1. INTRODUCTION OF HIVD-700GS INVERTER The Layout of Motor Drive Unit (Inverter) is as following figure 4.1. Figure 4.1 Layout of Motor Drive Unit (Inverter) The main circuit includes the converter as a rectifier of AC power, the reactor to decrease ripples of DC power, the condenser of big capacity and device to absorb the regenerating current on braking resistor, and IPM DSP (Digital Signal Processing) inverter changing from DC voltage to AC voltage of variable voltage(VV) and variable Frequency(VF). And the control circuit consists of the vector operation part using the micro-processor and sine wave PWM (Pulse Width Modulation). VVVF (Variable Voltage Variable Frequency) elevator system adopted the inverter unit with the micro-processor based PWM (Pulse Width Modulation) control system for its simultaneous control of the voltage and frequency. With VVVF elevator system, the power consumption especially during the acceleration is greatly reduced compared to the primary voltage control elevator system of the conventional AC elevators. As the VVVF elevator system supplies the most optimum voltage and frequency to the motor continuously, the efficiency of the motor in speed and torque has been highly improved. 4-1 On Board Power Supply : 3 Phase-440V-60Hz (Input Power Waveform) Elevator Control Panel INVERTER (Output Power Waveform) Traction Motor (3 Phase-360V-51Hz) Figure 4.2 Configuration of Output Power Waveform by Inverter 2. HIVD-700GS INVERTER CHECK-UP Before checking the inverter, turn off NFB1 for main power feeding and confirm that the discharge lamp in the inverter is Off. 2.1 Check-Up of Wiring at Motor Drive Unit 1) Verify that the input power (3 phase 440V, 60Hz) is same as incoming power to Inverter (Terminal Name R, S, T). 2) Be careful for wiring of input line R.S.T and output line U.V.W not to be changed and check the wiring and connection. 4-2 Figure 4.3 Wiring of Inverter Input / Output Cable 4-3 2.2 Wiring for Rotary Encoder 1) For wiring of rotary encoder lines, confirm the signal of each line and do wiring.

Reconfirm the wiring of encoder cable lines before electrical power On. 3) Shielded cable should be connected to the bus-bar for field ground in control panel. 2.3 Wiring for Thermistor in Motor 1) NTC (Negative Thermo Coupler) Thermistors are provided in the motor winding for vector controlling by inverter. 2) If the thermistor line (THC, TH1) is not connected, starting shock of traction motor may be happened. Confirm the wiring of thermistor line before electrical power On. Figure 4.5 Wiring between Thermistor and Inverter 4-5 3.
