Product Description

The model SC453-804-05 is a Programmable Brushless Servo Controller designed for high performance motion control. It offers precise position and speed regulation across various applications. It supports flexible integration and accurate system control operations with compact design and versatile interface options.

This Pacific Scientific SC453-804-05 servo controller supports position control up to 100,000,000 steps with a resolution of 4096 steps per revolution and 15 arcmin accuracy. The speed control is supported from 0 to 10,000 rpm with a fine resolution of 0.01 rpm. The acceleration and deceleration range spans from 3 to 1,000,000 rpm/second, resolved at 3 rpm/second. The torque is controlled from 0 % to 100 % of peak current using a potentiometer. The non volatile memory allows 10,000 write operations for storing settings. The input commands such as Jog+, Jog– and Start/Stop are sampled every 1.024 milliseconds. The mechanical home switch and position loop update also operate at a 1.024-millisecond period. The device communicates via RS-232 or RS-485 interfaces with selectable baud rates including 1200, 2400, 4800 and 9600. It uses 10 bit data format (8 data, 1 start, 1 stop) with no parity. The input voltage of the controller include 115/230 VAC (± 10 %, – 15 %), supporting single or three phase systems at 47 – 63 Hz.

The bus voltage of the SC453-804-05 servo controller is 320 VDC for 230 VAC input and 160 VDC for 115 VAC input. The efficiency of this model is over 90 % at rated continuous power. The form factor remains under 1.01 that is ideal for space constrained environments. The current loop bandwidth reaches up to 3 kHz. A velocity offset function is included and adjustable to zero. The controller’s fault output is open collector rated at 30 VDC and 25 mA sink current.
