Abstract

PURPOSE: To ensure limiting of overcurrent without delay in operation, by providing a current control means for preventing overcurrent to a motor, in which an oscillation preventing capacitor is connected between an input and an output and also a current feeding means is connected to the output.
CONSTITUTION: At the time of a stop command, a start/stop command means 89 cuts OFF a driving current to a motor on the output signal of the means 89. At the same time, a current from a current feeding means 81 is made to flow to the start/stop command means 89. Thus the charging of an oscillation preventing capacitor 80, which is connected between the input and the output of a current limiting means 82, is prevented. At the time of a start command, the current limiting means 82 passes the current from the current feeding means 81 to the current limiting means 82. The driving current to the motor is limited based on the output signal of the means 82 with the signal from a motor-driving- current detecting means 77 as an input signal.
