2. Set the data to be read to the driver of the slave address 2 as in the step 1.
Parameters having set in the unicast mode are cleared when the main power supply and the control
power supply are turned off because they are stored in RAM. If the “Write batch NV memory” of the
maintenance command is executed, parameters are saved in the non-volatile memory. Therefore,
they are retained even if the main power supply and the control power supply are turned off.
