A drive system for multiple motors includes a first motor, a second motor, a motor drive power supply for supplying power to the first and second motors, a first motor drive amplifier, a second motor drive amplifier, a first overcurrent detection apparatus, and a second overcurrent detection apparatus. The first overcurrent detection apparatus is connected between the motor drive power supply and the first motor drive amplifier for detecting current through the first motor drive amplifier, and comparing the current value to the first overcurrent benchmark value to output an overcurrent detection signal correspondingly. The second overcurrent detection apparatus is connected between the motor drive power supply and the second motor drive amplifier for detecting current through the second motor drive amplifier, and comparing the current value to the second overcurrent benchmark value to output an overcurrent detection signal correspondingly.
