It is necessary to readjust the offset value and the gain value when FX 2N -2AD is used by current input, the 0 to 5V DC voltage input, or with an input characteristic the factory setting. The adjustment of the offset value and the gain value sets a digital value to the analogue value actually input by using the voltage generator and the current generator according to the volume of FX 2N -2AD.*1 A digital value increases if the volume installed in FX 2N -2AD is turned right (clockwise).(FX 2N -4DA and FX 2N -2DA can be used instead of the voltage generator and the current generator)+-V+-VIN {IIN {C O M {FX 2N -2AD Voltage generator+A +-VIN {IIN {C O M {FX 2N -2ADCurrent generatorA/DOFFSET volume AD GAIN volumeVoltage input Current input Volume*17.1.1 Adjustment of gainThe gain value can be set to an arbitrary digital value.However, to demonstrate the resolution of 12bit to its maximum, a digital range of 0 to 4000 is available.A digital value is adjusted to 4000 at 10V in the analog input value when the voltage is input.

However, it is advisable to set the analog value when the digital value is set at the following.For instance, when a digital range of 0 to 4000 is used with the analog range of 0 to 10V, a digital value of 40 is equal to an analog input of 100mV.

When the offset value/the gain value of one channel is adjusted, the other value is automaticallyadjusted. 2)Repeat the offset adjustment and gain adjustment alternately until a stable value is reached. 3)Each channel is common to the analog input circuit. There are the few differences between channels.However, check each channel individually for maximum accuracy.4)Adjust offset / gain by using subsection 8-2 "Example of programming making average value data"when a digital value is not steady. 5)Do in order of the gain adjustment and the offset adjustment when you adjust offset/gain.8.Program exampleThe following program examples (8.1 and 8.2) are formula circuits.The device numbers that have been underlined can be assigned by the user during programming.8.1Example of programming analog inputReading of digital value of CH2.X000[T0 K0 K17 H0000 K1 ][T0 K0 K17 H0002 K1 ][FRO M K0 K0 K2M100 K2 ][M O V K4M100 D100 ]33X001[T0 K0 K17 H0001 K1 ][T0 K0 K17 H0003 K1 ][FRO M K0 K0 K2M100 K2 ][M O V K4M100 D101 ]Selecting A/D input channel 1.A/D conversion beginning of CH1.Reading of digital value of CH1.The high rank 4 bits of CH1 arem oved to the subordinate position8 bits, and it is stored in D100.Selecting A/D input channel 2.The high rank 4 bits of CH2 arem oved to the subordinate position8 bits, and it is stored in D101.A/D conversion beginning of CH2.*1*1a)b)c)d)e)f)g)h)Analog to digital conversion execution input of CH1:X000Analog to digital conversion execution input of CH2:X001A/D input data CH1 :D100 (Replace with auxiliary relay M100 to M115.

It is necessary to readjust the offset value and the gain value when FX 2N -2AD is used by current input, the 0 to 5V DC voltage input, or with an input characteristic the factory setting. The adjustment of the offset value and the gain value sets a digital value to the analogue value actually input by using the voltage generator and the current generator according to the volume of FX 2N -2AD.*1 A digital value increases if the volume installed in FX 2N -2AD is turned right (clockwise).(FX 2N -4DA and FX 2N -2DA can be used instead of the voltage generator and the current generator)+-V+-VIN {IIN {C O M {FX 2N -2AD Voltage generator+A +-VIN {IIN {C O M {FX 2N -2ADCurrent generatorA/DOFFSET volume AD GAIN volumeVoltage input Current input Volume*17.1.1 Adjustment of gainThe gain value can be set to an arbitrary digital value.However, to demonstrate the resolution of 12bit to its maximum, a digital range of 0 to 4000 is available.A digital value is adjusted to 4000 at 10V in the analog input value when the voltage is input. A digital value is adjusted to 4000 at 20mA in the analog input value when the current is input.D i g i t a l v a l u eA nalog value10V 4000V oltage inputcharacteristic(0 to 10V )W hen factory is shipped D i g i t a l v a l u eA nalog value5V 4000V oltage inputcharacteristic(0 to 5V )D i g i t a l v a l u eA nalog value020m A4000C urrent inputcharacteristic(4 to 20m A )4m A 7.1.2Adjustment of offsetThe offset value can be set to an arbitrary digital value. However, it is advisable to set the analog value when the digital value is set at the following.For instance, when a digital range of 0 to 4000 is used with the analog range of 0 to 10V, a digital value of 40 is equal to an analog input of 100mV.

When the offset value/the gain value of one channel is adjusted, the other value is automatically adjusted. 2)Repeat the offset adjustment and gain adjustment alternately until a stable value is reached. 3)Each channel is common to the analog input circuit. There are the few differences between channels.However, check each channel individually for maximum accuracy.4)Adjust offset / gain by using subsection 8-2 "Example of programming making average value data"when a digital value is not steady. 5)Do in order of the gain adjustment and the offset adjustment when you adjust offset/gain.8.Program exampleThe following program examples (8.1 and 8.2) are formula circuits.The device numbers that have been underlined can be assigned by the user during programming.8.1Example of programming analog inputReading of digital value of CH2.0X000[T0 K0 K17 H0000 K1 ][T0 K0 K17 H0002 K1 ][FRO M K0 K0 K2M 100 K2 ][M O V K4M 100 D100 ]33X001[T0 K0 K17 H0001 K1 ][T0 K0 K17 H0003 K1 ][FRO M K0 K0 K2M 100 K2 ][M O V K4M 100 D101 ]Selecting A/D input channel 1.A/D conversion beginning of CH 1.Reading of digital value of CH1.The high rank 4 bits of CH 1 arem oved to the subordinate position 8 bits, and it is stored in D 100.Selecting A/D input channel 2.The high rank 4 bits of CH 2 are m oved to the subordinate position 8 bits, and it is stored in D 101.A/D conversion beginning of CH 2.*1*1a)b)c)d)e)f)g)h)Analog to digital conversion execution input of CH1:X000Analog to digital conversion execution input of CH2:X001A/D input data CH1 :D100 (Replace with auxiliary relay M100 to M115.

FX2N-2DA模块和FR-E540在调速中的应用作者：都晔凯来源：《职业·下旬》2012年第01期在设备的控制过程中，经常会遇到电动机调速控制。

变频调速以其调速范围广、转速稳定性好、机械特性较硬、静差率小、性价比高等优点被广泛采用。

一、变频器的频率设定方法1.变频器的频率设定变频器的操作方式不同，运行指令和频率设定信号的来源也不同。

通常可以用PU操作面板、电位器、外部多段速端子、模拟电压信号（0～10V或0～5V）、模拟电流信号（4～20mA）等方式进行变频器频率的设定。

其中，由于模拟电压、电流信号设定频率的方式控制精度高、调速连续性和随动性好、易实现自动化，因此在控制要求相对较高的场合大多数采用这种方式设定变频器的频率。

2.PLC模拟量控制方式在变频调速中的应用在复杂的自动化控制系统中，PLC经常被作为控制核心，用于采集输入信号、执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。

PLC包括许多的特殊功能模块，而模拟量模块则是其中的一种。

它包括数模转换模块和模数转换模块。

数模转换模块可将一定的数字量转换成对应的模拟量(电压或电流)输出，这种转换具有较高的精度。

下面介绍三菱FX2N-2DA模拟量输出模块控制E540变频器频率的方法。

二、硬件连接1.变频器主回路图1所示为变频器的控制及动力部分。

变频器采用外部控制模式，运行指令来自于外部控制端子，频率信号来自于PLC模拟量输出模块FX2N-2DA，由变频器的端子2、5输入，其中2为模拟电压信号端子、5为公共端，采用出厂设置，为0～5V信号输入。

2.PLC接线控制系统采用具有两路模拟量输出的FX2N-2DA模块对两个变频器进行速度控制。

将FX2N-2DA模块的IOUT与COM短路，选择0～5V输出信号。

分别将模块的VOUT、COM 与变频器的2、5端子相连。

模块的增益可设定为任意值。
