Quick Start Guide

This guide is to assist in installing and running the inverter to verify that the drive and motor

are working properly. Starting, stopping and speed control will be from the keypad. If your

application requires external control or special system programming, consult the 7300EV

Instruction Manual supplied with your inverter.

Step 1 Before starting the inverter

Please refer to chapter one (Notice for wiring) of the 7300EV Instruction Manual. If you feel

this was abnormal, do not start the drive until qualified personnel have corrected the

situation. (Failure to do so could result in serious injury.)

• Check inverter and motor nameplates to determine that they have the same HP and voltage

ratings. (Ensure that full load motor amps do not exceed that of the inverter.)

• Remove the terminal cover to expose the motor and power terminals.

a. Verify that AC power is wired to L1(L), L2, and L3(N) .

b. Verify that Motor leads are connected to T1, T2, and T3 .

c. IF brake module is necessary, please connect terminal voltage of the braking unit to +

and - of the inverter.

Step2 Apply power to the drive.

Apply AC power to the drive and observe operator. Three 7-segment display should show

power voltage for 3~5 seconds and then show Frequency Command, factory sets 5.00.

(Frequency Command of 7-segment display should be flashed all the time.)

Step3 Check motor rotation without load. Press RUN Key. 7-segment Display will indicates 00.0to 05.0. Such value is the frequency output value. Check the operation direction of the motor. IF the direction of the motor is incorrect: Press STOP Key, turn off the AC power supply. After Power indicator LED is off, change over theT1 and T2. Supply the power again, then check the motor direction. Press STOP key.

Chapter 1 Notice for wiring 1.1 Fuse types Drive input fuses are provided to disconnect the drive from power in the event that a component fails in the drive’s power circuitry. The drive’s electronic protection circuitry is designed to clear drive output short circuits and ground faults without blowing the drive input fuses. Below table shows the EV input fuse ratings. To protect the inverter most effectively, use fuses with current-limit function.
PAGE 5
1.2 Precautions for peripheral applications: Power supply: Make sure the correct voltage is applied to avoid damaging the inverter. A molded-case circuit breaker or fused disconnect must be installed between the AC source and the inverter. Molded-case circuit breaker: Use a molded-case circuit breaker that conforms to the rated voltage and current of the inverter to control the power and protect the inverter. Do not use the circuit breaker as the run/stop switch for the inverter.

3.2 General functional troubleshooting Status Checking point Corrective Action Is power applied to L1, L2, and L3(N) terminals (is the charging indicator lit)? ‧ Is the power applied? ‧ Turn the power OFF and then ON again. ‧ Make sure the input line voltage is correct. ‧ Make sure all terminal screws are secured firmly. Are there voltage outputs on T1, T2, and T3 terminals? Motor does not run Is the motor mechanically overloaded? Turn the power OFF and then ON again.
