Product Description:

PACIFIC SCIENTIFIC manufactures the SA602-001-01. The PACIFIC SCIENTIFIC SC900 series SA602-001-01 servo drive is designed for high-performance motion control in industrial automation. It has a max output current of 60A for 5 seconds, which is important for high-inertia starters and quick load transients. This transient current capacity improves system response and dynamic behavior by allowing the drive to sustain the motor’s torque surge demands at critical points like acceleration and sudden direction changes. Its continuous output current rating of 30A at 50°C with forced air cooling complements this. This continuous current defines the drive’s steady-state electrical and thermal limits and is key to how much torque the motor can produce over long periods of operation.

The SA602-001-01 has a wide range of electrical inputs, including DC 130- 370V and single-phase AC 90-264V at 47- 440Hz. This allows for seamless integration across industrial installations and international power standards where power source fluctuation is common. The power stage is supported by the internal DC bus voltage of 320V, which controls the drive’s energy throughput and switching behavior. The drive has 97% power stage efficiency at continuous rating, which reduces heat dissipation and stress on thermal management systems. The internal control circuitry only requires 15- 30W to regulate the power stage modulation, feedback processing and integrated control logic with minimal impact on overall energy consumption.

To provide ultra-high resolution positional feedback of 0.0013 arc minutes per rotation, the drive has a 24-bit resolver feedback. In closed-loop systems that require motor shaft alignment and smooth motion profiles, this level of accuracy is critical. With proper impedance and EMI control, the 50m cable length support allows for more deployment flexibility without degrading signal quality. The operating ambient temperature range of 0°C to 60°C proves environmental ruggedness, and certifications like UL Recognized-508C, CSA equivalence and ISO 9001 compliance prove durability and global safety and quality standards. It’s also perfect for high-speed speed high-accuracy applications in modern manufacturing and automation because of its 1 kHz operational control bandwidth, which means it can react quickly to control commands and disturbances.
