    Fuzzy most suitable acceleration and deceleration [Outline of the function] The fuzzy most suitable acceleration and deceleration function realizes acceleration and decelera- tion characteristics using the inverter capability at its maximum under fuzzy control to eliminate troublesome setting of the acceleration and deceleration time. The acceleration time is a time for acceleration at the current specified by the overload restriction constant.
