Siemens SIMOTICS 1FL6 Series Motors

Overview

These are permanent-magnet synchronous motors that will normally come equipped with an incremental encoder, 2500ppr (10,000 count) or two possible options with BiSS encoders a 21 bit single turn type or with a 20 bit single turn absolute encoder and 12 bit multi-turn function. 

General Information

Image 1. "Nameplate Configuration".

Note: The "M" identifier isn't listed in the English version manuals from Siemens you can only find a reference of the encoder by looking at the Spanish version.

Image 2. "Nameplate Configuration (Spanish)".

The "L and M" encoders appear to be using the BiSS protocol and the "A" type encoder can be tested with the software selection as "Generic Incremental". 

• Note: For the "Absolute Encoder" notice how it's a 20 bit + 12 bit, our software would normally list it as "1220" however we don't have that option yet so the "1219 BiSS Serial Encoder" selection would work best the same applies for the 21 bit single turn encoder. 

Connection

Siemens 1FL6 motors are available with several different types of connectors, each suited for specific application needs. 

Connector Type '0' refers to the old-style angled plug, which supports either a generic ABZ encoder or a BiSS interface for motors with straight connectors.

Connector Type '1' features a 15-pin D-sub (DB) connector for the BiSS interface (TI-5780) and a 12 pin Molex connector for incremental encoders (TTL 2500 ppr) (TI-5782). 

Connector Type  '2' is the newer design, straight plug, exclusively for ABZ encoders.
