For example, if users desire to observe the voltage signal in channel 1 and set this channel for
observing the pulse command frequency, when the pulse command frequency 2.25M corresponds
to 8V output voltage, users need to adjust the monitor output proportion of P1-04 to 50 (= 2.25M/
Max. input frequency). Other related settings include P0-03 (X= 3) and P1-03 (The polarity setting
range of monitor analog output is between 0 and 3, and it can set positive/negative polarity output).
Generally speaking, the output voltage of Ch1 is V
frequency × V /8) × P1-04/100.

Because of the offset value, the zero voltage level of analog monitor output does not match to the
zero point of the setting. This can be improved via the setting of offset adjustment value of analog
