Abstract

PURPOSE:To perform a stable stall compensation control by quickly detecting a stall generated either in power running or in regeneration. CONSTITUTION:When a stall is detected in acceleration of an AC motor 6, a power running state is retained in a holding circuit 31 by rise of a stall detection signal, a polarity switching circuit 32 operates in the direction of lowering a frequency standard, and a contact 34 is closed. Therefore, the frequency standard rapidly lowers by the integral action of a stall compensation circuit 33. Then, an inverter action becomes a regeneration state. However, the polarity of a stall compensation signal is retained by the holding circuit 31 and the lowering of the frequency standard is continued. When an error signal reaches the level of a set point, the integral action of said stall compensation circuit 33 stops, the contact 34 is opened, and acceleration is conducted at a usual acceleration rate thereafter.
