Overview
The NR60E2 is a line of heavy-duty resolver based
encoder products from AMCI. The NR60E2 net-
worked resolver encoders communicate over a wired
Ethernet network using the EtherNet/IP, PROFINET,
or Modbus TCP communications protocol.
The NR60E2 resolver based encoder is a direct
upgrade for optical encoders. Instead of a glass disk
and associated optics, the primary position sensor in
an NR60E2 is an absolute resolver. Resolvers are
absolute, single turn position sensors that are con-
structed in a manner similar to rotary transformers.
They are manufactured from passive components,
with enameled copper wire and metal laminations the
primary components. Additional information on the
workings of a resolver can be found on the AMCI
website at:

The NR60E2 series is composed of absolute single- or multi-turn sensors in an IP67 rated, 60 mm diameter
package. All NR60E2 Networked Resolvers offer a maximum single turn position resolution of 16 bits, which
is programmable from 1 to 65,536 counts per turn. Two multi-turn units are available in addition to the single
turn NR60E2. One encodes 4,096 turns (12 bit + 16 bit = 28 bit encoder) and the other encodes 16,384 turns
(14 bit + 16 bit = 30 bit encoder). Multi-turn sensing is through an absolute magnetic encoder.
A flange mount unit with end connectors is shown in figure R1.1. The following mounting styles are avail-
able:

2.5 inch standard flange mount with 0.375", 0.250", or 10 mm shafts

58 mm standard servo mount with 6 or 10 mm shafts

63 mm standard blind shaft mount with 0.375", 0.250", 10 mm, or 12 mm diameter hubs
The body material is either aluminum with a powder coat finish, or stainless steel. Side and end connect ver-
sions of these mounting styles are available with aluminum bodies. Stainless steel bodies are only available in
end connect versions. Outline drawings of all of the packing options are available in the
Outline Drawings
section of the manual starting on page 24.
Each NR60E2 encoder has two external network connections using industry standard M12 D-coded connec-
tors. These two ports are internally connected through an onboard, two port, 10/100 Mbps ethernet switch.
Every NR60E2 resolver based encoder is programmable over its Ethernet interface. Parameters allow you to
set the count direction, the number of counts per turn, the number of counts before returning to zero, the for-
mat of the velocity data, and preset the position data to any value within its range.
When configured as an EtherNet/IP device, the NR60E2 implements the Encoder Device Profile as defined
by the CIP Specification revision 2. Custom Assembly instances simplify working with the NR60E2, but the
encoder also supports the CIP Position Sensor Object. Its dual Ethernet ports allows the NR60E2 to partici-
pate in DLR networks as a Beacon-Based Ring Node that can process beacon packets every 400 microsec-
onds.
When configured as a Modbus TCP device, the NR60Es supports a variety of Modbus Functions to simplify
reading and writing the device.
When configured as a PROFINET device, the NR60E2 encoder fully supports the Class 3 V4.1 specification.
In addition, NR60E2 encoders support the Class 4 MUR, TMR, Code Sequence, and Preset parameters as
well as their additional control parameters. Its dual Ethernet ports allows the NR60E2 encoder to be used as
clients in PROFINET networks that support the Media Redundancy Protocol (MRP).
