PLC User's Manual - Analog Control Edition
FX3U-4DA (4-channel Analog Output)
•For FX3G, FX3U, FX3UC Series PLCs
*1. The output mode setting, setting of corrective function by load characteristics and status automatic
transfer function setting are retained in the EEPROM of FX3U-4DA. For this reason, even if the
sequence program is deleted, the previously set functions will still be valid.
*2. After setting the output mode, set the data writing time (waiting time) to 5 seconds or more for each
setting. After the output mode is specified, and the same output mode is used, it is not necessary to
set the output mode and the waiting time (T0 K50).
