PURPOSE:To accurately transmit a signal from an encoder to a receiver by a simple circuit configuration. CONSTITUTION:The output signal of an encoder 200 is transmitted through a transmission cable 300 to an invertor 100 being a receiver, and the power supply voltage of the encoder 200 is supplied from the invertor 100 side through a power source cable 400. The invertor 100 is equipped with a means which supplies a voltage more than the sum of the power supply voltage of the encoder 200 and the voltage decrease of the power source cable, and the encoder 200 is equipped with a power source IC 1 which converts the voltage supplied from the invertor 100 through the power source cable 400 into own power supply voltage. |
