2. INSTALLATION
2.3 Keep out foreign materials
(1) When installing the unit in a control box, prevent drill chips and wire fragments from entering the
servo amplifier.
(2) Prevent oil, water, metallic dust, etc. from entering the servo amplifier through openings in the control
box or a fan installed on the ceiling.
(3) When installing the control box in a place where there are toxic gas, dirt and dust, provide positive
pressure in the control box by forcing in clean air to prevent such materials from entering the control
box.
2.4 Cable stress
(1) The way of clamping the cable must be fully examined so that flexing stress and cable's own weight
stress are not applied to the cable connection.
(2) In any application where the servo motor moves, the cables should be free from excessive stress. For
use in any application where the servo motor moves, run the cables so that their flexing portions fall
within the optional motor cable range. Fix the motor cable and power lead of the servo motor.
(3) Avoid any probability that the cable sheath might be cut by sharp chips, rubbed by a machine corner or
stamped by workers or vehicles.
(4) For installation on a machine where the servo motor will move, the flexing radius should be made as
large as possible. Refer to section 11.4 for the flexing life.
