Product Description:
Pacific Scientific SC903AN-044-01 is a servo drive that is made to provide reliable power control for motor-driven uses. The drive is part of the SC9 servo drive family, which makes control and interaction in automation processes easier. The servo drive is designed to cool itself through airflow and does not need a fan. This means it can be mounted on a panel and makes the best use of space.
At 25 °C, the SC903AN-044-01 servo drive has a constant current of 7.5 A and a peak current of 15.0 A. The input can handle 120/240 V AC in either single-phase or three-phase modes. The U, V, and W terminals offer three-phase motor control and give the motor output. There are special terminals for resolver input that make it possible to accurately sense the position of the motor. A black terminal block has I/O connections that let digital and analog signals work together for any reason. An LED that blinks when the bus is active shows the state of the DC bus. It comes with a seven-segment status panel that shows diagnostic codes and setup details. The servo drive can be programmed through either an RS-232 or a proprietary link, which makes sure that it is set up correctly. As an accessory, you can get a basic connector kit that meets normal installation needs.
The SC903AN-044-01 servo drive's output rate of 12/9 FLA at 50/60 Hz gives the motor a lot of options. The drive is about 12 inches long, 8 inches wide, and 3 inches high, which makes it easy to put in small spaces. The design has side flanges that make installing panels safe. For motor phases and resolver connections, the front interface has green terminal blocks that make connecting easier. The drive has ventilation slots that let air cool the product through convection.
Frequently Asked Questions about Sc903an-044-01:
Q: Why does SC903AN-044-01 support resolver feedback terminals for control?
A: Resolver feedback ensures accurate position and speed monitoring. It provides reliable motor synchronization that enhances performance accuracy and control precision in demanding drive applications.
Q: Does SC903AN-044-01 include a seven-segment status display for diagnostics?
A: Yes, the display indicates setup information and error codes. It simplifies troubleshooting and provides quick visual monitoring of the drive status during operation.
Q: Why does SC903AN-044-01 use convection cooling without a fan?
A: Convection cooling reduces the mechanical parts and maintenance. It provides silent operation and reliable heat dissipation through design-integrated ventilation slots.
Q: How does SC903AN-044-01 manage three-phase motor outputs?
A: Motor outputs are delivered through U, V, and W terminals. They provide a stable three-phase connection that supports efficient torque generation and consistent motor performance.
Q: Why does SC903AN-044-01 feature a bus active LED indicator?
A: The bus active LED provides an instant status of the DC bus. It helps technicians quickly assess operational readiness and fault conditions during system checks.
