 SM-UNIVERSAL ENCODER PLUS
The SM-Universal Encoder Plus module provides the Unidrive SP with an additional
feedback port that supports all of the same feedback types as the base drive,
plus has a simulated encoder output that can be programmed to operate in
the following modes:
- Quadrature Incremental
- Pulse and Direction
- SSI
The module also incorporates freeze inputs for applications requiring position
capture.  SM-ENCODER PLUS
The SM-Encoder Plus module provides an additional quadrature incremental
encoder
feedback port.
Note: More than one SM-Encoder Plus and/or SM-Universal Encoder Plus module
may be installed in a single drive.
 SM-RESOLVER
This module enables the Unidrive SP to control the speed and position
of motors fitted with resolvers. Because of their ruggedness, resolvers
are often used in hot, demanding enviornments.
