Product Description:
The SCE905NN-000-01 900 Servo Drive is an industrial automation product. It is designed by Pacific Scientific for motion systems that requires controlled servo operation.
The SCE905NN-000-01 900 drive uses a convection-based cooling method without an internal fan. This design allows silent operation and lower mechanical maintenance. It supports control logic input voltage from 90 to 264 volts AC. This wide voltage range enables flexible connection in control cabinets. The drive provides a peak output power of 18 kW at 480 volts AC. This level of output supports high-speed and challenging servo applications. The maximum input current for logic at 120 volts AC is 500 milliamperes. This low draw helps reduce power loss within the control circuit. The drive belongs to series 9 under the servo product group. It is programmed using standard software designed for basic drive functions. The model does not include communication or setup option cards. This provides simplified installation where advanced networking is not needed. The drive absorbs bus capacitance energy up to 80 joules. This energy rating applies at a 640V nominal bus sourced from 408 volts AC. This capability supports surge handling during load recovery or stop cycles. The minimum supported motor inductance at 240 volts AC is 1.9 mH. It helps prevent overcurrent conditions during motor start-up or rapid braking. The Pacific Scientific 900 drive supports basic motor control in demanding operations.
The SCE905NN-000-01 900 drive performs well in environments that requires minimal interface and consistent output. It is a functional choice for integration in standard motion control assemblies. The housing is structured for passive airflow across internal components. The setup offers clean mounting inside industrial electrical enclosures. The drive is suitable for machines running repetitive movement operations.
Frequently Asked Questions about SCE905NN-000-01:
Q: How does the drive handle surge conditions during load recovery?
A: It absorbs up to 80 joules of bus capacitance energy, effectively handling surge conditions during load recovery or rapid stop cycles. This capability ensures stable operation during power fluctuations without damaging internal components.
Q: What role does the minimum supported motor inductance of 1.9 mH play in the drive’s operation?
A: The 1.9 mH motor inductance threshold ensures compatibility with motors, preventing overcurrent conditions during motor start-up or rapid braking. This feature helps maintain safe and stable motor operation, especially during high-torque load cycles.
Q: What benefit does the 500 mA input current at 120V AC provide for the drive in terms of efficiency?
A: The 500 mA input current ensures that the SCE905NN-000-01 operates efficiently, reducing power loss within the control circuit. This leads to lower energy consumption and enhances the overall operational efficiency of the drive, especially in systems that require steady, reliable performance.
Q: Which feature of the SCE905NN-000-01 ensures it works efficiently in systems with varying voltage conditions?
A: With an input voltage range of 90–264V AC, the drive offers flexibility in connecting to different power sources. This wide range makes it compatible with multiple control cabinets and power standards across industrial applications.
Q: What advantage does the convection cooling system provide in the servo drive?
A: The convection cooling system eliminates the need for internal fans, resulting in quieter operation and reduced mechanical wear. This design also minimizes maintenance requirements, making it ideal for environments where silent performance and reliability are crucial.
