4.1.1 Inspection and Preparation Prior to Operation
Check the following prior to starting operation.
(1) Verify correct connection.
Carefully verify that the motor power cables are connected to drive output terminals U, V and W and that the
ground cable is connected to the ground electrode correctly.
WARNING
• Do not connect power supply wires to the drive output terminals U, V, and W. Otherwise, the drive may be dam-
aged if you turn the power on.
• Be sure to connect the ground leads of the drive and the motor to the ground electrodes.
Otherwise, electric shock may occur.
(2) Check for short circuits between terminals and exposed live
parts and ground faults.
(3) Check for loose terminals, connectors and screws.
(4) Check if the motor is not connected to a driven load.
(5) Turn all switches off so that the drive does not start or operate
erroneously at power-on.
(6) Check that safety measures have been taken against runaway of
the system, e.g. a defense to protect people from unexpectedly
approaching your power system.
4.1.2 Turning on Power and Checking
WARNING
• Be sure to install the terminal cover before turning the power on.
Do not remove the cover while power is turned on.
• Do not operate switches with wet hands.
Otherwise electric shock could occur.
Turn the power on and check the following points.
This example shows when no function code data is changed from
the factory setting.
(1) Check that the LED monitor displays “0.00” (meaning that the set
frequency is 0 Hz) and is flashing. (See Figure 4.2)
If the LED monitor displays numbers other than “0.00,” turn
the potentiometer to set “0.00” as the set frequency.
(2) Check that any built-in cooling fan is functioning normally
(for models with 2 hp and above).

4.1.3 Preparation before Running the Motor for a Test – Setting Function Code Data
Before initial running of the motor, set the function code data specified in Table 4.1 to the corresponding motor
rating and for your system design values. For motor information, check the rated values printed on the nameplate of
the motor. For your system design values, check with the system designers.
