The most desirable is the programmable mode. SMSD controllers under this control mode operate a

The other control mode – direct control mode – stepper motor drive with SMSD s per pre-loaded motion algorith. Motion algorithm is a sequence of simple commands like motion start, stop, speed, direction, acceleration and deceleration, movement distance, syncronization to outside devices and etc. Such algorithms are loaded to the controllers from a computer using ready software SMC-Program (provided with the controller for free) or any other software for data transfer. We provide fully data communication protocol and command list for our controllers. For PC connecting USB or LAN is used. Data transfer via simple and well known RS232. This control mode is convinient for automation systems with repeating operation cycle.

controller executes commands as soon as gets them from a computer. Such real-time control from a computer convinient if the motion parameters are changed often or are not known in advance.

Analog speed control mode – speed of a motor is controlled by analog voltage signal, direction by digital signal.

Analog position control mode – the defined position is proportional to the input analog voltage signal, the motion scale is set via communication data protocol.

The last control mode is the same as in simple stepmotor drivers – position is set by pulse signal. There are two modefications of this control mode: PULSE and DIR signals and A-phase and B-phase pulses with 90° difference.

CANopen control mode – all motion parameters are controlled via CAN interface, CANopen standard. It is the most suitable control mode for huge industrial systems, where different devices operates in conjunction.
