Function List

Table3.2 shows the functions of the Q66DA-G.
Item
D/A conversion enable/ • Specifies whether to enable or disable the D/A conversion for each channel.
disable function • Disabling D/A conversion of unused channels can increase the conversion speed.
• Specifies whether to output the D/A converted value or output the offset value for
D/A output enable/dis- each channel.
able function • Regardless of the output enable/disable setting, the conversion speed is "6ms x
number of conversion-enabled channels".
Analog output HOLD/ • The output analog value can be retained when the programmable controller CPU is
CLEAR function placed in the STOP status or when an error occurs.
Analog output test during
• When CH
programmable controller
controller CPU STOP, the D/A converted analog value is output.
CPU STOP
Warning output function • A warning is output if a digital input value falls outside the setting range.
• The increase and decrease in analog output values per conversion cycle of one sta-
Rate control function tion (6ms) can be limited.
• Using this function prevents rapid change of analog output values.
• The resolution mode can be changed according to the application, and a resolution
setting can be selected from 1/4000, 1/12000 and 1/16000.
Resolution mode • The resolution mode setting is applicable to all channels in block.
• Refer to Section 3.1.1 for the digital input values and maximum resolution in normal
resolution mode and high resolution mode.
• The input range of digital values can be changed to any given range between -32000
Scaling function
and 32000.
• The module can be changed without the system being stopped.
However, if a module in the analog output range extended mode is replaced with a

module that does not support the mode, an intelligent function module switch error
occurs.
