2.15.6 Terminal DA1(FR-A7AZ) calibration [Pr. 857, C0 (Pr. 900)]
Calibration can be performed for the signal that is output from terminal DA1 ( bipolar analog voltage output) when the built-in
option FR-A7AZ is installed to the inverter.

CO(900) FM terminal calibration
(1) Adjusting the meter needle to stop at 0 [Pr.
857]
When the meter needle does not point 0 at 0 output
voltage, calibrate the meter with [Pr. 857 DA1-0V
adjustment ]
Analog output becomes smaller by making the
setting value smaller, and it becomes greater by
making the setting value larger.
Initial Value Setting Range
Adjustment can be made for the meter needle of the meter connected
1000% 900 to 1100%
to terminal DA1
— — Scale of the connected meter to terminal DA1 can be calibrated.

Description
(2) Calibrating analog signal [CO(Pr. 900)]
For the calibration of terminal DA1, set [Pr. 838 =21]
(Reference voltage output), and perform full scale
adjustment by [C0(Pr. 900)]. For the adjustment
method, refer to page 356.
If calibration is attempted without setting 21 in [Pr.
838] (Reference voltage output), calibration is
performed for the terminal FM of the inverter.
When using and installing both of FR-A7AZ and FR-
A7AY, and [Pr.309 Analog output signal voltage/current
switchover = 1 or 11] and [Pr. 310 Analog meter voltage
output selection = 21 ] are set, the terminal AM0 of FR-
A7AY is calibrated by [C0 (900)].
