User Manual EM303B General Purpose Inverter Setting Reference Frequency The default of inverter reference frequency is keypad VP potentiometer regulation. Before trial operation, please confirm the setting frequency of F0-00, and set the expected reference input frequency through VP potentiometer. Starting the Inverter 1. In function setting status, press JOG ＋／－ , inverter starts up as per setting value of F0-11(The default is 5.00Hz), and motor runs as per the direction set presently, please monitoring if it runs in a correct direction. 2. Press RUN on the keypad or turn the start terminal on, the motor runs to the setting frequency of F0-00 displayed. 3.
When reverse terminal is on, the motor reverses to setting frequency. 4. Press to adjust motor speed during running process (See 4.2.6 for reference.). 5. Press STOP RESET to enter ramp-to-stop status, the speed of motor decreases until the motor stops. Operation Status Monitoring 1. Change input frequency or rotation direction, and monitor if there is vibration or unexpected noise with the motor or not. 2. Check if inverter runs stably. 5.2.4 On-Load Operation After idling operation of motor is succeeded, please connect motor to the mechanical load for a trial operation. Connecting Motor to Mechanical Load 1.
After motor stops, turn off the power of inverter, and connect the motor to mechanical load. 2. Tighten up screw to locate the mechanical load onto the motor shaft. Starting up the Inverter 1. Start up the inverter in the same way as that in idling operation. 2. Set the frequency about 1/10 of the normal running speed. 3. Get ready for pressing STOP RESET in case of anything unexpected. Operation Status Monitoring 1. Monitor that the motor runs in the correct direction. 2. Increase frequency setting only after load mechanism is stable when running at a low speed. 3.
Change the input frequency or rotation direction of motor, and monitor whether there is vibration or unexpected noise with motor or not. 4. Monitor the parameters of C0-12 or C0-13 in running, and confirm whether the output current of the inverter is normal. 51
