SMSD‑4.2LAN - programmable stepper motor controller

The SMSD 4.2LAN is capable of receiving commands via Ethernet TCP/IP, enabling it to be connected to a local network for remote control of the drive. This controller offers five control methods: real-time control through commands, program mode, STEP/DIR, analog speed control, or position control.

Two versions of firmware are available for the controllers SMSD-4.2LAN – standard and Modbus TCP/IP. Modbus communication is provided for LAN connection. USB communication is the same as the base model.

The SMSD-4.2LAN stepper motor controller ensures smooth motor operation. It allows for analog speed control using either an internal or external potentiometer or an analog voltage signal in the range of 0 to 5 volts. Additionally, speed regulation via PWM signal is possible. When an external PWM signal is used, the motor's speed is directly proportional to the effective voltage level applied to the SPEED input.

The SMSD-4.2LAN controller offers operation in one of five primary control modes:

• Program Mode: This mode allows for autonomous operation based on one of the four user programs stored in memory.
• Direct Control Mode: Real-time command control.
• Analog Speed Control.
• Analog Positioning Control: This involves adjusting the angle.
• Pulse Position Control: This mode uses "STEP" signals and "DIRECTION."

Furthermore, the controller is equipped with additional digital inputs and outputs, making it easy and efficient to connect with other electrical components within the system.
