Range Switching Function; D/A Conversion Enable/Disable Function; D/A Output Enable/Disable Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Range switching function

Switches the analog output range for each channel.
This function can change the output conversion characteristic by switching the range.
Setting procedure
In the "Output range setting", set the output range to be used.

After the data is written, the range is switched when the programmable controller power supply is turned offon or when the
CPU module is reset.
The range can be switched or the range setting can be monitored using the following buffer memory
addresses.
• 'CH1 Range setting' (Un\G598)
• 'CH1 Range setting monitor' (Un\G430)
For details on the buffer memory, refer to the following.

D/A conversion enable/disable function

Controls whether to enable or disable the D/A conversion for each channel.
Disabling D/A conversion for unused channels reduces the conversion cycle.
Setting procedure
Set "D/A conversion enable/disable setting" to "D/A conversion enable" or "D/A conversion disable".

D/A output enable/disable function

This function specifies whether to output the D/A conversion value or offset value for each channel.
The conversion speed is constant regardless of the output enable/disable setting.
Setting procedure
Set D/A output enable/disable for each channel by using 'CH1 Output enable/disable flag' (Un\G70, b1).
CH1 Output enable/disable flag (Un\G70, b1)
*1
Output enable (ON)
Output disable (OFF)
*1 When the CPU module changes from RUN to STOP, or a stop error occurs in the CPU module, the 'Output enable/disable flag' (Un\G70,
b1) turns off.
