NSD ABSOCODER NCW-3DNECMP Specifications & Instruction Manual page 8

1. OVERVIEW
NCW-3DNECMP (hereinafter referred to as NCW-3DNEC) is an ABSOCODER converter, a slave unit for EtherCAT,
can communicate with EtherCAT. With the use of NCW-3DNEC in combination with the multi-turn type of
ABSOCODER sensor, the machine position can be detected. The detected position data can be transmitted to the
industrial computer through the EtherCAT communication.
Or, the industrial computer can readout the converter status information and set parameters.
This manual explains by using a configuration tool "TwinCAT2 System Manager" developed by BeckhoffAutomation
GmbH. For the details of the tool, refer to the TwinCAT2 System Manager manual.

1-1. Features
(1) High reliability
An absolute position detection format ensures accurate position detection even if a power interruption or
unexpected noise condition occurs. An origin returning operation is not required.
(2) Superior durability
ABSOCODER sensor is not used electronic parts except coils and resistance, and it features a no-contact
construction excepting bearing. This sensor offers problem-free operation, even in environment where it is
exposed to vibration, impact shocks, extreme temperatures, oil, and dust.
(3) Compact design
The unit's outside dimensions (39(W) x 155(H) x 93(D)) were miniaturized. DIN rail can be used, so mounting is
much easier.
(4) EtherNet/IP communication
A position, preset, alarm, and parameter data can be transmitted through the EtherCAT network.
- The converter supports full duplex (100BASE-TX), so data can be transmitted faster.
- Communication is possible by the cycle within 125μs.
(5) Two ABSOCODER sensors can connect
The machine positions for two axes can be detected by one converter. The space-saving in the control panel can
be conducted.
(6) Diagnosis function
The error information can be expressed both by EtherCAT alarm data and by monitor LEDs on the converter's
front panel.
(7) Preset function
The position data can be preset to the desired value from the EtherCAT master.
(8) Configuration tool (software for configuring the system)
Settings are available by using EtherCAT software.
