Omron inverter Omron Omron Industrial Automation Group's industry group development, production and sales of the brand inverter. Omron Industrial Automation Industry Group is a leading industrial automation products and application of advanced technology, energy-saving multinational large factories, as part of Omron's global business, it has become a leader in the field of automation. Overview 3G3RX series inverter based on the increase in high-performance low-frequency high torque characteristics of the built-in programmable functions can deal with the new high-end applications, an optional long-life components, portable operation and maintenance program designed to meet the engineering and technical personnel dredgers site requires energy-saving phone, built-in EMI filter, and RoHS standards, environmental health trend products. Fault code: OU "OU" is over-voltage error. During operation, the inverter detects the main circuit overvoltage, 200V class: 400V detected when the level exceeds 410VDC: detects more than 820VDC. Measures as follows: ① regenerative capacity is too large (no braking resistor) ◆ need external braking resistor. ◆ Increase the deceleration time. ◆ action to prevent voltage drop stall about 10V (200V to 380V 400V grade level setting is set to 770V) inverter deceleration. ② regeneration process does not move (with braking resistor) ◆ the deceleration in the anti-speed function is set to be invalid. ◆ The automatic deceleration function is set to be invalid. ③ brake option wiring anomaly (with braking resistor) energy-saving textile machines, confirm the brake unit, braking resistor is installed correctly. ④ Check the inverter supply voltage exceeds the rated voltage. ⑤ braking resistor selection too (with braking resistor), the replacement of the right and power of the braking resistor resistance. ⑥ damage internal braking transistor inverter, the need to replace the drive.
