4-7 Test operation (V/f control mode)
When finished with automatic tuning, test run the isolated motor, and make sure that there are no
errors.
Use the following procedures to test the operation with the operation panel.
Refer to Chapter 3 for details on using the operation panel.
The case that the maximum frequency (B-004) and base frequency (B-005) are 50Hz is shown here.
CAUTION
To prevent incorrect operation during the test operation, make sure that signals are not input
into the sequence input terminal.
1) To enable operation with the operation panel, confirm that the "LCL" LED is ON. If not, press the
LCL
SET
+
STOP
keys, and confirm that the "LCL" LED turns ON.
2) Set speed setting input point selection: C02-0= 3 (panel fixed).
CAUTION
The motor will rotate with the next step.
Confirm the safety around the motor before starting the next step.
3) Press the
RST
MOD
and display D00-0 on the monitor. Then press the
key. Operation will start.
The "FWD" lamp will turn ON, and the display will change from "
" to a value display. The
value will gradually increase, and after several seconds, will change to "
". This is
because as the factory settings, the direct setting frequency (A00-0) is set to 10Hz and the
acceleration ramp time 1 (A01-0) is set to 10sec.
CHECK
1. Did the motor run?
2. Is the run direction correct? Check the wiring and operation if abnormal.
3. Is the rotation smooth?
4) Press the
key and confirm that the motor runs in reverse.
(Note)
Do not carry out this step if a load which cannot be run in reverse is connected.
5) Press the
key and stop the motor.
6) Press the
key. The motor will forward run at the output frequency 10Hz.
Change the frequency to 50Hz with the following operation.
7) Press the
RST
MOD
key several times. The Display will alternate between "
" and
"
" (with the U30 V24OP1, the
0
section of "A00-
0
: 10.00Hz" will flicker).
8) Press the
LCL
SET
key once.
The display will stop at "
", and the last digit will flicker.(With the U30 V24OP1, the
flicker will move to the 2nd decimal digit of the furequency display.)
This completes the preparation for changing the output frequency. The digit to change can be
moved with the
key. The output frequency can be incremented/decremented with the
keys (
knob with U30 V24OP1).
