P1 - 05 MON2

Analog Monitor Output Proportion 2 (CH2)

Communication Addr.: 0105H

Default: 100 Applicable Control Mode: P/S/T

Range: 0~100

Unit: %(full scale)

P4 - 20 DOF1

Offset Adjustment Value of Analog Monitor Output

(CH1)

Communication Addr.: 0414H

Default: 0 Applicable Control Mode: P/S/T

Range: -800~800

Unit: mV

P4 - 21

DOF2

Offset Adjustment Value of Analog Monitor Output

(CH2)

Communication Addr.: 0415H

Default: 0 Applicable Control Mode: P/S/T

Range: -800~800

Unit: mV

For example, when user wants 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 (X=3) and P1-03 (X=0~3, Output Polarity Setting). In general, when output voltage

value of Ch1 is V

, the pulse command frequency is equal to (Max. input frequency ͪ V

/8) ͪ P1-04/100.

Because there is an offset value of analog monitor output voltage, the zero voltage level of analog monitor

output doesn’t match to the zero point of setting value. We recommend users can use offset adjustment

value of analog monitor output, 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 exceed

its limit, it is still limited within the range of ̈́8V. The revolution provided by ASDA-A series is 10bit,

approximated to 13mv/LSB.
