EM500 Open-Loop Vector Control Inverter User Manual 5. Trial Operation 5.1 Trial Operation Procedure Follow the steps in table 5–1 for trial operation of EM500 inverter. Table 5-1 Steps of Trial Operation 70 Step Description Check the power of inverter and install inverter as per requirements in Chapter 2. Installation Inverter Wiring Wiring as per the requirements in Chapter 3.
Verify that input power is connected correctly and the input power supply circuit is already connected to the circuit breaker; inverter is grounded; the power line is connected to inverter power supply input terminals R, S and T; motor is properly connected to output terminals U, V or W of inverter; the braking resistor is connected between + and PB; the control circuit is properly connected and all limit switches and brake control terminals are connected. Check before Power-on Check whether there is abnormal sound, foreign odor, fume or the like condition of inverter. Check whether power indicator is on and whether operation panel displays normally or there is no fault alarm.
In case of abnormality, please cut the power and check it as per Chapter 9. Power-on Check Parameter Setting Setting of macros (if any). Please input the nameplate parameters of motor driven by inverter and check the input carefully, or else serious problems may occur during running. Set the parameters of motor 1 in F01 group. When two motors are used in parallel, then motor rated power (or rated current) will be sum of that of these two motors.
To switch between two motors, user needs to set motor 2 parameters of F14 group Correctly Input Motor Nameplate Parameter Protection Parameter Properly set inverter and motor limit parameters and protection parameters, mainly including maximum frequency, upper limit Setting of Motor and
