21[Before Use]Before UseCable: Stress relieving(1) Don’t apply stress to the cable lead-out port and connections by bending and self-weight.(2) Particularly in the case of application in which the servo motor must be movable, fix the accessory cable of themotor and house the extension junction cable, which is connected to the terminal end of the said cable, in thecable bearer to thereby minimize stress acting on the cable by bending.(3) Make the cable bending radius as large as possible. (Minimum bending radius: to be 20 mm and over.)Permissible Shaft Load(1) Do mechanical design so both of radial load and thrust load being applied to the motor shaft during installationand running are maintained within the permissible value specified for each model.(2) In using the rigid coupling, take good care of mounting. (Over-bending load on it, if any, would cause damage/wear of the shaft and shorter life of the bearings.)(3) Use the flexible coupling of possibly high stiffness to control radial load arising from minor center deviation at thepermissible value or less.(4) For information on allowable load of an output shaft of each type, refer to Allowable Load of Output Shafts onPage 196 of Reference.Installation Notes(1) When connecting /disconnecting the coupling to/from the motor shaft end, don’t applydirect impact to the shaft by hammering, etc. (Failure to observe this instruction wouldcause damage of the encoder mounted on the counter-load side shaft end.)(2) Do perfect centering. (Imperfect centering would result in vibration, which would causedamage of the bearings.)MotorBuy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com
