EM500 Open-Loop Vector Control Inverter User Manual 1. It’s strongly recommended to execute the trial operation with keypad under 2. Inverter can be used normally only after it has passed the idle trial operation and the terminal or communication control application. full-load trial operation. 5.2 Attentions for Trial Operation 5.2.1 Turn on the Power Switch Before turning on the power switch, please confirm the following items: Correct power voltage: 3-phase AC380 - 415V or 3-phase/single-phase AC220 – 230V, 50Hz 72 In case of ramp-to-stop, please confirm braking unit and braking resistor have been properly connected.
Check whether inverter runs normally and whether braking mechanism acts normally by switching forward and reverse operations with keypad. Observe whether inverter outputs corresponding frequency level by level through master controller’s sending of speed signal of all speed levels. Independent braking unit. Please observe whether the braking unit indicator is on. Inverter can start, run, stop, run forward and reverse, and perform other basic operations. In case of any abnormality, please check whether input and start/stop function codes are correctly set.
Basic Operation S Curve Often used for occasions of high-inertia drive system and occasions sensitive to acceleration to reduce mechanic shock and avoid system vibration. Nor Acceleration mal Per /Deceleratio Op for n erat ma Input DC current to motor before start or stop, in order to generate braking torque and thus rapidly stop the rotating motor. ion nce DC Braking Sett ing Special With multiple multi-function input and output ports, EM500 can offer various kinds of application solution when in use with external controller.
