Original Press Release:



First Time Ever Dedicated Voice Coil Actuator Amplifier/Controller Featuring 4-Quadrant Servo Control



San Marcos, Calif., October, 2002 - BEI Kimco Magnetics Division of BEI Technologies, Inc. has introduced the VCA 100. It is a new stand-alone PWM Servo Amplifier/Controller designed to maximize performance of BEI's linear and rotary Voice Coil Actuators. This versatile, 4-quadrant, DSP-based controller can operate as a position, velocity or force/torque mode amplifier/controller.

The VCA 100 is a programmable servo drive that uses the latest DSP technology to provide a powerful feature-set configurable via a RS232/485 port. It accepts digital and analog feedback signals and is capable of stand-alone operation or multi-axis integration, when connected to a PC-based distributed motion system.

Principal Features:
o User defined macro capability for motion sequencing and I/O processing.
o Pre-emptive multi-tasking command interpreter.
o User programmable S-curve and Trapezoidal motion.
o Variable servo rate up to 5 kHz.
o Current and position loop tuning via serial interface (no potentiometers).
o Drive setup and status information available serially via RS232 or RS485 link.
o Drive parameters and status history recorded in non-volatile EEPROM and available as diagnostic histogram.
o Accepts analog & digital feedback.
o Setup utility using a serial port interface on any P/C with Windows 95 or higher.
o Minimum Communications Level: Dumb terminal or embedded controller with ASCII characters.
