Emerson EV2000 inverter repair center

.8 Lightning, induction or inductive lightning lightning lightning impulse voltage is formed, and sometimes cause damage to the inverter. In addition, when the power supply system on the primary side with vacuum circuit breakers, short circuit resulting in a higher closing impulse voltage. To prevent over-voltage impulse voltage caused damage, usually at the input side of the inverter plus varistors absorber. Vacuum circuit breakers should be increased RC surge absorber. If the transformer primary vacuum circuit breakers, should control the timing, ensure vacuum circuit breakers before the drive is disconnected first. 2 drive's self-diagnostic function and prevention of transistor inverter is mainly the old model has the following disadvantages: easy trip, is not easy to re-start, low overload capability. Due to the rapid development of IGBT and the CPU, the inverter increases the perfect self-diagnosis and fault prevention function, greatly improving the reliability of the drive. If you use a vector control inverter "all areas of automatic torque compensation function", where "insufficient torque", "decline in output caused by changes in environmental conditions" and the cause, will be well overcome. This feature is the use of a microcomputer inside the inverter speed, and calculates the torque required for the present time, the rapid correction of the output voltage and compensation at the inverter output torque changes due to changes caused by external conditions.
