Function Specification

Supported: Functions that are used in target applications
-: Functions that are not used in target applications

Function		Application		Description
Function		Weight measurement *1	Force measurement *2	Description
I/O refreshing ethod setting *3		Supported.	Supported.	Sets Free-Run refreshing, synchronous I/O refreshing,4 or task period prioritized refreshing5 for the I/O refreshing*6 method.
Actual load calibration		Supported.	Supported.	This is a user calibration function that is performed by placing an actual load on the load cell.
Equivalent input calibration		Supported.	Supported.	This is a user calibration function that is performed by inputting the rated output, rated capacity, and zero balance values of the load cell.
Gravity acceleration correction		Supported.	-	This function corrects errors in the gross weight values that occur due to the difference of gravity acceleration at each site when the site where the actual load calibration of the device is executed and the installation site are different.
Digital filtering		Supported.	Supported.	This function uses the digital filter to remove noise components that are contained in input signals to suppress fluctuations of measurement values. You can use the digital low-pass filter and moving average filter.
Zero set/ zero reset		Supported.	Supported.	The zero set function corrects the gross weight value/force measurement value to be the zero point within the set range at a desired time. The zero reset function resets the zero point correction that is performed with the zero set function.
Zero tracking		Supported.	-	This function automatically corrects the zero point within the set range.
Zero point range over detection		Supported.	Supported.	This function detects when the gross weight value/force measurement value exceeds the set zero point range.
Tare subtraction		Supported.	-	This function subtracts the tare weight value from the gross weight value to acquire the net weight value. There are two types of this function: one-touch tare subtraction and digital tare subtraction.
	One-touch tare subtraction	Supported.	-	This function stores the gross weight value at the specified timing as the tare value and subtracts it from a given gross weight value to acquire the net weight value.
	Digital tare subtraction	Supported.	-	This function subtracts the preset digital tare value from the gross weight value to acquire the net weight value.
Stable detection		Supported.	-	This function detects whether the gross weight value is stable.
Over range/under range detection		Supported.	Supported.	This function detects when the input signal exceeds the input conversion range.
Sensor disconnection test		Supported.	Supported.	This function tests if the cable that connects the Load Cell Input Unit and load cell is disconnected. During the sensor disconnection test, you cannot measure the weight or force.
Input value refreshing stop		Supported.	Supported.	This function stops refreshing the input value in a specified period.
Peak hold/ bottom hold		-	Supported.	This function continues holding the peak value or the bottom value of the force measurement value in a specified period.
Data tracing		Supported.	Supported.	This function records the values in REAL data in the buffer of the Load Cell Input Unit and exports the data to a CSV file. These values indicate the gross weight values/force measurement values before and after the digital filtering in a specified period.
Decimal point position setting		Supported.	Supported.	This function sets the number of digits which is displayed after the decimal point for each DINT data.

*1. It is used to measure the weight in the unit of kg or t.
*2. It is used to measure the force in the unit of N or kN.
*3. Select with the Communications Coupler Unit setting. Refer to the NX-series Load Cell Input Unit User’s Manual
(W565) for details on the setting method.
*4. You can select this option only when the Unit is used with an EtherCAT Coupler Unit with EtherCAT communications
in DC Mode.
*5. You can select this option only when the Unit is used with an EtherCAT Coupler Unit NX-ECC203 with EtherCAT
communications in DC Mode.
*6. This is the data exchange with the Controller.
