H-28HMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.Pulse signal interface unit PSU-200SERIES 539•The PSU-200 splits the sinusoidal signal output by Mitutoyo linear scales into a minimum of four and a maximum of 200 divisions, and converts the signal to a square wave signal so that NC feedback systems, measurement control devices, etc., can be used with linear scales in order to achieve highly accurate positioning.Refer to the NC Linear Scale Systems (Catalog No.E13005) for more details.Serial signal interface unit PSU-200SERIES 539•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 amplier.•The PSU-252 can be connected to Panasonic Corporation, Motor business unit's MINAS series servo amplier.•Since this unit is connected to incremental linear scales, the reference point should be passed through to determine the absolute position.SPECIFICATIONSOrder No.539-005ModelPSU-200Number of axes1 axisInputInput connector DA-15S-N (JAE) or equivalentInput signal: 2-phase sinusoidal and the reference voltage,Reference point, Scale alarmOutputOutput connector: MR-20RMA (HONDA TSUSHIN KOGYO CO., LTD.)Output signal: 2-phase square wave signals (PA, PB), reference point (PZ), Alarm, Alarm reset, Photo-couplerNumber of splits4, 8, 10, 20, 40, 80, 100, 200 (Selectable with the switch)FunctionSetting the number of slits, setting the minimum edge interval, and maximum response speed.Detection of broken wires or short circuits and abnormalities (alarm), detection of signal errors (alarm).Power supply voltage low alarm (warning light only), switching between high-impedance mode and alarm signal output mode.
