  • Method for automatic speed loop tune-up in a machine drive
    Patent number: 4649328
    Abstract: Motor-load inertia of a drive system is determined from motor friction current and the time required to accelerate and decelerate to a predetermined speed in response to a current command. A desired response time provided by the operator is checked to determine if the response time is achievable with the motor-load inertia previously determined. The maximum achievable response time based on motor-load inertia is determined if the desired response time is not achievable. The speed loop parameters based on the achievable response time and motor-load inertia.
