PURPOSE:To reduce acceleration/deceleration delay at the time of accelerating a motor and to suppress a variation in the speed of the motor at the time of abrupt load change. CONSTITUTION:In addition to a conventional speed control amplifier, a speed pattern generator for applying an ideal target speed of a motor corresponding to a speed reference, and a compensating amplifier for comparing the ideal speed of the generator with the speed of the motor and compensating the output of the amplifier according to its deviation, are provided. |
