AC300-C machine tool spindle frequency inverter

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.

Application of AC300 general frequency inverter on power-discharging rack

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.

The elevator slips of low voltage inverters

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

Damage to the inverter caused by the braking resistor

Fault Name:Damage to the inverter caused by the braking resistor. Fault Symptom: The inverter module is broken.

Blunt phenomenon in AC90 torque control operation caused by encoder feedback signal

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.

The main contactor coil is burnt out

Fault Name: The main contactor coil of the lifting machine is burnt out.Fault Symptom: The power on of the all-in-one cannot be run after starting, and the under-voltage fault is reported.

Principle of hardware speed tracking circuit in frequency inverter

Our AC70 series inverters all have hardware speed tracking function. After the inverter stops, the motor can start directly and smoothly before the motor stops rotating. How does the hardware and software cooperate to achieve this function? The principle will be explained in detail below.

Solution of under-voltage fault while running

Fault Name: Reporting under-voltage fault while runningFault Symptom:The frequency inverter runs normally, but it would report the under-voltage fault with the load after starting.

Solution of the problems in constant pressure water supply system of AC70

Fault Name:Analysis of problems occurring in constant pressure water supply system of AC70 frequency inverterFault Symptom:AC70 frequency inverter does not sleep on the constant pressure water supply system, the water pressure is too high, the pressure fluctuates and other issues.

Solution of oc1 and oc3 fault

Fault Name:OC1 or OC3 is reported in the AC70E frequency inverter.Fault Symptom:The AC70E reports the OC1 or OC3 fault when starting and running, and if you remove output line, same problem happens and the field device cannot continue to run.

Solution of overload fault

Fault Name:OC1 or OC3 is reported in the AC70E frequency inverter.Fault Symptom:The AC70E reports the OC1 or OC3 fault when starting and running, and if you remove output line, same problem happens and the field device cannot continue to run.

Solution of under-voltage fault

Fault Name:AC70 low-power frequency inverter cannot drive the high-power motor to run even without any load.Fault Symptom:2.2KW frequency inverter starts to run in VF control mode, 5.5KW motor runs abnormally or even shakes, then it reports overload fault.
