4.2Mechanical installation
Accessibility for servicing When mounting the linear axis, the motor and the sensors, keep in mind that they may have to be accessed for servicing.
Mounting position The linear axis can be installed in any position.
If a linear axis with a mounted motor is mounted in a vertical position, the motor should be at the top. This way, the ball screw is under tension and there is no buckling stress.
4.2.1Standard tightening torques
Special tightening torques are applicable for mounting sensors and elastomer couplings; these tightening torques are listed in the appropri- ate chapters.
The following, generally applicable tightening torques apply to mounting the payload and fastening slot nuts, clamping claws, motor and contact plate with hex socket screws.
