Product Description

The controller is made for operating Pacific Scientific Brushless Servo motors, Permanent Magnetic (PM) Brushless Servo motors and the other 3-phase. The SC402-016-T4 is a stand-alone and independent unit capable of 4 quadrant control of each PM Brushless Servo motor. It can be constructed with the servo motor as a velocity block or a torque block. The SC402-016-T4 can ensure high-frequency PWM current control to attain high level performance of the servo motor. Its careful design and multiple protection circuits of the SC402-016-T4 ensure trouble-free operation.

Significant features of the SC402-016-T4 include direct and stable 115/230VAC line operation. It has magnetically isolated output stage to ensure reliability and decrease crosstalk and ground loop turbulence. The SC402-016-T4 has MOV protected input circuitry. It’s multiple protection circuits and the integral fusing of the controller allows dynamic range adjustment. The SC402-016-T4 has the capacity to adjust peak current limit.

The SC402-016-T4 has multiple protection circuits including output fault, controller OT, DC Bus Fault, Control Voltage OK, and Motor OT. It can adjust input voltage 115/230 VAC (+10, - 15%) 1 or 3 phase, 47-63 Hz. The nominal Bus voltage for 230 VAC input is 320 VDC and for 115 VAC input its 160 VDC.

The output ripple frequency of the SC402-016-T4 is 20 kHz and fault output is 30 VDC and 25 mA sink. This controller is intended to be placed within a filing cabinet and it is of “open frame” design. It must be placed and ventilated by a conditioned or filtered air to avoid accumulation of dirt or dust on the electric components of controller. To ensure safety of the controller the air should also be free of electrically conductive contaminants, and free of corrosive air.
