Abstract
A DSP of a servo control circuit obtains a movement value of a servomotor for each axis for each position-speed feedback processing cycle in accordance with a move command value for each axis delivered from a main processor with every distribution cycle, and also obtains a position correction value in accordance with pressure information detected by a sensor. The DSP of the servo control circuit carries out position-speed feedback processing with the use of a move command value which is obtained by correcting the movement value with the obtained position correction value, and drives the servomotor.
