Provided is a wiring error detection device capable of detecting errors in the wiring to a motor controlled by a plurality of amplifiers. A wiring error detection device for detecting errors in the wiring to a motor controlled by a plurality of amplifiers, said wiring error detection device being provided with: a control amplifier selection unit that, in order to control the motor using some of the plurality of amplifiers, determines two or more selection patterns by selecting and combining amplifiers for the control; a command generation unit that generates, for each selection pattern determined by the control amplifier selection unit, a command for causing the motor to perform a predetermined operation; a servo control unit that calculates torque command values for controlling the motor, on the basis of the selection patterns and a command from the command generation unit; and a wiring error checking unit that compares the torque command values or the current feedback values of the motor that correspond to the two or more selection patterns with each other to determine the presence or absence of a wiring error in the system formed by the amplifiers and the motor.
