Features: 17-bit and 23-bit absolute photoelectric encoder, with high quality and high responsiveness; Speed: Good speed characteristics, typically the rated speed can reach 3000 rpm, and the maximum speed can reach 6000 rpm; Adaptability: Strong overload resistance, can withstand a load three times the rated torque, especially suitable for cases with instantaneous load fluctuations and the need for rapid start-up; Stability: Smooth operation at low speeds, during low-speed operation there will be no step-like operation phenomenon similar to stepper motors. Suitable for cases requiring high response speed; Timeliness: The dynamic response time during acceleration and deceleration of the motor is short, usually within tens of milliseconds; Comfort: Significantly reduced heat and noise.Product CharacteristicsModelVoltage (VAC)Current (A)Torque (Nm)Weight (kg)Body Length (mm)MD57BLY1S85-24-00230-1R00124V2.8A0.16 85.5MD57BLY1S105-24-00330-1R00124V5.6A0.32 105.5MD57BLY1S125-24-00530-1R00124V8.4A0.48 125.5MD57BLY1S145-24-C00630-B1-4-1R24V11.2A0.64 Motor Technical SpecificationsItemSpecificationWinding connection methodStar connectionEncoder type17-bit absolute encoderShaft runout - outside0.025mmRadial clearance0.06mm@450gAxial clearance0.08mm@450gMaximum radial load15N@20MM from flangeMaximum axial load10NInsulation classB classDielectric withstand voltage500VAC for 1 minuteDielectric resistanceMinimum 100 Ohm, 500V DCInsulation resistanceMinimum 100 Ohm, 500V DCMotor ModelMD57BLY1S85 – 24 – C00230 – B1 – 4 – 1RMD57BLY1S105 – 24 – C00330 – B1 – 4 – 1RMD57BLY1S125 – 24 – C00530 – B1 – 4 – 1RMD57BLY1S145 – 24 – C00630 – B1 – 4 – 1RRated voltage (V)24242424Rated power (W)50100150200Rated current (A)2.85.68.411.2Rated torque (Nm)0.160.320.480.64Peak torque (Nm)0.480.961.441.92Rated speed (rpm)3000300030003000Maximum speed (rpm)4300430043004300Line resistance (Ohm)0.780.350.20.16Line inductance (mH)1.820.830.540.42Torque coefficient (Nm/A)0.0570.0570.0570.057Body length (mm)85105125145Protection levelIP65IP65IP65IP65Motor insulation classClass BClass B Wiring DefinitionCN1TerminalNameFunction1GroundDC power groundDC24 – 36V power supply, reverse connection will damage the driver2DC+DC positive power CN5TerminalNameFunction1D01+Output terminal 01The function of this terminal depends on the user's I/O function settings.2D01-Output terminal 01 3D02+Output terminal 02 4D02-Output terminal 02 8DI1Input terminal 01 5DI2Input terminal 02 6DI3Input terminal 03 7DCCommon terminal for input terminals, used to control input optocouplers.
