Description of stepper motor controller SMSD-4.2RS
The controller SMSD-4.2RS is a programmable device to control stepper motors with current per phase up to 4.2 A. SMSD-4.2RS supports both RS 232 and RS 485 communication interfaces. The unit is made in a plastic housing to be mounted on a standard DIN rail. The unitcontrol the direction, speed, acceleration of the stepper motor, and also operates according to complex algorithms (executive user program) recorded in non-volatile memory. The controller SMSD-4.2RS can operate autonomously, from a computer, PLC or other master device, receiving control commands via RS 232 or RS 485, or from an external master controller that performs impulse control of the drive.
Control modes of the controller SMSD-4.2RS
The controller provides operation in one of 5 main control modes:
- Autonomous operation according to a user program, which is recorded to it’s memory;
- Command control in real time;
- Pulse position control with logic signals STEP and DIRECTION;
- Analog stepper motor speed control.
Software for the programmable stepper motor controller SMSD-4.2RS
SMC-Program-Extended is used with SMSD-4.2RS-485 controllers for stepper motors. Communication interface and full command list are open and available in controller documentation. But for time saving, customers' support and convenience we offer ready software for easy work and fast execution programs assembling.
The software SMC Program Extended is used to assemble and writeuser programs to the controller and to control from a PC. The software is available for downloading at our website. The controller SMSD-4.2RScan receive and process signals from external devices and sensors in the program, as well as commands for sending signals to external devices. The controller also provides function and signal to search for the initial position.
SMC Program Extended allows a user to create stepper drive operation algorithms (user executive programs), write them to memory and read them from the controller's memory. Real-time control is also provided.
