Abstract
In a mounting apparatus for electronic components, a command from a host computer is transmitted to a linear motor M via a motion controller and a servo amplifier to thereby drive a mounting head Hor a mounting head H. To prevent collision between the two mounting heads H, H, position information from a linear encoder E is fed back to not only the servo amplifier, but also the motion controller. Once determining that the two mounting heads H, Hcollide, the motion controller applies brake to the mounting heads H, Hto avoid collision therebetween, regardless of the command from the host computer.
