VFD of SOFTSTARTER FOR ELECTRICAL MOTORS

Grounding Bush for VFD Driven Motors

When it is Essential to fit an Input Choke to Inverter Drives Small and Medium sized Drives without internal DC Chokes need a relatively soft supply, to keep the input Current within the design range. Use on a High Fault Level supply will have high rms and high harmonic Current. The Solution is to fit 1%, 2% or 4% Input Chokes. Medium to Large Drives with internal DC Chokes, need 1% minimum supply impedance, to complete protection of the front-end diodes/thyristors. If this not available in the supply, the Solution is to fit 1% (minimum) Input Chokes. An Input Choke reduces Voltage transients and other supply disturbances in a weaker supply, or Applications where a sliding busbar or brush-gear provides the incoming power supply. Voltage Drop of 9.2V, 4.6V and 2.3V approximately will be present across 4%, 2% and 1% Chokes. Excessive Voltage Drop will cause reduced torque available at the motor. If there is an option to fit an external DC Choke, Voltage drop will be reduced. References for 400V Drives: - WEG CFW100 0.18kW to 1.5kW. 1% Minimum Supply Impedance. Page 16 (3.2.3.2).

Programming for Schneider inverter ATV 320 to control an electric elevator. Before practical implementation, I implemented and simulated first using Yaskawa j1000 inverter. The following was required: 1) A program to control the elevator via selector button and specify a direction for forward and a direction for reverse, thus controlling it remotely from the terminal control circuit. 2) Control the frequency to a value of 40 Hz and control it locally. 3) Do ramping stopping and starting so that during start the motor ramps for 5 seconds and during stop press, ramping is done for 3 seconds. 4) DC injection operates at half the motor rated current for 5 seconds during start and 3 seconds during stop. 5) Use the button to create an eternal fault and use three different speeds to control the elevator speed.📝📝🧷♥

To test alternator diodes with a multimeter, set the multimeter to diode test mode. Connect the multimeter's positive lead to the alternator's output terminal and the negative lead to the alternator's case (ground). A good diode will show a low reading in one direction (typically 0.5-0.8 volts) and a high resistance or OL (open loop) in the reverse direction. Repeat for each diode.
