ABSTRACT:
Method and system are provided for controllably driving a rotary drive of a rotary index table assembly utilizing a PLC which receives various sensor signals including a feedback signal from a resolver to generate a reference central signal which, in turn, is used by a positioning drive including an electric servomotor to drive the rotary drive. The positioning drive includes a servoamplifier and a microprocessor for generating commands for controlling the servoamplifier in response to the reference central signal. The PLC also controls a hydraulic control unit which controls the axial position of the index table relative to a base of the assembly.
