SMSD-1.5 stepper motor controller is designed to control small size stepper motors, output current is under 1.6 A per motor's phase. The controller provides 3 main control modes - programmable, analog speed control and STEP/DIR position control. Digital I/O of the controller make it easy to use the controller together with other electronics of a system.

Description of stepper motor controller SMSD-1.5
Control modes of the controller SMSD-1.5:
- Program mode - this mode is widely used for cycle and repetitive actions. The motion algorithm is recorded from a PC (via USB) to a non-volatile memory of the controller and afterwards it can be executed as per input signal or as per a command from a PC. Please, refer to the user manual for a full list of executing commands. Special software for program assembling and downloading to the controller is provided by our company for free;
- Analog speed control mode - it is used for smooth speed regulation without PC connection. The motor speed is proportional to analog voltage signal, potentiometer regulation is also possible. Direction and start/stop are controlled by digital inputs;
- Pulse position control STEP/DIR - the standard position control mode, motor speed is proportional to a STEP voltage signals frequency, displacement is proportional to a STEP signals quantity. Rotation direction depends on a voltage level at DIR input.
