PARAMETER
(1) Analog output signal setting [Pr. 309]
Use [ Pr. 309 Analog output signal voltage/current
switchover ] to select whether to output the same
signal or different signals from terminal AM0 (analog
voltage output) and terminal AM1(analog current
output).
When [
Pr. 309 = 0, 10 ] , same signal is output from
terminal AM0 and AM1, and set the output signal
using [
Pr. 306 ]. (Refer to page 346 for output signal
description.)
When [
Pr. 309 = 1, 11], a different signal is output
from each terminal, and set output signal from AM0
using [
Pr. 310 ] and from AM1 using [ Pr. 306 ]. (Refer to
page 346 for output signal description.)
(2) Adjusting the meter needle to stop at 0 [Pr.
323, 324]
If the meter needle does not point to 0 when voltage
or current output is 0, use [
Pr. 323 AM0 0V adjustment ]
or [ Pr. 324 AM1 0mA adjustment ] to calibrate the meter.
Setting a smaller value decreases the analog output
and a larger value increases the analog output.
(3) Calibration of analog signal [C0 (Pr. 900), C1
(Pr. 901)]
When outputting the same signal from terminal AM0
and AM1 ([
Pr. 309 = 0, 10]), set [ Pr. 306 = 21]
(reference voltage output) and adjust the output at
full-scale using [C1 (
Pr. 901 )].
When outputting the same signal from terminal AM0
and AM1 ([
Pr. 309 = 1, 11]) , set [ Pr. 310 = 21]
(reference voltage output) for terminal AM0 and [ Pr.
306 = 21] (reference voltage output) for AM1 to adjust
the output from these terminals at full-scale using [C0
(
Pr. 900 )] and [C1 ( Pr. 901 )] respectively. Refer to
page 356 for details.
Calibrating AM 0 and AM1 without setting 21 in [ Pr.
306 ] or [ Pr. 310 ] calibrates terminal FM and AM of the
inverter. To prevent this, always set 21 before
calibrating terminal AM0 and AM1.
(4) Analog signal adjustment [Pr. 307, 308,
311, 312]
Use [ Pr. 307 ] or [ Pr. 311 ] to set for zero analog output
(meter points 0).
In addition, use [
Pr. 308 ] or [ Pr. 312 ] to set for
maximum analog output (full-scale).
Output signal value can be calibrated when [
Pr. 309 =
0, 1] and analog input value can be adjusted when
[
Pr. 309 = 10, 11].
* When [ Pr. 307 ] [ Pr. 308 ] and [ Pr. 311 ] [ Pr. 312 ] are set,
the output value at terminal AM0 and AM1 are always zero.
* When [ Pr. 307 ] [ Pr. 308 ] and [ Pr. 311 ] [ Pr. 312 ] are set,
the output value at terminal AM0 and AM1 are always the
parameter setting value.
