NX2A4E2 Programmable Parameters
Common Parameters
These parameters are available on the NX2A4E2 regardless of the type of transducer used.
Resolver Type
This global parameter configures the NX2A4E2 for AMCI transducers, or transducers from AVG/Autotech or
Gemco. This parameter alters the reference voltage to the resolvers so that the return signals are compatible
with the NX2A4E2 resolver inputs. Therefore, you cannot mix resolver types when using this parameter. If
you need to interface both resolver types to the NX2A4E2, you will have to purchase a separate item from
AMCI with the part number RM-3. The RM-3 Reference Module is a single ended transformer that wires into
the transducer cable and alters the reference voltage for the foreign transducers.
AMCI also offers the RM-1 Reference Module to interface Namco/C&A transducers with the
NX2A4E2, and the RM-5 to interface Reliance or Tamagawa resolvers.
Enable Channel Status LED
These four parameters allow you to selectively disable the status LED’s on channels you are not using in your
application.
Transducer Fault Latch
This parameter is available on each transducer input channel and gives you programmable control over
whether or not transducer faults are self clearing or latched. Self clearing faults clear themselves as soon as
the resolver signals return to valid values. Latched faults must be cleared by the host. The factory default set-
ting is for self clearing faults.
Count Direction
This parameter is available on each transducer input channel and gives you programmable control over the
direction of rotation needed to produce increasing counts. When you use AMCI transducers that are wired as
shown in this manual, the factory default setting is for clockwise increasing counts when looking at the trans-
ducer shaft.
Tachometer Response
This parameter is available on each transducer input channel and gives you programmable control over the
update time of the tachometer value. The Tachometer Response can be programmed to 120 milliseconds or 24
milliseconds, and is 120 milliseconds by default. Note that this parameter only affects the update time of the
tachometer value. It does on affect the position update time, which is always 200 microseconds.
Single Turn Parameters
These parameter are available when the module is used with single resolver or redundant resolver transduc-
ers.
Full Scale Count
This parameter allows you to set the number of counts reported by the NX2A4E2 for a full rotation of the
resolver. This parameter has a range of 2 to 8,192, with a factory default of 1,024.
