PR0112-S - 2-Axis Stepper Motor Controller

PR0112-S - 2-Axis Stepper Motor Controller

2-Axis Stepper Motor Controller

These high-performance motor controllers with integrated power output stage combine the most stable technology in a small package. The ramp generator is hardware-integrated into the motor controller and allows setting of trapezoidal as well as acceleration and braking ramps. Use of the encoder input allows the stepper motor to be operated with these motor controllers in a closed loop like a brushless DC motor. The controllers can be configured using software tools.
