PURPOSE:To provide a motor controller in which current control range can be widened by switching the current resolution according to the current range. CONSTITUTION:The motor drive controller comprises a first circuit for dividing a predetermined reference voltage Vref by a divisor designated by an output signal from a control circuit 10 comprising a microprocessor and a second circuit for reducing the output signal from the first circuit with a damping rate designated by an output signal from the control circuit. Output from the second circuit is fed to a drive circuit 15 and the current resolution of the driving current of a motor 16 is determined by the first circuit while the current range is determined by the second circuit. |
