4.5 Monitor Selection
Use Pr.98 and Pr.99 to select desired variables that you wish to monitor.
Enter MONITOR mode using LOCAL Panel:
Select
MON
mode by push
CTL/MON
key.
Pushing the CTL/MON key will change the mode between
CTL
and
MON
mode.
It is easy to distinguish that when
any one of Hz or I lamp is ON
, the inverter is under
MON
mode; if
Hz or I lamp
all OFF
, the inverter is under
CTL
mode.
The

keys are used to select the desired variable shown on 7-segment display for monitoring.
4.6 Simple application example
4.6.1 Input Motor Parameters
If the Input Line voltage is 220V, and the motor in use is
Rated Voltage 200V
Rated Frequency 50Hz
Rated Current 9Amp.
Maximum output frequency 80Hz is desired
Choose inverter model PDA-2037 (220V, 11Amp).
Then, set the following parameters according to above conditions:
Pr.95=0 and Pr.96=1, allow parameter change
Pr.10=50.00Hz, set motor Rated frequency
Pr.11=91%, set motor Rated voltage 91%=(200V/220V)*100%
Pr.15=80.00Hz, set maximum output frequency
Pr.88=100%, set maximum output voltage at maximum frequency
Pr.78=82%, set the percentage of motor rating to inverter rating 82%=(9Amp / 11Amp)*100%
Refer to Sec.4.2

Set up procedure for above application:
l
Pr.39=1.1 Determines the control command input from terminals
l
Pr.40=25.00 Determines the set frequency may come from Panel-VR (AI3) or Pr.00
l
Pr.00=60.00Hz Set predefined output frequency in Pr.00
l
Pr.01=2.0Sec. Set desired acceleration time from stop to maximum speed
l
Pr.02=2.0Sec. Set desired deceleration time from maximum speed to stop
l
Pr.03=73 Select DI5 as RUN function
l
Pr.04=74 Select DI6 as REV function
l
Pr.41=36 Select DI1 as timer input
l
Pr.42=88 Select DI2 as Frequency source switch (the function should combine with Pr.40). If DI2=OFF,
frequency source come from Panel-VR, else if DI2=ON, frequency source come from Pr.00
l
Pr.45=43 Select DO1 as timer output
l
Pr.71=20.0 Select timer ON/OFF period is 20seconds
Explanation:
l
Define an auto ON/OFF timer with period equal 20seconds, using DI1, DO1 and Pr.41, 45, 71.
l
When switch SW1 ON, starts inverter and enables the timer.
l
The timer output will control motor forward or reverse and repeat every 20swconds.
l
For the first 10seconds period, the inverter runs at 60Hz(Pr.00) reverse;
l
For the second 10 seconds period, the inverter runs in forward direction with frequency determined by Panel-VR.
l
When switch SW1 OFF, inverter stops.
