In order to develop an alignment system for the Japan Linear Collider(JLC), we have constructed a test facility to study the position control system with multiple degrees of freedom for massive load. Noticeable points of the test facility are as follows. (1) Feedback fine alignment system which consists of piezoelectric actuators and laser interferometers. (2) High-speed controller using VME modules. (3) Level positioner driven by stepping motors. The controller can easily be connected with other computers by using RS-232C or Ethernet, so that their states such as positions can be monitored by another computer system. This facility achieves the alignment of multi-degrees of freedom with the accuracy of the order of submicron.
