SC755B-001-01

SC755B-001-01 is a Pacific Scientific servocontroller in the SC750 Servo Drives series. It is a standard unit with a programmable digital position controller for motion and positioning tasks. Resolver feedback supplies motor position data, while the drive accuracy is ±4 arcmin. The option detail is +4 arcmin, indicating the positive angular accuracy limit. The controller includes 24K of user memory for storing user-created control routines and parameters.

The drive provides 30 A of continuous current and 60 A of peak current. Its continuous output power is 9 kW, while its peak output power is 18 kW, or 18,000 W. The bus operates at 320 VDC with an RMS bus current of 29 A and can absorb 50 J of bus energy. A transformer rated from 5 to 7.5 kVA is recommended to supply the required power.

The supported motor line-to-line inductance range extends from a minimum of 0.5 mH to a maximum of 130 mH. The shunt handles 200 W continuously and up to 20 kW at peak to dissipate regenerative energy. Maximum drive power dissipation is 300 W. Natural convection and built-in fans remove operating heat, and the unit weighs 18.16 kg.
