9. This also can destroy mechanical end of travel switches and the lead screw nut or belt amp pulley assembly Therefore it is not a good practice to use any positioning table s end plates as a mechanical hard stop Another cause of coupling failure can occur during the tuning of a servo system that is attached to the position ing table When servo gains are first adjusted violent oscillations can occur which can fatigue or damage a coupling Care should be taken to limit these wild oscillations by either tuning the servo system before coupling the motor to the table or by limiting the current in the servo drive during the tuning process Motor Adapter Brackets Another important area of coupling concern is in cases where a non LINTECH mo tor adapter bracket is being installed by the user to a positioning table In some cases the added bracket thickness along with a potentially short motor shaft extension can cause the LINTECH supplied coupling to be too short to clamp onto the motor shaft If such a situation arises a different coupling with a longer length may be required See page 17 for a list of standard LINTECH couplings Custom couplings will require factory contact to determine torque capacity Cou pling Maximum Torque values shown on the next page define the input torque at which the coupling can immediately fail It is good practice to select a coupling which has at least 2x two times the safety margin above the PEAK cou
