■ Other functions
1) Duty control by digital output
This function convert the output of external PID (analog amount: %) to PWM., and output it to the digital
output terminal. It can be used for ON-OFF control.
(PID3)
When [A340] is one of the value "1", "2", "11", "12", and [A359] is not "0", the result of external PID is
converted to PWM pulse whose period is set by [A359 (sec)], and output to the digital output terminal
"218/219".

When [A370] is one of the value "1", "2", "11", "12", and [A389] is not "0", the result of external PID is
converted to PWM pulse whose period is set by [A389(sec)], and output to the digital output terminal
