3. Test Run
3-1 Preliminary Check and Preparation
Perform the following checks before starting operation.
(1) Check that the inverter is correctly wired.
Most importantly, the inverter output terminals, U, V, and
W should not be connected to a power source and the
earth terminal should be correctly grounded.
(2) No terminal or exposed live part should be short-
circuited or grounded.
(3) Check for loose terminals, connectors, and screws.
(4) Check that the motor is disconnected from mechanical
devices.
(5) Turn all switches off so that the inverter will not start or
malfunction when powered on.
(6) After power-up of the inverter, check that:
1) the KEYPAD panel gives indications as shown in
Figure 3-1-2 (no alarm message), and
2) the inverter contained fan is rotating.
(However, when the function code H06 “Cooling fan
ON-OFF control” is used, there may be a case where
the built-in fan is stopped.)
· Never turn the power switch on (closed) before mounting the face cover. Do not remove the cover while
the inverter is energized.
·
Do not handle the inverter with wet hand.
Doing so may lead to electric shock.
3-2 Operating Methods
There are many operating methods. Read this manual and select the one most suitable to the intended use
and operating conditions. General operating methods are described in Table 3-2-1.
3-3 Test Run
After checking that no abnormal condition exists in 3.1, perform
a test run.
Before delivery, the inverter is programmed to be operated from
the KEYPAD panel (with function code F01 set to 0 and F02 to 0).
(1) Turn the power on. Check that the speed indicated by
blinking LEDs is 0r/min.
(2) Set the speed to a lower level around 100r/min using the
key.
(3) Press the key to run the motor in the forward
direction or the key to run in the reverse direction.
Press the key to stop the motor.
(4) Check that:
1) the motor runs in the selected direction (see Figure 3-3-1),
2) it revolves without any problem (motor roars and excessive
vibration), and
3) it smoothly accelerates or decelerates.
If no abnormal condition is observed, raise the operating
speed and check again. If the inverter is found to normally
function in the test run, start regular operation.
