Features

The High-speed Analog Input Units are used to process analog input signals and trigger input signals.

The NX-series High-speed Analog Input Units have the following features.

Refer to 1-3 Model on page 1 - 9 for details on High-speed Analog Input Unit models and 1-4 List of

Functions on page 1 - 11 for details on their functions.

Sampling Period of 5 μs at the Shortest

The High-speed Analog Input Units can perform sampling in a sampling period of 5 µs at the shortest,

independent of the Controller’s task period.

You can change the sampling period by setting the number of samplings.

*1. The primary periodic task or the priority-5 periodic task should be assigned. If any other periodic task is as-

signed, the Unit does not perform sampling correctly.

Sampling Independent of the Number of Channels in Use

The High-speed Analog Input Units perform AD conversion in parallel for each channel that is in use.

This enables a sampling period of 5 µs at the shortest for each channel, independent of the number of

channels.

Easy Comparison of Analog Input Data between Channels

For channels that use the same number of samplings, the High-speed Analog Input Units can obtain

analog input values of each channel at the same timing. This enables easy comparison of analog input

data between the channels.

Improved Environmental Resistance by Individually Isolated Channels

The analog input channels of the High-speed Analog Input Units are individually isolated. This sup-

presses the fluctuations of analog input values due to interference between channels.

1 Features and System Configuration

Identification of Analog Input Values with Trigger Input

Both trigger input signals and analog input signals have time information. Based on their time informa-

tion, you can identify the analog input value that was read at the time of the trigger input. This enables

you to efficiently obtain the required analog input data.

1-1 Features

Can be Connected to a CPU Unit or Communications Coupler Unit

NX Units NX-series High-speed Analog Input Units can be connected to the following Units.

• NX-series CPU Unit

• NX-series Communications Coupler Unit*

When a CPU Unit and a Communications Coupler Unit are used together

for installing, wiring, and setting up NX Units, and eventually reduce design costs.

, you can unify the methods

*1. For whether NX Units can be connected to the CPU Unit to be used, refer to the user’s manual for the CPU

*2. The High-speed Analog Input Units can be connected only to an EtherCAT Coupler Unit.

Synchronous I/O with Refresh Cycle of the NX Bus

When the NX-series CPU Unit or EtherCAT Coupler Unit is used together with NX Units that support

synchronous I/O refreshing, the I/O control of multiple NX Units can be synchronized at the time to

synchronize with the refresh cycle of the NX bus.

This provides an accurate I/O control because it suppresses jitter in the I/O timing of multiple NX Units.

Simple I/O Wiring with a Screwless Clamping Terminal Block

The terminal block is a screwless clamping terminal block.

You can connect the wires simply by pushing the ferrules into the terminals. The amount of wiring work

is reduced without requiring the use of screws.

•

Moving average filter 1

• Moving average filter 2

Designing Digital Filters with Ease

You can use a library of the Sysmac Library to sample and record analog input values before and after

digital filtering.

By referring to the recorded results, you can identify the noise frequency band and confirm the noise

removal effect to design digital filters easily.

Example of Application System Configuration

The following figure shows an example of a characteristic inspection system configuration where an

NX-series High-speed Analog Input Unit is used.

The system reads analog input signals to detect abnormal noise, vibration and torque values through

the inspection, and determines whether the workpiece operation is acceptable or not.

It uses input from devices such as a photoelectric sensor as trigger input to efficiently obtain the ana-

log input data required for inspection.

In this way, you can configure a system based on a general-purpose Controller and perform character-

istics inspection without using special measuring equipment.

Precautions for Correct Use

• For the High-speed Analog Input Units, it takes time until the NX Unit I/O Data Active Status changes to TRUE when power is turned ON or the Unit is restarted. When you write the program, make sure that the Unit always checks if the NX Unit I/O Data Active Status has changed to TRUE before it starts operation. Refer to the software user's manual for the connected CPU Unit or the user’s manual for the connected EtherCA

T Coupler Unit for information on the NX Unit I/O Data Active Status.

• When you use an NX-series High-speed Analog Input Unit in the CPU Rack or Slave Terminal, the primary periodic task or the priority-5 periodic task should be assigned. If any other periodic task is assigned, the Unit does not perform sampling correctly. When any other periodic task is assigned, the High-speed Analog Input Units do not perform sampling throughout the task period. They perform sampling only during a part of the task period. Note that the Sysmac Studio does not display a correct sampling period on the Edit I/O Allocation Settings Window and the Sampling Settings and Digital Filter Settings Tab Page.

Calculating the Total Current Consumption from I/O Power Supply

The total current consumption of I/O power supplied from the NX bus must be within the range of the

maximum I/O power supply current of the Communications Coupler Unit or the Additional I/O Power

Supply Unit. However

CPU Unit, the maximum I/O power supply current value may be smaller than that of the Additional I/O

Power Supply Unit. For example, the maximum I/O power supply current for the CPU Rack of an

NX1P2 CPU Unit is 4 A. Refer to the hardware user’

connected for information on the restrictions for the CPU Rack.

To confirm this and to calculate the I/O power supply capacity, calculate the total current consumption

of the I/O power supply from the NX bus.

Note that the current consumption from I/O power supply indicated in the data sheet for each Unit type

does not include the load current of any external connection load and current consumption of any con-

nected external devices.

The total current consumption from I/O power supply of the High-speed Analog Input Units is calculat-

ed as follows:

Preventing Incorrect Attachment of Terminal Blocks

In order to prevent unintentionally installing the wrong terminal block, you can limit the combination of

a Unit and a terminal block.

Insert three Coding Pins (NX-AUX02) into three of the six incorrect attachment prevention holes on the

Unit and on the terminal block. Insert these pins into positions so that they do not interfere with each

other when the Unit and terminal block are connected to each other

You can use these pins to create a combination in which the wrong terminal block cannot be attached

because the pin patterns do not match.
