Product Description:
The SC725A-001 Servo Controller by Pacific Scientific is a digital drive unit from the SC720 Series. It is specifically built for controlling the brushless servo motors of Pacific Scientific, especially those in the R and F series. This drive uses a three-phase 230 VAC input supply. It operates with line frequencies of either 50 Hz or 60 Hz.
The SC725A-001 servo controller draws 29 amps under full load conditions. The controller supports stable motor performance with precise velocity regulation through an analog signal input. In terms of physical structure, the drive requires 12 inches of enclosure depth. It weighs approximately 40 pounds. The vertical mounting is required for this servo controller. It has a minimum clearance of 4 inches (10 cm) above and below the unit for proper fan-assisted cooling. The bolt pattern matches standard NEMA enclosures to allow for simple panel integration. This SC725A-001 servo controller offers a modular structure and includes a personality module for setup and adjustment. The module allows tuning of essential motion control parameters such as velocity loop gain, current limit, and velocity offset. This tuning system enables tailored motor operation for specific application needs. It accepts analog input signals in the ±5V to ±12V range. The drive uses a 50 kΩ input resistance for the control signal. This ensures accurate command interpretation from external controllers.
The SC725A-001 servo controller maintains full rated current output in ambient temperatures up to 50°C. At 60°C. The output is reduced to 70% of the rated value to prevent overheating. The system dissipates 300 watts of heat when operating at maximum rated current. It is useful for thermal planning and ventilation design. This servo controller ensures reliable operation and flexible configuration across various industrial automation applications.
