Changing example
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 60)
Press to operate the inverter. (It is not necessary to
1. FWD
connect a motor.)
2.
Press to select the parameter setting mode.
MODE
3. Display the present running speed by pressing
read Pr. 900.
4. Press or to adjust the meter pointer to
a predetermined position. (Depending on the setting,
it may take some time until the pointer moves.)
REMARKS
1. Pressing to start reverse rotation operation will move the
REV
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.
5.
Press for about 1.5s.
SET
This completes the setting.
STOP
Press to stop the inverter.
6.
RESET
CAUTION
1. When the speed meter is connected across terminals DA1-5 to monitor the speed, the output of
terminal 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 60.)
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
• Calibration can be made also during external operation.
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)
