AC300-C is a high-performance machine tool spindle frequency inverter newly developed by our company that adopts a brand-new motor control algorithm, book-type structure and independent cooling air duct. It combines the characteristics of the machine tool industry and strengthens the reliability and stability of the product aiming to meet the processing needs of different parts.
The beam pumping unit, commonly known as "kowtow machine", is the main equipment in oil pumping industry, of which the number reaches more than 100 thousand units. The total installed capacity of motor is 35 million kW, and the annual power consumption is over ten billion degrees. The power consumption of pumping unit is about 40% of the total power consumption in oilfields, and thus the efficiency is very low.
The wire drawing machine is important equipment for metal wire production and mainly for drawing the metal wire into various specifications of the filament. It means that the electrical control of wire drawing machine demands high standards. The frequency Inverter is the main part of the electrical control system, particularly the precision of tension control directly affects the quality and output of the product. VEICHI AC200L series wire drawing machine special frequency inverter by its outsta
For the current requirement that high-speed synchronous motor output usually exceeds 300Hz, AP100-K has a vector control algorithm up to 600Hz by using industry-leading vague PI control algorithm that could make sure fast regulation, no overshoot and fast response.
The wire and cable industry is currently moving toward higher technological levels such as product diversification, automation, etc. The power-discharging rack is very common in the wire and cable industry and it can be divided into vertical stand-off rack and horizontal stand-off rack according to the style. The racks are all line-out devices, but they are different in structure.
Slipping usually occurs at the start of the up-running, during the up-running and at the start of the down-running, and it always turns into the under-voltage fault
The servo drive produces cumulative error during normal operation
SD700 servo driver alarms during operation and the fault code is Er320
Fault Name:Damage to the inverter caused by the braking resistor. Fault Symptom: The inverter module is broken.
Fault Name:The output is abnormal after the touch screen is disconnected from the PLC.
Fault Symptom:After disconnecting the touch screen from the PLC, the inverter stops running and runs normally after being turned on.
Fault Name: OL2. Fault Symptom: The frequency inverter reports OL2 while running.
Fault Name: Blunt phenomenon in AC90 torque control operation caused by encoder feedback signal. Fault Symptom:AC90 was set to torque control in PG mode, but stop while blunting in operation.
