1 ontact Details efore using the product, please check the For latest information, DF catalogs and operation manuals M Series ositioning Motors <pplications> Machining centers' units, N lathes' turrets, automatic loaders, pallet changers, constant feed devices, etc Nomenclature Features Hydromechanical positioning hese positioning motors integrate Daikin's original hydromechanical rotary positioning system developed based on orbit motors known for low noise and high-torque at the low-speed range. Integrated compact unit ll the components for the required mechanisms of rotation, deceleration, and rotary positioning are joined with no piping and integrated into one compact unit. Quick positioning doption of a deceleration cam system and mechanical valves, in addition to quick response features, achieves appropriate speed reduction under the load conditions, enabling shockless stops in a short time without indexing errors. High-accuracy positioning he number of indexing positions can be selected from three options - 1 position, 2 positions or 3 positions over a full revolution - while the positioning cam groove can be selected from two options: highly accurate (±.1 ) groove V and groove R with backlash for supplementary positioning. Simple control & easy operation Simple on/off control of solenoid valves achieves easy operation of the positioning motor. Flexible feed pitch selection he capability to set the feed pitch as required enables smooth multi-pitch feed.

5 ontact Details efore using the product, please check the For latest information, DF catalogs and operation manuals If operation fails More than 9% of operation failures are caused by the fixed throttle becoming clogged with contamination. (See the sectional structural diagram for the location of orifice.) Motor not rotating or rotating slowly lean each orifice with clean oil and blow it with compressed air. (Do not wrap orifices with sealing tape when reassembling.) Replace the solenoid valve for rotation (spool type/operation type: 2). Indexing error lean each orifice with clean oil and blow it with compressed air. (Do not wrap orifices with sealing tape when reassembling.) Replace the solenoid valve for pin engagement/disengagement (spool type/operation type: 9). Handling Installation void crosswise drive of a belt, chain, etc. because it will cause large radial loads. lways drive the load via bearing support by using pillow blocks, for example. When driving a motor with a spur gear fitted at the end of the shaft, keep the load within 4.5 kn {45 kgf} (2.25 kn {225 kgf} for M5) including the radial load. If the load exceeds this limit, drive it via bearing support by using pillow blocks, for example. Ensure that the eccentricity of the drive shaft and motor shaft is no greater than.5 mm (IR). ighten the screw in the M8 tapped hole (depth of 2 mm) at the shaft end within a tightening torque of 2.5 to 3 N m {25 to 3 kgf cm}. efore replacing the motor, be sure to stop the hydraulic supply and check that there is no remaining pressure within the hydraulic circuit. Never disassemble the motor. Never use damaged hoses or old hoses for piping. Use hoses with sufficient pressure endurance range. When mounting the motor, securely fix it to the flange or base while being careful not to drop it and avoiding subjecting it to any impact with a hammer, etc. In addition, do not use the motor as a step. When connecting fittings on the motor, tighten them with an appropriate torque. ightening them with an excessive torque may cause breakage of the block or other parts. Set the key on the motor shaft without any looseness. Ensure that the clearance between the key and the wall of the key groove is no greater than.3 mm and securely fix the top part of the key using a screw or other means. Do not apply any load exceeding the permissible radial load (4.5 kn {45 kgf}) or the permissible thrust load (3.5 kn {35 kgf}) on the motor shaft. Do not hit the motor with a hammer, especially on the motor shaft. It will cause fluid leakage from the shaft sealing or damage to other parts. When using the front mount type, take care not to trap the O-ring. During piping work, take necessary measures to prevent dust or cutting chips getting in the piping or motor. Flush pipes before using them in piping work. When connecting the motor directly to a load part, accurate centering is required. Do not expose valves and sensors to water or impacts. Do not pull the detection rod or proximity plate with excessive force, or bend them. e careful to connect motor pipes correctly. Do not use the products in an environment susceptible to rust. Hydraulic oil Use a petroleum-based hydraulic fluid. Do not use other types of hydraulic fluid or mix different types of hydraulic fluid. Use hydraulic fluid within parameters where all of its specification conditions are satisfied at the same time. ositioning motors are not designed to handle combustible fluids or hazardous fluids. If such fluids are used and leak, the potential hazards include fire, disease, and environmental contamination. Recommended hydraulic fluid: Fluid equivalent to ISO VG32 to 56 Recommended viscosity range: 15 to 4 mm 2 /s {cst} ermissible fluid temperate range: to 6 ontamination: Within NS class 12 (Use a line filter with a filtration accuracy of 25 μ or better.) Running Do not touch the rotating part while the motor is rotating because it is very dangerous. e sure to provide a guard for the rotating part. If an abnormal pressure that exceeds the maximum operating pressure of the motor can be expected, install a safety valve together with the motor and set it to lower than the maximum operating pressure. Otherwise, the seal may be damaged and fluid may leak. Do not touch surface of the motor while it is running. You may sustain burns. If an abnormality such as fluid leakage, lowered torque, increased noise, or lowered speed is observed, stop operation immediately and take the necessary steps to prevent secondary accidents. Do not operate the motor only with a key attached. Otherwise the key may fly out. Maintain the back pressure at no greater than 1 Ma {1 kgf/cm 2 }. Others Use the motor in compliance with the specification conditions stated in the brochure or drawings. roducts modified by the customer are not covered by the warranty and Daikin will accept no responsibility for them.
