• PSU251 series is a serial signal interface unit for incremental linear scales.
• The interface outputs serial data equivalent to 400 divisions from the signal (sinusoidal).
• The PSU-251 can be connected to Mitsubishi Electric Corporation's MR-J4/ MR-J3 series servo amplifier.
• The PSU-252 can be connected to Panasonic Corporation, Motor business unit's MINAS series servo amplifier.
• Since this unit is connected to incremental linear scales, the reference point should be passed through to determine the absolute position.
