Stepless stand alone drive SVM

Servo drive stepless SVM stand alone

Stepless is the technology invented and developed by CMZ for low speed applications.

Through the closed loop control, a stepper synchronous motor can be controlled with modulated current by:

eliminating any problem due to the step loss

reducing the motor temperature.

Compared to the brushless solution, on the same motor size the Stepless technology provides higher torque at low speed. This makes it most suitable for a wide variety of low speed applications.

SVM is also featuring:

internal programmability
CANOpen, PROFIBUS, MODBUS RTU protocols
usability with all master controllers using CODESYS.
