1397 Pulse Encoder Interface Card
The Pulse Encoder Interface card is a drive mounted board that provides
terminals and an interface to differential encoder feedback signals for both
regenerative and non-regenerative 1397 drives.
For additional information on encoder signal requirements, wire
recommendations, encoder parameters and related function blocks, see the
Bulletin 1397 DC Drive Firmware 2.xx User Manual, publication 1397-UM000
,
and Pulse Encoder Interface Installation Instructions, publication 1397-IN002
,
for more details.
Terminal Blocks J5 and J6 are available for either regenerative or non-regenerative
drive connection. Note: Only regenerative drives allow motor reversing.
Regenerative drives require that quadrature pulse encoders be used.
