Introduction
3.1
Features
The SM-Encoder Plus provides an interface for an additional encoder to be connected
to the Unidrive SP, to be used as position and speed feedback for the drive. Typical
uses for the SM-Encoder Plus would be to input a speed/position reference from a line
speed encoder, or to digitally lock the drive to a master reference using the position
controller in drive menu 13.
All three Solutions Module slots can be fitted with SM-Encoder Plus modules.

Solutions Module identification
The SM-Encoder Plus can be identified by:
1. The label located on the underside of the Solutions Module.
2. The colour coding across the front of the Solutions Module. All Unidrive SP
Solutions Modules are colour coded, with the SM-Encoder Plus being brown.

Date code format
The date code is split into two sections: a letter followed by a number.
The letter indicates the year, and the number indicates the week number (within the
year) in which the Solutions Module was built.
The letters go in alphabetical order, starting with A in 1990 (B in 1991, C in 1992 etc.).
Example:
A date code of L35 would correspond to week 35 of year 2002.
The SM-Encoder Plus does not have any simulated encoder outputs available.
