Working Principle The controller receives command signals from a host control system, compares them with real-time feedback signals from the motor encoder or resolver, and processes the error through a PID control algorithm. It then generates PWM (Pulse Width Modulation) signals to drive the power stage, adjusting the output voltage and current to achieve precise control of motor speed, position and torque.

Installation Requirements

• Mount vertically with at least 100 mm clearance on the top and bottom for ventilation
• Ambient operating temperature: 0°C to +45°C
• Storage temperature: -20°C to +60°C
• Relative humidity: 10% to 90% (non-condensing)
• Installation altitude: Up to 1000 m above sea level

Operation Notes

• Disconnect all power sources before performing wiring or maintenance
• Ensure proper protective grounding to avoid electromagnetic interference
• Do not operate the unit with the front cover removed
• Periodically inspect the heat sink and cooling vents for dust accumulation
• Do not exceed the rated motor current for continuous operation
