At 200 kHz, a typical 1,000-pulse/rev stepper drive runs at 12,000 rpm — well past the motor's torque curve, so the practical ceiling is the drive, not the module. Output format is NPN open collector transistor, so it sinks current to ground on each pulse. The load side — typically a stepper drive or servo amplifier — must provide the pull-up voltage (DC 5 to 24 V) and limit the ON current to 4.0 mA or more per the spec. ## Positioning units and range — fit for the axis type The module works in PLS (pulses), µm, 10⁻⁴ inch, or mdeg, with a range of -2,147,483,648 to 2,147,483,647 PLS. That 32-bit signed range gives ±2.1 billion counts — enough for a multi-revolution absolute axis with sub-micron resolution. Positioning method supports both incremental and absolute, selected per program. The unit magnification (1, 10, 100, 1000×) lets you scale the command unit to match the mechanical system without rewriting the ladder logic. ## Signal set for home return and interrupt positioning The FX3U-1PG carries dedicated DOG (proximity dog) and STOP inputs for machine home return and deceleration-stop operations. DOG input response time is 1 ms; STOP input is 4 ms — fast enough for most mechanical systems where the start-up time is 1 ms (motor) to 2 ms (mechanical). A CLR signal output clears the deviation counter on the servo drive at the home position, and a PG0 zero-point signal input synchronises with the encoder Z-phase for repeatable homing. Sourced to order against the BOM quantity through independent distribution.","metaTitle":"Mitsubishi FX3U-1PG Pulse Output Block, 200 kHz, NPN","metaDescription":"FX3U-1PG pulse output block for Mitsubishi FX3U PLC. 1 Hz to 200 kHz, NPN open collector, supports incremental/absolute positioning.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"RP":"Reverse rotation pulse or rotation direction signal","Unit":"PLS, µm, 10 -4 inch, mdeg","Range":"-2, 147, 483, 648 to 2, 147, 483, 647 PLS","title":"FX3U-1PG","Method":"Increment, Absolute","Weight":"0.2 Kg","Group 1 FP":"Forward pulse or pulse train","ON current":"4.0 mA or more","Group 1 DOG":"DOG type Used for interrupt input during DOG input or external command positioning during machine home return operation, interrupt 1st speed positioning, interrupt stop, interrupt 2nd speed positioning operation","Group 2 CLR":"CLR signal","OFF current":"0.5 mA or less","Product No.":"FX3U-1PG","Signal type":"NPN open collector transistor","description":"FX3U1PG POSITIONING MODULE SINGLE AXIS TRANSISTOR OUTPUT 8 POINT","Group 1 STOP":"Used for interrupt input during deceleration stop input or external command positioning, interruption 2-speed positioning operation","Group 2 PG 0":"Zero point signal input DOG type Used in machine home return operation","Product Type":"Pulse output block FX 3 U - 1 PG","Use altitude":"Can not be used in an environment pressurized to 2000 m or less under atmospheric pressure.
