Page 17: Pid Control
Chapter 1 Introduction H Energy-saving Operation • The rotation speed of a three-phase induction motor does not decrease when the supply voltage drops if the motor has a light load. The 3G3HV Inverter in energy-saving operation automatically de- tects the current consumption of the motor connected to the Inverter, estimates its load, and drops the output voltage, thus saving the power consumption of the motor efficiently.

Page 44 Chapter 2 Installation D Installing a Magnetic Contactor If the power supply of the main circuit is to be shut off because of the sequence, a magnetic contactor can be used instead of a molded-case circuit breaker. When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly, however, the regenerative braking does not work and the load coasts to a stop.
Page 45 Chapter 2 Installation D Installing a Noise Filter on the Power Supply Side The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission.
Page 46 Chapter 2 Installation 2. Insert the short pin mounted on the board into the voltage connector nearest to the actual power supply voltage. The default setting is 440 V. The following example shows board of a 400-V Class Inverter of 18.5 to 45 kW. 380 V 400/415 V 440 V 460 V...
Page 47 Chapter 2 Installation D Installing a Thermal Relay This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set n033 to 0 (no thermal protection).
Page 48 Chapter 2 Installation D Countermeasures Against Radio Interference Radio noise is generated from the Inverter as well as the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.
Page 49: Ground Wiring

Page 50 Chapter 2 Installation H Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from industrial machines has been causing problems recently. Refer to the following for the definition of harmonics (i.e., harmonic currents with voltages) and countermeasures against the generation of harmonics from the Inverter. D Harmonics (Harmonic Currents with Voltages) •...
Page 51 Chapter 2 Installation • Inverter The Inverter as well as normal electric machines has an output current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine.

Page 53 Chapter 2 Installation D Countermeasures with 12-pulse Rectification against Harmonics Generation • 12-pulse Rectification The 3G3HV-series Inverter with an output of 18.5 to 160 kW can employ 12-pulse rectification, which suppresses harmonics better than reactors. The 3G3HV-series Inverter with an output of 15 kW or less and 185 kW or more cannot employ 12-pulse rectification.
Page 54 Chapter 2 Installation • Input Transformers for 12-pulse Rectification Refer to the following table to select the input transformer for 12-pulse rectification.

Page 82: Applied Operation
Chapter 3 Preparing for Operation Applied Operation 3-5-1 Energy-saving Mode The Inverter in energy-saving mode will automatically save unnecessary power supply to the motor if the load is light and the motor is a standard motor or dedicated motor for inverters.

Page 88: Pid Control Operation
Chapter 3 Preparing for Operation 3-5-2 PID Control PID (proportional, integral, and derivative) control is a method to control a mechanical system by making the feedback values obtained from the mechanical system agree with the set point that has been preset. This method makes it possible to control a mechanical system that has dead time.
Page 89: Types Of Pid Control
Chapter 3 Preparing for Operation D Integral Control The integrated deviation is obtained as control output from integral control. Integral control makes the feedback agree with the set point effectively. Integral control, however, cannot keep up with rap- id feedback changes. D Derivative Control The differentiated deviation is obtained as control output from derivative control.

Page 187: Notes On Using The Inverter For A Motor
Chapter 6 Appendix Notes on Using the Inverter for a Motor H Using the Inverter for an Existing Standard Motor When a standard motor is operated with the Inverter, power loss is slightly higher than when operated with a commercial power supply. In addition, cooling effects also diminish in the low-speed range, resulting in an increase in the motor temperature.
Page 188: Using The Inverter For Special Motors
Chapter 6 Appendix D Noise Noise is almost the same as when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz). H Using the Inverter for Special Motors D Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors.
Page 189 Chapter 6 Appendix H Motor Burnout Due to Insufficient Dielectric Strength of Each Phase of the Motor Surge occurs among the phases of the motor when the output voltage is switched. If the dielectric strength of each phase of the motor is insufficient, the motor may burn out. The dielectric strength of each phase of the motor must be higher than the maximum surge voltage.
