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
325 Kpps corresponds to 8V output voltage, users need to adjust the monitor output
proportion of P1-04 to 50 (= 325 Kpps / 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
1
; the pulse command frequency is (Max. input frequency × V
1
/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 monitor output, DOF1 (P4-20) and DOF2 (P4-21). The voltage
level of analog monitor output is ±8V, if the output voltage exceeds the range, it will be
limited within ±8V. The provided resolution is about 10 bits, which equals to 13 mV/LSB.
