Gemco Cables Like their transducers AMCI handles Gemco cabling questions on a case by case basis Contact AMCI if you have any questions about using Gemco cabling in your application Using AMCI Transducers With Controllers From Other Manufacturers If you can get a transducer from another manufacturer working with an AMCI controller then it is also possible to get an AMCI transducer to work with the controllers from that manufacturer that interface with its transducer This is accomplished by installing the RM module as shown on page 2 of this FAQ but reverse its Input and Output connections The Output connection Pin 1 of the RM goes to the controller and the Input connection Pin 2 goes to the AMCI transducer Remember that dual resolver transducers from AMCI will generally not work with competitors controllers because of a difference in gearing styles Using AMCI and a Competitors Transducer Together If your AMCI controller has multiple transducer inputs you bring AMCI transducers and transducers from other manufacturers into the controller by wiring the AMCI transducer directly into the controllers Trans ducer Input Connector and attaching the other transducers through a Reference Module The following figure is an example of doing this with Autotech transducers Module Connector Mates with Transducer Input Connector MS 8 shown To AMCI MS 16 Connector Pin A To AMCI MS 16 Connector Pin B VODSSVDO nlo aA a alin o

5. FAQ 940 1F091 AMICI Frequently Asked Question Can I Use Transducers From Other Manufacturers With AMCI Controllers When AMCI receives an inquiry about using foreign products it is generally about transducers from one of four companies Autotech Namco C amp A ElectroCam or Gemco Some of the transducers made by these companies can be used with AMCI controllers and some cannot It depends on the type of transducer and how the resolver itself is wired in the transducer Even though it is possible to use transducers from other manufacturers we strongly suggest using AMCI transducers whenever possible AMCI is the only company in the marketplace that designs and manufactures the resolvers used in its products Our transducers and modules are designed to work together and will work for years to come when specified and installed properly gt Because you can use some transducer from other manufacturers with AMCI controllers the reverse of the question is also true You can use AMCI transducers with controllers from other manufactur ers The last section of this FAQ covers how to accomplish this Types of Transducers AMCTI and the three of the four companies listed above make two types of resolver based transducers sin gle resolver transducers and dual resolver transducers Single resolver transducers come in two forms The first is the single turn transducer The resolver is directly coupled to the transducer s input shaft and

9. one turn of the input shaft yields one turn of the resolver The second form of the single resolver transducer is the geared multi turn In this package the resolver is attached to the input shaft through a gear reduction so that multiple turns of the input shaft yield one turn of the resolver To the controller single resolver transducer appear to make only one rotation per cycle The controller is unaware of any gear ratio between the transducer s input shaft and the resolver It is usually possible to make single resolver transducers for other manufacturers compatible with AMCI controllers In most cases you will need to purchase a Reference Module from AMCI in order to make the transducer work with AMCI products As the name implies dual resolver transducers contain two resolvers and are designed for high resolution multi turn applications The first resolver is directly coupled to the input shaft while the second resolver is attached to the first through a gear ratio This ratio defines the number of turns the transducer can encode Due to differences in gearing it is usually not possible to make dual resolver transducers for other manu facturers compatible with AMCI controllers If you want to use a dual resolver multi turn transducer or your transducer is not from Autotech Namco C amp A ElectroCam or Gemco you must contact AMCI for assistance Reference Modules Resolvers are similar to rotary transformers and one of a resolv
