PR0125-S - Stepper Motor Controller

PR0125-S - Stepper Motor Controller

1-axis stepper motor controller, 6 A

This motor controller with integrated power output stage combine the most stable technology. 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 such as a brushless DC motor. The controllers can be configured using software tools.
