Here are some details about the Servo amplifier in the Okuma BLII-D50/50A controller:

1. Basic overview

Function: Servo amplifier is a key component in the servo system, providing a variable frequency three-phase AC power supply to the servo motor, converting the command of the controller into the actual movement of the load.

Function: On CNC machine tools, the servo amplifier controls the speed, position and torque of the servo motor by receiving instructions from the CNC (computer numerical control) system, so as to achieve accurate control of the machine tool.

2. Technical features

Control mode: The closed-loop control mode is usually adopted, and the precise control of the servo motor is ensured through the feedback mechanism.

Drive components: The servo amplifier drives the servo motor, which usually has the characteristics of high precision and high response speed.

Power processing: The servo amplifier contains components such as rectifiers, filters and inverters, which convert the input three-phase AC into a three-phase AC suitable for the servo motor drive.

3. Application scenario

Industrial machinery: widely used in a variety of industrial machinery and equipment and automated production lines, such as CNC machine tools, robots, automated production lines, etc.

Automation equipment: In the plastic, textile, footwear, food, chemical, security and medical machinery warehouse and other industries, servo amplifiers also play an important role for automatic detection, counting, testing, protection and limit and position control.

4. Precautions

Selection and matching: When selecting a servo amplifier, it is necessary to ensure its matching with the servo motor, controller and other components to ensure the overall performance of the system.

Maintenance and maintenance: Check and maintain the servo amplifier regularly to ensure its normal operation and avoid failure and damage.
