Overview; Features - NSD Absocoder NCV-40H Series Specifications & Instruction Manual

1. OVERVIEW

NCV-40H Series is a converter that is highly improved the durability and reliability for iron and steel industry.
The converter uses with the multi-turn and high resolution type ABSOCODER sensor.
It converts the detected position data (absolute value) to binary or gray code, and then the code is output.
Either sink type or source type is selectable for the I/O circuit.

1-1. Features

(1) For the multi-turn and high resolution type ABSOCODER sensor
The position detection can be done by the multi-turn and high-resolution type ABSOCODER sensor.
MRE-1024S16TS1002: 65536 division per turn (maximum: 1024 turns)
MRE-8192S2TS100: 8192 division per turn (maximum: 8192 turns)
(2) 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.
(3) Superior durability
NSD's original ABSOCODER is used as the position sensor which features a no-contact construction for
excellent durability. This sensor offers problem-free operation, even in environments where it is exposed to
vibration, impact shocks, extreme temperatures, oil, and dust.
(4) 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.
(5) Zero point setting function
The position data can be set to "0" by using either pressing the "ZPS" switch on the front panel or inputting the
"ZPS" external input signal.
(6) A full array of position data reading formats
a) Latch pulse format
Position data reading occurs by synchronizing with the latch pulse signal output from the converter.
A position data update cycle (0.1ms, 0.2ms, 0.4ms, 0.8ms, 1.6ms, 3.2ms, 6.4ms, 12.8ms, 25.6ms, 51.2ms)
which is suitable for the host controller's reading speed can be selected.
b) HOLD signal format
A HOLD signal is input to the converter to stop position data output updates, with the position data then
being read.
This desired HOLD signal format can be selected from two types:
- The transparent format in which data reading occurs while the HOLD signal is ON.
- The PC synchro format in which position data updates occurs at the HOLD signal's leading or trailing
edge.
(7) Error detection function
The error content can be checked by a converter monitor "LED" when an error occurs.
A status output is also provided, enabling reading to a host controller (PLC, etc.).
