The 8D711F05PB is a self-contained, three-phase induction motor starter designed to control the start-up of three-phase induction motors. It has been designed with a flexible field programmable logic controller and various starter options to offer the professional user an economical solution for motor starting. The 8D711F05PB has a wide range of applications, including pumps, compressors, fans, and mixers, but is most commonly used in industrial machine tool applications.

The 8D711F05PB uses a programmable logic controller (PLC) to provide a wide range of features and functions that range from simple analog or digital signal control and monitoring to complex, multi-motor sequencing and control. The PLC is equipped with near-field communications (NFC) technology, allowing the user to easily configure the 8D711F05PB for a specific application. The integrated PLC also provides an economical means of motor control and operation.

The 8D711F05PB’s working principle relies on the motor’s speed and torque being increased by the addition of a control voltage to its three-phase winding. This is done by adding a source of control voltage, usually referred to as an auxiliary transformer, to the motor’s winding circuits which monitors the motor’s current, controlling its speed and providing a reliable and adjustable starting torque. The 8D711F05PB also incorporates a start/stop switch to control the motor’s operation, and a power source, typically a three-phase power line, that provides current to the motor.

Additional features of the 8D711F05PB include the ability to control multiple motors in parallel or in unison, as well as an adjustable starting current limit and variable run time. This allows the user to program the motor’s current to an optimal level for the specific application, while avoiding potential overloads of the motor or other connected components. Additionally, the 8D711F05PB’s design integrates various safety features and control logic to protect the motor in the event of a power outage or overload.

The 8D711F05PB is an excellent option for controlling the start-up of three-phase induction motors. It is a cost-effective, reliable, and easy to configure solution that is suitable for a range of motor applications. With its integrated PLC, NFC technology, and a wide range of motor protection features, the 8D711F05PB is an ideal choice for motor control and operation.
