FANUC A06B-6250-H018 servo amplifier

Basic information:
Brand: FANUC
Model: A06B-6250-H018
Type: Servo amplifier
Function description:
The FANUC A06B-6250-H018 servo amplifier is a device that provides a three-phase AC power supply with variable frequency for a servo motor. It can translate the instructions of the controller into the actual movement of the load, and is an indispensable key component in the field of industrial automation.
Internal working principle:
Rectifier and filter: First of all, through the three-phase full bridge rectifier circuit to the input three-phase or mains rectifier filter, get the corresponding direct current.
Inverter output: DC after rectification and filtering is output three-phase AC through three-phase sinusoidal PWM (Pulse Width Modulation) voltage inverter, which is used to drive three-phase permanent magnet synchronous AC servo motor.
Control logic: The inverter adopts a three-phase bridge circuit. According to the position of the servo motor rotor, the control circuit controls the on-off of each power tube (such as IGBT) of the inverter bridge to generate continuous torque.
Performance characteristics:
High efficiency: Through the pulse width modulation technology (PWM), the frequency and voltage amplitude of the output waveform can be accurately controlled to achieve the purpose of adjusting the power.
High reliability: The servo amplifier consists of a main loop and a control loop, which has undergone strict quality control and testing to ensure its high reliability and stability.
