| description | A motor control system for a hoist drive having an electric motor (2) operationally connected to a hoisting member (4) for hoisting a load (6), the motor control system being adapted to generate a final angular frequency reference (É * s ) for control of the electric motor (2), the motor control system comprising a power limiter means (8) adapted to generate a correction term (É s,cor ) for angular frequency reference. The power limiter means (8) comprises an integrating controller means (10), the power limiter means (8) being adapted to generate the correction term (É s,cor ) for angular frequency reference using output signal I P of the integrating controller means (10), initial data of the integrating controller means (10) including information relating to actual value of the power of the electric motor (2) and a power related limit value of the electric motor (2). |
