CONTROL DEVICE OF AN INDUSTRIAL ROBOT AND A REGENERATIVE POWER CONTROL DEVICE CAPABLE OF REDUCING THE WASTE OF A REGENERATIVE POWER BY RECYCLING THE REGENERATIVE POWER

摘要

PURPOSE: A control device of an industrial robot and a regenerative power control device are provided to save the energy by recycling a regenerative power as a power source using a resistor.;CONSTITUTION: A control device of an industrial robot comprises a converter(100), a driving inverter, a regenerative inverter(310) and first and second diodes(Da,Db). The converter changes the AC power source into a first DC voltage. The driving inverter changes the first DC voltage inputted through first and second input terminals(IN1,IN2) in the normal mode of the motor into the driving AC voltage and the driving AC voltage is supplied to the motor. The third and fourth input terminals(IN3,IN4) of the regenerative inverter are input a second DC voltage. The first diode is connected between the first input terminal and the third input terminal. The second diode is connected between the second input terminal and fourth input terminal.;COPYRIGHT KIPO 2012
