The Mitsubishi LD75P1-CM is a single-axis positioning module from the LD75 series, rated for 200K pulses/s output and carrying 600 positioning data points per axis. It connects to a servo drive via open-collector output up to 2 m cable distance. This is a current-production part with a typical lead time of one to ten working days, which means it's readily specified for new builds or spares without obsolescence risk.
The 200K pulses/s output and 2 m cable limit restrict this module to short-range open-collector positioning. 600 data/axis means you can store 600 target positions, speeds, or dwell times per axis on the module itself. That's enough for a moderate sequence; beyond that, you'd need to stream from the PLC, which adds scan-time jitter.
