4.5.4 MCO Encoder Connection
MCO 351 provides 2 encoder interfaces, X55 and X56.
Terminal block X55 is configured as the default feedback
encoder input.
Encoder supported
•
TTL/RS422 incremental encoder (X55, X56)
•
SSI absolute encoder - Grey code (X55, X56)
•
Sin/Cos Encoder 1 Vpp (only X55)
•
Resolver (needs extra option MCB103) - only in
speed closed loop.
•
CANopen encoder (X62)
NOTICE
Use parameter
32-50 Source Slave
for setting encoder
feedback to
[1] Encoder 1 X56
or
[3] Motor Control
.
4.5.4.1 Encoder Connection Examples
Example 1
Encoder connected to X55 for positioning loop. Since the
encoder is mounted directly on the motor shaft, the same
feedback can be used for the MCO positioning loop and
the FC speed control loop.

Example 2
Encoder connected to X55 for positioning loop. Since the
encoder is
not
mounted directly on the motor shaft, this
configuration can be used for the MCO positioning loop
and the FC speed control loop.
