YASKAWA HV-75AP4 Magnetic Contactor

Product Description

Yaskawa HV-75AP4 is a Magnetic Contactor for Spindle Motor Winding Selection used with Yaskawa Σ-V (Sigma-5) Servo Drive Systems. It is designed to switch spindle motor windings automatically, allowing the servo system to operate efficiently over a wide speed range while maintaining stable torque output. It is commonly installed in CNC machine tools and spindle drive systems.

Note: Although some sellers describe HV-75AP4 as a "Servo Drive," it is not a servo amplifier/drive. It is a magnetic contactor used as a peripheral component for Sigma-5 spindle servo systems.
