SC722A-001 Image 1


The SC722A-001 is a single-axis digital servo drive in the SC720 Series by Pacific Scientific. It features a robust design for high performance, providing a continuous current of 3.8A and a peak current of 7.5A. Servo controller characteristics include a 12-bit RDC option code with 1024 pulses-per-revolution (ppr). This device is capable of handling high voltage, exceeding 230VAC and 400VDC ratings. Incorporated within its design are cooling fans to prevent overheating during operation. The SC722A-001, for safety purposes, must not be powered with its chassis earth-grounded or without its cover. For a correct shutdown, the power supply should always be disconnected. This controller is specifically designed to function with Pacific Scientific's brushless servo motors. Storage for this device needs to be within a temperature range of -25C and +85C, with an emphasis on clean and dry environments. It is recommended to store the unit in its original shipping carton to prevent potential damage. Mounting this controller requires a vertical positioning within a 10-inch deep NEMA cabinet for industrial applications, using #10 or 1/4-20 bolts. The SC722A-001 employs seven input/output cables for establishing connections, of which the J1 motor cable connects the motor windings to the controller. Despite its comprehensive functionalities, it's crucial that power is disconnected during any phase of connection or reconnection. Lastly, to ensure proper operation, the resolver cable should be an isolated, twisted-shielded cable for the output pairs.

SC722A-001 by Pacific Scientific is a Single Axis Servocontroller unit in the SC720 Series. The SC722A-001 features a Power Level Code of 3.8A cont./7.5A peak along with a 12 bit RDC (+/- arcmin, 1024 ppr) Option Code. This Servo Drive also has a Function Code of torque/velocity controller w/encoder emulator (resolver) and a Customization Code of Standard Unit.
