PURPOSE:To improve a follow-up characteristic at an accelerating time, and to reduce vibration at a ceasing time, by switching the gains of a speed feedback and a position feedback corresponding to a control system. CONSTITUTION:A servomotor control device is constituted of a system controller 1 which generates a various kinds of data, and a control mode switching signal, a deviation counter 2, F/V conveter 8 and 14, and a control mode switching analog switch 11, etc. At such a time, the titled device is constituted so that the first and the second position deviation amplifiers 12 and 15 are used instead of a position deviation amplifier, and the first and the second position amplifiers 13 and 16, instead of a speed deviation amplifier, and the feedback loop gains of a speed and a position can be switched. In this way, a speed control to a targeted position is performed by setting the analog switch 11 to B side and a position control is performed by setting it to A side after arriving at the targeted position. |
