter 251 [FB Opt0 Spd Fdbk] contains the speed feedback from either the
Hi-Resolution Encoder or the Resolver connected at port 0.
Parameter 250 [FB Opt0 Posit] contains the position feedback from either the
Hi-Resolution Encoder or the Resolver connected at port 0.
Parameter 277 [FB Opt1 Spd Fdbk] contains the speed feedback from the
Temposonics linear sensor when the MDI option is installed.
Parameter 276 [FB Opt1 Posit] contains the position feedback from the
Temposonics linear sensor when the MDI option is installed.
Parameter 249 [Fdbk Option ID] displays information about the feedback
option installed in feedback option card port 0. This information is read from the
feedback option card. Bits 15…11 will be a value of 2000 hex for an old hi-
resolution option card and a value of 2020 hex for a new hi-resolution option
card.
