PARAMETERS
NOTE
• When outputting such an item as the output current, which cannot reach a 100% value easily by operation, set Pr.54 to "21"
(reference voltage output) and calibrate. 1440 pulses/s are output from the terminal FM.
• When Pr.310 Analog meter voltage output selection = "21", the terminal FM calibration cannot be performed. For the
details of Pr.310, refer to the Instruction Manual of FR-A8AY.
• The wiring length of the terminal FM should be 200 m at maximum.
• The initial value of the calibration parameter C0(Pr.900) is set to 1 mA full-scale and 1440 pulses/s terminal FM pulse train
output at 60 Hz. The maximum pulse train output of terminal FM is 2400 pulses/s.
• When connecting a frequency meter between terminals FM-SD and monitoring the running frequency, it is necessary to
change Pr.55 to the maximum frequency, since the FM terminal output will be saturated at the initial value when the
maximum frequency reaches 100 Hz or greater.
• Calibration with the calibration parameter C0(Pr.900) cannot be done when Pr.291 Pulse train I/O selection = "10, 11, 20, 21,
100" (high-speed pulse train output).
Calibration procedure for terminal FM when using the operation panel
(FR-DU08)
NOTE
• Calibration can also be made for the External operation.Set the frequency in the External operation mode, and make
calibration in the above procedure.
• Calibration can be performed during operation.
• For the operation from the parameter unit, refer to the Instruction Manual of the parameter unit.
Operation
1.
Screen at power-ON
The monitor display appears.
2.
Changing the operation mode
Press to choose the PU operation mode. [PU] indicator is lit.
Calibration is also possible in the External operation mode.
3.
Parameter setting mode
Press to choose the parameter setting mode. (The parameter number read previously appears.)
4.
Calibration parameter selection
Turn until appears. Press to display .
5.
Selecting the parameter number
Turn until (C0(Pr.900) FM/CA terminal calibration) appears. Press to enable the parameter
setting. The monitored value of the item (initially the output frequency) selected by Pr.54 FM/CA terminal function
selection will appear.
6.
Pulse output via terminal FM
If stopped, press or to start the inverter operation. (To monitor the output frequency, motor connection is not
required.
Calibration is also possible in a stop status.
7.
Scale adjustment
Turn to move the meter needle to a desired position.
8.
Setting completed
Press to enter the setting. The monitored value and flicker alternately.
 Turn to read another parameter.
 Press to return to the display.
 Press twice to show the next parameter.
