2.15.6 Terminal DA1(FR-A7AZ) calibration [Pr. 857, C0 (Pr. 900)]
(A700)
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.
(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.
(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)
].
