PURPOSE:To readily and accurately alter the setting speed of a motor by arbitrarily setting the reference setting speed of the motor sequentially generated upon lapse of a time and the period via sole variable resistors, respectively. CONSTITUTION:The set voltages n1 and 0V of a variable resistor RH1 are added by an adder 4, which outputs a voltage n1, the output of the first lamp function generator 1 becomes -n1 after the set time t1 by a variable resistor RH2, and the outputs of adders 7, 9 becomes -n1 upon ON of switches S2, S3. When the switch S2 is opened, the output of the lamp function generator 2 becomes -(n2-n1) after the set time t2 by a variable resistor RH4, and the outputs of the adders 7, 9 become -n2. When the switch S3 is opened, the output of a lamp function generator 3 becomes -(n3-n2) after the set time t3 by a variable resistor RH6, and the output of the adder 9 becomes -n3. |
