Available ranges are: ±10V, ±5v, 1-5v, ±20m, 4-20mA. Example: When the defined mode is ±10V, the default scale range is ±32000. Converting analog value 10v will get the upper limit of the range, which is 32000. Converting analog value -10v will get the lower limit of the range, which is -32000. Upper Limit 10v 5v 5v 20mA 20mA Lower Limit -10v Mode: ±10v -5v 1v -20mA 4mA ±5v 1-5v ±20mA 4-20mA 10 iR-AQ04-VI iR-AM06-VI iR-AI04-VI User Manual Mode: ±10v Mode: ±5v Upper Limit Upper Limit Lower Limit Lower Limit -10v 10v -5v 5v Mode: 1-5v Mode: ±20mA Upper Limit Upper Limit Lower Limit 1v Mode: 4-20mA Upper Limit Lower Limit 5v -20mA 20mA Lower LimIt 4mA 20mA The upper and lower limit of the scale range can be configured for each mode. When switching from one mode to another, the upper and lower limit will return to default; therefore, when using this feature, please set the mode before configuring the range. By default the upper and lower limit of the range for each mode is as below: Mode -10~10V -5V~5V 1~5V -20~20mA 4~20mA Minimum -32000 -32000 0 -32000 0 Maximum 32000 32000 32000 32000 32000 11 iR-AQ04-VI iR-AM06-VI iR-AI04-VI User Manual Analog Output Soft Start Generally, when changing analog output value, the voltage or current output will change immediately. To gradually increase or decrease output for reducing potential system impact, an [Output Update Time] parameter can be configured. Adjusting Output Update Time can get a slew rate where the change of voltage or current from minimum to maximum value per unit of time is defined, as illustrated in the following figures. Analog Value Upper Limit Lower Limit Analog Value Output Update Time m( Slope) Time m m m Time Parameter Output Update Time Description The time unit is 10ms. By default this parameter is set to 0 (disabled). The maximum allowable setting is 3200 (32 seconds) Default 0 12 iR-AQ04-VI iR-AM06-VI iR-AI04-VI User Manual Analog Input Diagnose A channel alarm will be generated when input exceeds allowable range. In 1-5V / 4-20mA mode, disconnection can be detected when voltage is 0v or current is 0mA. Analog Input Fast Conversion Mode The conversion time per channel is 2ms. The total required conversion time is calculated by multiplying 2ms by the number of channels, for example, 4 channels will take 8ms for conversion. In fast conversion mode, where only one channel is used, the conversion time can be reduced to 500us. Fast Conversion Mode can be enabled by setting the corresponding register to 0.5ms. Under this mode, only one channel can be used. If channel 0 is not closed, the rest of the channels will not be able to perform conversion. If channel 0 is closed where channel 1 is opened, only channel 1 can perform conversion while the rest cannot. Analog Input Digital Filter The built-in filter enhances signal precision to achieve better control. Setting a slower conversion rate will get a better signal quality. By default the conversion time is 2ms. Setting 60ms can effectively filter out noises in a 50/60Hz environment. The Filter Frame Size can stabilize the signal by averaging sampled values, in order to achieve better control. 7.

Analog Channel Calibration for Value Correction Analog input channels may experience decreased measurement accuracy caused by factors such as variations in connected loads, system aging, and component wear over time. The following example demonstrates a self-adjustment method. Voltage Mode Calibration Analog Input Module 1-5V Voltage Source Step 1. Channel parameter configuration: Set Input Mode to 1-5V mode. Set Input Scale Range Upper Limit to 32000. Set Input Scale Range Lower Limit to 0. Step 2. Record the lowest voltage value: Set the standard voltage source to output 1V and record the channel value. Step 3. Record the highest voltage value: Set the standard voltage source to output 5V and record the channel value. Step 4. The recorded values are as follows: Voltage 1V 5V Standard Value 0 32000 Actual Value -55 31886 Error Value -55 -114 (Actual Value - Standard Value) Lower/ Upper Limit 0-(-55)= 55 32000-(-114)=32114 (Standard Value - Error Value) Step 5. Calculate the Analog Value Limits = Standard Value - Error Value Lower Limit = 55 Upper Limit = 32114 22 iR-AQ04-VI iR-AM06-VI iR-AI04-VI User Manual Step 6. Write values to the module: *At this point, the input value corresponding to a 1V voltage source is 0, and the input value corresponding to a 5V voltage source is 32000. Current Mode Calibration Analog Input Module 4-20mA Current Source Step 1. Channel parameter configuration: Set Input Mode to 4-20mA mode. Set Input Scale Range Upper Limit to 32000.
