Extra incremental encoder
Some applications require the connection of multiple encoders typically when:
• A single axis has multiple encoders on the same motion system to eliminate
mechanical errors (a dual encoder application).
• The drive is required to follow encoder signals given to it from a master encoder
input.
In both cases the drive can support a connection to an extra incremental encoder by
X7 (see page
83 ) or X8. The default extra incremental encoder input (encoder 2) is
X7.If X7 is occupied as an encoder output and the primary feedback type is one that
does not use the Hall/sin/cos inputs (Incremental encoder without Halls, BiSS-B, SSI,
EnDat 2.2, Smart Abs or resolver), the extra incremental encoder also can be
connected to X8.
Note : In Mint, this extra encoder input (encoder 2 on X8) is available only when
connector X7 has been configured as an encoder output (see page 84 ) .
When connector X8 is specified as encode 2, a encoder breakout OPT-MF-200 need
to be mounted to split one 15-pin connector X8 into one 15-pin connectors X8A and
one 9-pin X8B. X8A is connected to motor feedback, while X8B is connected to an
extra incremental encoder (see page
180 ).
