Description of stepper motor driver SMD-4.2 open frame
The SMD-4.2 stepper motor driver is manufactured in a frameless design, in the form of an open board with mounting holes. There is also a carrier kit version of the driver with a DIN clamp. The compact and lightweight driver is small in size and does not require much space at the installation site. The operation of the stepper motor with SMD-4.2 driver is characterized by low vibration and noise. The driver works with microstepping up to 1/256, provides high motor output torque.
Control methods of stepper motor driver SMD-4.2 open frame
- Pulse position control
Pulse position control of the stepper motor is provided by standard logic signals STEP/DIR and ENABLE. - Analog speed control
Analog stepper motor speed control can be done in two ways: - external voltage signal 0 - 10 VDC;
- built-in potentiometer.
