Basic operation (Speed setting, run,
speed meter adjustment)
3.2.2 Adjustment (calibration) of speed meter (meter)
At the preset speed of 1500r/min, make adjustment so that the meter (analog meter)
deflects to full-scale. Calibrate the DA1 terminal (±10V).(in PU operation mode)
POINT
• Pr. 900 "DA1 terminal calibration" can be read by setting "1" (extended function parameter enable) in
Pr. 160 "extended function selection".
• Set Pr. 900 "DA1 terminal calibration".
• Set any of "1 to 3, 5 to 12, 17, 18, 21, 32 to 34 and 36" in Pr. 54 "DA1 terminal function selection" to
output a signal to the terminal DA1. (Refer to page 56)
CAUTION
1. When the speed meter is connected across terminals DA1-5 to monitor the speed, the output of ter-
minal DA1 is saturated if the maximum output speed reaches or exceeds 1500r/min, with the factory
setting unchanged. Hence, the setting of Pr. 55 "speed monitoring reference" must be changed to the
maximum output speed. (Refer to page 56.)
2. Terminal DA2 can be adjusted in Pr. 901
3. For operation from the parameter unit (FR-PU04V), refer to the instruction manual of the FR-PU04V.
REMARKS
• For monitor display changes by , refer to page

.
• Calibration can be made also during external operation.

Operation
Press to select the parameter setting mode.
Display the present operation speed by pressing to
read Pr. 900.

Parameter setting complete!!
Press to operate the inverter. (It is not necessary to
connect a motor.)
Press or to adjust the meter pointer to
a predetermined position. (Depending on the setting,
it may take some time until the pointer moves.)
Press for about 1.5s.
This completes the setting.
REMARKS
1. Pressing to start reverse rotation operation will move the meter pointer
reversely (in the negative direction).
2. The terminal DA1 output will also keep displaying the monitor when the
inverter stops due to an alarm.
