Please note that when P2-08 is set to 10, the users cannot reset this parameter
.
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
