PURPOSE:To confirm easily and reliably that a motor of correct type is connected by calculating the resistance and the electric time constant of the stator winding of a motor and then comparing thus calculated values with those of the stator winding of various types of motors. CONSTITUTION:A motor parameter match judging section 10 compares calculation results at a motor parameter calculating section 9 with the resistance and electric time constant (their ranges are set while considering a calculation error) of the stator winding of a motor to be used, which are stored previously in a control parameter memory section 8, and decides whether a specified type of motor 4 is connected. According to the constitution, positive matching of the type of motor 4, the type of motor controller and the motor control parameters can be judged automatically at once. |
