Abstract:
1. A method for mounting a plurality of servo-amplifier modules for driving motors on a multishaft servo-amplifier, each of the plurality of servo-amplifier modules includes an identical shape and an identical function to each other and has semiconductor power elements, comprising: preparing a multishaft interface substrate, that constitutes a multishaft servo-amplifier function unit for a host controller, as a base plate on which the plurality of multishaft servo-amplifier modules are mounted; mounting the multishaft servo-amplifier modules on surfaces of the multishaft interface substrate in parallel therewith; mounting the multishaft servo-amplifier modules on the both surfaces of the multishaft interface substrate to efficiently mount the plural multishaft servo-amplifier modules on the multishaft interface substrate; disposing connectors for connecting with the multishaft interface substrate on diagonally facing areas of the multishaft servo-amplifier module, disposing connectors for connecting with the multishaft servo-amplifier module on the both front and rear surfaces of the multishaft interface substrate in a zigzag arrangement, and disposing the plurality of the multishaft servo-amplifier modules alternately on the front and the rear surfaces of the multishaft interface substrate such that the connectors for connecting with the multishaft servo-amplifier module do not interfere with each other; and mounting the multishaft servo-amplifier modules on the same positions of the both surfaces of the multishaft interface substrate such that the multishaft interface substrate is sandwiched between each pair of the multishaft servo-amplifier modules, and mounting the multishaft servo-amplifier modules on the multishaft interface substrate in a side-by-side arrangement so as to efficiently mount the plural multishaft servo-amplifier modules on the multishaft interface substrate.
