<P>PROBLEM TO BE SOLVED: To provide a speed command setting method suitable for a motor variably driven by a motor drive such as an inverter. <P>SOLUTION: A circuit is constituted of an operation device 1, an input circuit 2, a multiplier 6, an adder 7, a limiter 8, an upper-limit setter 9, a lower-limit setter 10, an X<SB>1</SB>setter 21, a Y<SB>1</SB>setter 22, a X<SB>2</SB>setter 23, a Y<SB>2</SB>setter 24, and an operator 25. Two coordinates positions on a relational characteristic line between an input command-a speed command are taken as [X<SB>1</SB>, Y<SB>1</SB>] and [X<SB>2</SB>, Y<SB>2</SB>], and they are set to the circuit, thus embodying a relationship between a given input command value and speed command value. <P>COPYRIGHT: (C)2004,JPO |
