Description of stepper motor controller SMSD-4.2LAN
Smooth stepper motor operation with SMSD-4.2LAN controller
Analog speed control by internal or external potentiometer or analog voltage signal 0..5V. Speed regulation with PWM signal is also possible. When using an external PWM signal, the motor speed is proportional to the effective voltage level applied to the SPEED input. (Recommended PWM signal parameters: F >= 5 kHz, amplitude 5V).
Control modes of SMSD 4.2LAN controller:
The controller provides operation in one of 5 main control modes:
- program mode - autonomous operation in accordance with one of 4 user programs stored in memory
- direct control mode - real-time command control
- analog speed control
- analog positioning control - adjusting of the angle
- pulse position control using "STEP" signals and "DIRECTION"
Additional digital inputs and outputs of the controller provide easy and fast connection to other electrical elements of the system
Functions and capabilities of the stepper motor controller SMSD-4.2LAN:
- Remote control of stepper motor via Ethernet network;
- Autonomous operation and control of a stepper motor according to one of 4 independent programs stored in the controller's memory;
- Real-time stepper motor control by commands from a PLC or computer via Ethernet or USB;
- Software control of the relay;
- Pulse position control with standard signals "STEP", "DIRECTION" and "ENABLE";
- Analog speed control: using external or built-in potentiometer or analog voltage signal 0..5V;
- Analog motor rotation angle control: using external or built-in potentiometer or analog voltage signal 0..5V;
- Function of memorization of the current position and transition to the memorized position is provided;
- It is provided to stop the motorif receive an emergency signal;
- It is provided to change the direction of rotation of the motorif receive a reverse signal;
- Synchronization of actions of several controllers is provided by external input and output signals and special commands;
- Motor control parameters (phase current, holding current, microstepping, control mode) are configured using an external panel and the unit's menu, or via a communication interface (Ethernet or USB);
- Control of input voltage — if the value of the supply voltage goes beyond the permissible values (less than 20 V or more than 51 V), the controller generates an alarm signal;
- The controller has an internal braking circuit with the ability to connect an external braking resistor;
- The sound signal of critical situations is provided;
- The controller has a built-in two-digit seven-segment indicator for setting, displaying critical situations and modes of operation of the controller;
- A 32-bit password is used to protect access over the local network with an authorization interval of 1 s (136 years for brute-force search of password options.
Software and parameterization of the stepper motor controller SMSD-4.2LAN:
It is possible to use open communication protocol or ready software for stepmotor controllers`SMSD 4.2LAN. The software SMC-Program Ver.5 provides connection and control of few devices connected via Ethernet or USB interface.
To set up and control the controller via Ethernet or USB, we provide an open communication data exchangeprotocol. Also we provide free software SMC-Program-LAN. The software allows to connect the controller via Ethernet or USB, manage operation, read and write user executive programs to the controller's memory, change control settings and motor parameters, as well as read and change data transmission settings via TCP/IP. To work with the drive, the software provides two control modes -real time control (Direct control) or recording a sequence of commands in the controller's memory (Program control).
