Product Description:

The SC103010Y4 Servo Controller is a product of Pacific Scientific which offers a compact design with a form factor of less than 1.01 that ensures space efficiency in electrical panels and it allows velocity offset that is adjustable to zero which provides flexibility in tuning motor control.

The SC103010Y4 controller supports velocity input command in ±10 V bidirectional or 4–20 mA unidirectional format that is selectable using a jumper and its torque or current limit is set using a potentiometer that ranges from 10% to 100% which helps in controlling the maximum motor torque. This servo module voltage monitor provides ±7.5 V feedback that corresponds to the full output voltage level for real-time diagnostics and it also features a fault output that operates through a 24 VDC 250 mA relay contact that opens on fault detection to ensure safe shutdown. It provides a continuous stall output current of 15 A that supports sustained torque without thermal overload and is able to manage a continuous stall output power of 4.5 kW that allows compatibility with high-performance servo motors. It has 30 watts of continuous shunt regulator which assist in absorbing regenerative energy and maintaining bus voltage stability and it is designed to function with a 3 phase input that ensures balanced power delivery and improved performance.

This SC103010Y4 Servo Controller bus voltage is maintained at a nominal 320 VDC that ensures consistent voltage supply for efficient motor operation and makes it suitable for integration into industrial automation systems where precise motor control is required. Its input and output capabilities support integration with standard control systems that require accurate velocity and torque management which makes it a suitable choice for OEMs and system integrators looking for dependable servo control.
