Product Description:

The Pacific Scientific company produces the SC723B00101 Servo Controller for industrial automation applications. It belongs to the SC720 Command Controllers series and uses a Series 7 configuration. It operates as a torque and velocity controller using a resolver-based encoder emulator. The unit features a 14-bit Resolver-to-Digital Converter with 4096 ppr resolution.

The SC723B00101 servo controller provides precision feedback with ±arcminute accuracy for tight motion control. The controller can support 7.5 amps continuous current at a rated thermal condition. It can provide a peak current of up to 15 amps in short periods. The servo controller features a personality module that is set by the factory to configure the drive according to standards. It is constructed as a standard model without custom modifications. The SC723B00101 servo controller supports ±5 V to ±12 V analog velocity input signals. The input impedance of this drive is designed to handle signals at 50 kΩ. The power-consuming dissipation is estimated at 35 watts when activated with 50 percent load operation. The fan provides internal cooling that necessitates the ventilation of the cabinet. The mounting needs no less than 10 inches of panel depth and vertical orientation.

The SC723B00101 servo controller has an operating ambient temperature specified from 0 °C to 50 °C. It can be used at 60 °C with reduced current output. The storage environment temperature range extends from -25 °C to +85 °C. Its altitude rating supports installation and usage up to 2000 m above sea level. The humidity should be non-condensing and kept below 95 percent RH. The spindle drive has to be installed on a low-vibration platform free of shock loads. The output connectors include J1 through J24 for power, command, and feedback.
