Mitsubishi A1SD75P1-S3 1-Axis Positioning Module for MELSEC-A Series

The Mitsubishi A1SD75P1-S3 (A1SD75P1-S3) is a single-axis motion and positioning module engineered for Mitsubishi MELSEC-A series programmable logic controller systems. Designed for direct mounting on a compatible base plate or rack, this unit provides precise control for stepper and servo drive systems by generating command pulse trains. It delivers an output speed of up to 200,000 pulses per second via open-collector output and up to 400,000 pulses per second when using a differential line driver interface. Functioning as a dedicated axis controller, the module executes point-to-point positioning, speed control, and homing routines without burdening the main PLC CPU. It serves industrial machinery applications requiring accurate position tracking and velocity regulation, such as material handling, automated assembly lines, packaging machinery, and linear actuators. With its robust rack-mounted design, the unit ensures dependable signal transmission and high-speed operation within demanding factory automation environments.
