Abstract
A vector control inverter comprises at least one of a set of a torque estimating unit that estimates an output torque of a motor from excitation current and torque current and a pulse transmitting unit that outputs a torque estimation value estimated by the torque estimating unit as positive-negative identifiable pulse stream signals, and a set of a pulse array input unit that receives pulse stream signals input from outside as positive and negative values and a torque instruction converting unit that converts the received pulse stream signals into a torque instruction to be transferred to the motor as a torque.
