1. Product designation
Programmable step motor controller SMSD-1.5 is designed to operate with stepper motor with maximum
current per phase up to 1.6 Amp. There are three control modes provided: programmable, manual or
simple driver.

2. Functions and possibilities
Recording the operation algorithm from a computer to EEPROM of the unit as a sequence of ASCII
commands.
Reading the saved algorithm from the EEPROM to a computer.
In the programmable mode: control the stepper motor as per the program, saved in the unit’s memory.
Speed, acceleration/deceleration, displacement, direction of the stepper motor are set as a sequence of
execution commands and is storage in the nonvolatile memory of the unit.
In the simple driver mode: the unit receives logic signals “PULS” and “DIR” – 0VDC low level and 824VDC high level.
In the manual mode: the unit receives analog signal “Speed” (voltage signal 0-5VDC, internal or external
potentiometer) and digital signals “Reverse” and “Enable”.
For synchronized operation of several SMSD-1.5 units and other devices there are 3 digital inputs and one
output relay are provided. These inputs and output relay are used in the programmable mode.
The unit can operate and be controlled by a computer or in a standalone mode.
There is zero positioning function provided: start zero search by a command or by a signal on the digital
input. Stop zero searching movement as input signal is received. The function provides homing by an
individual input.
The unit stops motor motion as receives a signal on an “Enable” input.
The unit changes rotation direction as receives a signal on a “Reverse” input (in the manual and
programmable modes).
The microstepping can be changed on-fly in the manual and programmable modes.
