ABB inverter is developed by ABB Group.Production.Sales of well-known inverter brand.Mainly used to control and regulate the speed of three-phase AC asynchronous motors, and with its stable performance.A wide range of combined functions.High-performance vector control technology.High torque output at low speed.Good dynamic characteristics and super overload capacity, occupy an important position in the inverter market.

abb inverter repair

Clean the air filter cooling air duct and internal dust.Check the screws.Bolts and that is, plug-in, etc. whether loose, input and output reactor to ground and phase resistance is not short-circuit phenomenon, normal should be greater than a few tens of megohms.Conductor and insulator whether there is corrosion, such as to wipe clean with alcohol in time.

abb inverter fault code

1. fault code for a; fault name is overcurrent that is OVERCURRENT; the problem is that the output current is too large for normal operation; solution measures by preventing motor overload.Increase the acceleration time.The problem is a very high DC voltage in the circuit; the solution is to reduce the static or transient voltage on the input side of the transmission power supply.Increase the deceleration time .Large chopper .Voltage controller in normal operation.

abb inverter wiring diagram

.
ABB inverter wiring diagram control principle: (1) Main circuit: to prevent the ABB inverter from generating electromagnetic waves that affect other circuits, a reactor is installed.(2)Control circuit: it is capable of manual type switching, so in the event of a fault, it has to be operated in a manual way.

Before operating the inverter is to be sure to carefully check its manual, otherwise some unnecessary injuries and dangers may occur.The manual explains in detail the steps and precautions for each step of the installation, including preparation for installation, selection of the location, removal of the front panel, installation of the inverter, wiring, checking the installation and putting the front panel back on and then powering up and starting.The model code on the inverter indicates the construction of the product, the output current rating, the voltage rating, and the enclosure protection rating.The instructions also include detailed key functions and specific display information for the assistant type control panel.It also includes some specific parameter modes and so on, and the back mainly includes notes on the failure analysis and maintenance of the inverter.
