Kremford Hyperdrive-3 Programmable

Stepper Motor Controller

The Hyperdrive-3 stepper motor controller is fully programmable with an extensive programming language to set speed, acceleration, number of steps, delay times, input / output control, and a comprehensive set of motor controls to provide powerful, yet simple, motor control. Full programming and control is provided over an industry standard RS485 serial interface at either 9600 or 57600 baud. The Hyperdrive-3 can be programmed remotely from a PC or PLC, or the program can be saved in non-volatile storage. The program can be automatically run on power up. The Hyperdrive-3 has two control modes: a step mode and a speed mode. A step profile consists of an acceleration phase, a constant speed phase, and a deceleration phase, where the entire motor move profile is constrained to take a specified and exact number of steps. On the other hand, a speed profile consists of an acceleration phase and a constant speed phase, where the speed may be varied in any size increments. Four isolated input lines and two isolated output lines allow the program to monitor and respond to external events that can control the motor actions.
