For example, when the users want to observe the analog voltage signal of channel 1, if
the monitor output setting range is 8V per 325Kpps, then it is needed to change the
setting value of parameter P1-04 (Analog Monitor Output Proportion 1) to 50
(=325Kpps/Max. input frequency). Other related parameters setting include parameter P0-
03 (A=3) and P1-03 (A=0~3, output polarity setting). In general, when output voltage
value of Ch1 is V1, the pulse command frequency is equal to (Max. input frequency ×
V1/8) × P1-04/100.
Because there is an offset value of analog monitor output voltage, the zero voltage level
of analog monitor output does not match to the zero point of setting value. We
recommend the users can use Analog Monitor Output Drift Adjustment, DOF1 (parameter
P4-20) and DOF2 (parameter P4-21) to improve this condition. The maximum output
voltage range of analog monitor output is ±8V. If the output voltage exceeds its limit, it is
