Quick Start Guide
This guide is a step by step procedure to assist in installing and operating the inverter with a
motor to verify that they work properly. Starting, stopping, and motor speed will be initially
controlled from the keypad. After the initial check has been completed, the inverter may then be
configured for a particular application that may require external control or special systems
programming.
Step 1: Before starting the inverter
Safety First!
Please refer to Section 1
Safety precautions
, before proceeding.
Check inverter and motor nameplate to determine that they have the same HP and voltage
ratings. (
Ensure that full load amps of the motor does not exceed that of the inverter
.)
With power
OFF
, wire and verify that AC power is connected to L1(L), L2, and L3(N).
CAUTION -
For single phase power, apply only to terminals L1(L) and L3(N)
Wire and verify that the motor leads are connected to T1, T2, and T3.
When using a braking module, connect the terminal voltage of the braking unit to (P+ and N
–
) terminals on the inverter.
Step 2: Apply power to the inverter
Apply the appropriate AC power to the inverter and observe the keypad display. The 3 digit 7-
segment display should show the input power voltage for 3- 5 seconds and then show the
frequency command value of 05.0 (factory default). At this point the display will be
blinking. The
Power
ON
Indicator LED should also be
ON.
Step 3: Check motor rotations
without
load
On the keypad, press the
RUN
key. The display will be on steady and indicate 00.0 to 05.0,
which is the value of the inverter output frequency applied to the motor.
Verify the operation and direction of the motor. If the direction of the motor is incorrect, press
the
STOP
Key, and turn
OFF
the AC power. Before proceeding any further verify that the
Power Indicator LED on the inverter keypad is
COMPLETELY OFF
.
Swap the leads connected to the inverter T1 and T2 terminals. Go to Steps 2 and 3 and
recheck the motor direction.
Press the
STOP
key.
Step 4: Check motor full speeds at 50Hz/60Hz
On the keypad, change the inverter output frequency with the
,
arrows, and then press the
DATA/ENT
key to store the new value. In this case set it to 60Hz.
Press the
RUN /STOP
key, and observe the motor operation as it accelerates to full speed.
Press the
RUN/STOP
key, and observe the motor operation as it decelerates to 0 speed.
After satisfying the above, you can proceed with setting the application specific parameters and
permanent installation.
