box or a fan installed on the ceiling.
(3) When installing the control box in a place where there are much toxic gas, dirt and dust, conduct an air
purge (force clean air into the control box from outside to make the internal pressure higher than the external pressure) to prevent such materials from entering the control box.

2.4 Cable stress

(1) The way of clamping the cable must be f ully examined so that flexin g stress and cable's own we ight
stress are not applied to the cable connection.
(2) For use in any application where the servo motor moves, fix the cables (encoder, power supply, brake)
supplied with the servo motor, and flex the optional encoder cable or the power supply and brake wiring cables. Use the optional encoder cable within the flexing life range. Use the power supply and brake wiring cables wit hin the fl exin g li fe of the ca b les .
(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 th e servo motor w ill move, the fle xing radius should be made as
large as possible. Refer t o sect ion 1 1. 4 for t he flexi ng li fe.
