Abstract

PURPOSE: To cooperate the speeds of a plurality of AC motors by using the frequency signal obtained by a special inverter as the frequency command signal of other inverter.
CONSTITUTION: If the first inverter 37-1 operates a stall preventing function when the first AC motor 6-1 is driven by the first inverter 37-1, a frequency signal is varied. The frequency signal is produced from a signal terminal 36, and input to the frequency command signal terminal 33 of the second∼n-th inverters 37-2∼37-n. Thus, the first inverter 37-1 and the second∼n-th inverters 37-2∼37-n are controlled by the same frequency signal.
