  The value of BFM #0 switches the analog output between voltage and current on each channel. It takes the form of a 4 digit hexadecimal number. The first digit will be the command for channel1 (CH1), and the second digit for channel 2 (CH2) etc. The numeric values of these four digits respectively represent the following items:
--* O=0: Sets the voltage output mode (-10V to 10V);
--* O=1: Sets the current output mode (+4mA to +20mA);
--* O=2: Sets the current output mode (0mA to 20mA);
--* O=3: Channel OFF;
--* O=4: Sets the voltage output mode (-10V to 10V);
--* O=5: Sets the current output mode (+4mA to +20mA);
--* O=6: Sets the current output mode (0mA to 20mA);
++O=0: Sets the voltage output mode (-10V to 10V);

--* Check that the external load resistance connected to each analog output terminal does not exceed the capacity of the LX3V-4DA drive (voltage output: 2kΩ to 1 MΩ / current output: 500Ω).
--* Check the output voltage or current value using a voltmeter or ammeter, and confirm that the output meets the I/O characteristics. If the output does not meet the I/O characteristics, adjust the offset and gain again. Refer to section 8.
