Abstract

PURPOSE:To shorten coasting distance, by judging the directions of an overtravel signal and a torque command then operating a dynamic brake(DB) circuit against operation toward overtravel side and turning a main power element OFF. CONSTITUTION:An A.C. servo controller comprises a speed amplifier 1, a torque limiting circuit 2, a current command circuit 3, a current amplifier 4, a power PWM circuit 5, a magnetic pole detector 7 and a speed detector 8 fixed to an SM motor 6. Directions of an overtravel signal and a torque command are judged through a logic circuit 9, then a DB circuit 10 is operated against operation toward over travel side and a main circuit power element in the power PWM circuit 5 is turned OFF.
