Braking motor A-15 E6581381 When using a braking motor, if the braking circuit is directly connected to the inverters's output terminals, the brake cannot be released because of the lowered starting voltage. Therefore, when using a braking motor, connect the braking circuit to the inverter's power supply side, as shown in the figure below. Usually, braking motors produce larger noise in low speed ranges. Note: In the case of the circuit shown on the below, assign the function of detecting low-speed signals to the RY and RC terminals. Make sure the parameter is set to (factory default setting). Measures to protect motors against surge voltages In a system in which a 400V-class inverter is used to control the operation of a motor, very high surge voltages may be produced. When applied to the motor coils repeatedly for a long time, may cause deterioration of their insulation, depending on the cable length, cable routing and types of cables used. Here are some examples of measures against surge voltages. (1) Lower the inverter’s carrier frequency. (2) Set the parameter (Carrier frequency control mode selection) to or . (3) Use a motor with high insulation strength. (4) Insert an AC reactor or a surge voltage suppression filter between the inverter and the motor. 1.4.2 Inverters Protecting inverters from overcurrent The inverter has an overcurrent protection function. The programmed current level is set to the inverter's maximum applicable motor. If the motor used has a small capacity, the overcurrent level and the electronic thermal protection must be readjusted. If adjustment is necessary, see 5.12, and make adjustments as directed. Inverter capacity Do not use a small-capacity (kVA) inverter to control the operation of a large-capacity motor , no matter how light the load is. Current ripple will raise the output peak current making it easier to set off the overcurrent trip. 1
1 Power factor correction capacitor A-16 E6581381 Power factor correction capacitors cannot be installed on the output side of the inverter. When a motor is run that has a power factor correction capacitor attached to it, remove the capacitors. This can cause inverter malfunction trips and capacitor destruction. Inverter U/T1 V/T2 W/T3 Operating at other than rated voltage IM Remove the power factor correction capacitor and surge absorber Power factor correction capacitor Connections to voltages other than the rated voltage described in the rating label cannot be made. If a connection must be made to a power supply other than one with rated voltage, use a transformer to raise or lower the voltage to the rated voltage. Circuit breaking when two or more inverters are used on the same power line. MCCB1 MCCB2 MCCB3 MCCBn+1 (circuit breaking fuse) INV1 Breaking of selected inverter There is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than one inverter is used on the same power line, you must select interrupting characteristics so that only the MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1). When you cannot select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the INV1. If power supply distortion is not negligible If the power supply distortion is not negligible because the inverter shares a power distribution line with other systems causing distorted waves, such as systems with thyristors or large-capacity inverters, install an input reactor to improve the input power factor, to reduce higher harmonics, or to suppress external surges.
