3.41.1 DA1/DA2 terminal calibration (Pr. 900, Pr. 901 )
Pr. 900 "DA1 terminal calibration"
Pr. 901 "DA2 terminal calibration"
(1) Calibration of DA1 terminal
1) Connect a meter (speed meter) across inverter terminals DA1-5. (Note the polarity. DA1 is positive.)
2) When a calibration resistor has already been connected, adjust the resistance to "0" or remove the resistor.
3) Set any of "1 to 3, 5 to 12, 17, 18, 21, 32 to 34 and 36" in Pr. 54.
When the speed, inverter output current etc. has been selected as the output signal, preset in Pr. 55, Pr. 56 or Pr.
866 the speed, current value or torque at which the output signal is 1500r/min.
At this 1500r/min or rated current, the meter is normally deflected to full scale.
4) When outputting the item that cannot achieve a 100% value easily by operation, e.g. output current, set "21"
(reference voltage output) in Pr. 158 and perform the following operation. After that, set "2" (output current, for
example) in Pr. 158.
(2) Calibration of terminal DA2
1) Connect a 0-10VDC meter (speed meter) to across inverter terminals DA2-5. (Note the polarity. DA2 is positive.)
2) Set any of "1 to 3, 5 to 12, 17, 18, 21, 32 to 34, 36" in Pr. 158.
When the speed, inverter output current or the like has been selected as the output signal, preset in Pr. 55, Pr. 56
or Pr. 866 the speed, current value or torque at which the output signal is 10V.
3) When outputting the item that cannot achieve a 100% value easily by operation, e.g. output current, set "21"
(reference voltage output) in Pr. 158 and perform the following operation. After that, set "2" (output current, for
example) in Pr. 158.
z When the item to be monitored is selected and set in Pr. 54 "DA1
terminal function selection" or Pr. 158 "DA2 terminal function
selection", the inverter is factory-set to provide a 10VDC output in
the full-scale status of the corresponding monitor item as
described in the section of Pr. 54 and Pr. 158. These parameters
allow the output voltage ratios (gains) to be adjusted according to
the meter scale. Note that the maximum output voltage is 10VDC.
(Terminal DA1 can also provide a -10VDC output.)
