Trial Run

1. Press the LOCAL/REMOTE key once. This puts the Drive in the Local Mode, allowing run/stop and speed commands
by the Digital Operator. The AUTO SEQ and AUTO REF indicators turn off, and the FWD light turns on.
2. Run the Drive at different frequencies and record monitor values. With the Drive in Local Mode, press the ENTER
key at Frequency Reference Monitor (U1-01). Use the UP, DOWN, and RESET keys to set the frequency reference.
Then, press the DATA/ENTER key to accept the frequency reference entered. Run the Drive at the set frequency
reference by pressing the RUN key. Use the UP and DOWN keys to view Output Current (U1-03), Output Voltage
(U1-06), and DC Bus Voltage (U1-07) while running the Drive throughout its entire speed range. Record the
following information at each speed:
Frequency
(Hz)
Monitor U1-01
6.0
10.0
15.0
20.0
25.0
30.0
35.0
40.0
45.0
50.0
55.0
60.0
When this table is complete, press the STOP key. The Drive will stop and the FWD light remains on. This step
provides benchmark data for the application from the initial start-up.
3. Press the MENU key once to display "Operation". Press the DATA/ENTER key to display "Frequency Ref".
If using a remote speed command, press the LOCAL/REMOTE key so the REMOTE SEQ and REMOTE REF
indicators are on. This puts the Drive in REMOTE mode.
4. If using an external speed command, determine whether the speed command is a 0-10Vdc or a 4-20mA signal.
Connect the positive side of a 0-10Vdc signal to terminal A1. Connect the positive side of a 4-20mA signal to
terminal A2. Connect the COMMON of the speed command to terminal AC.
Note: Connect only one input. The factory default is 0-10Vdc. To change to 4-20mA, adjust parameter H3-08
to "2: 4 – 20mA" and ensure DIP Switch S1-2 (located on the terminal board) is in the ON position.
