PROBLEM TO BE SOLVED: To provide a motor controller which is small in loss, by reducing the loss during waiting of a motor. SOLUTION: This motor controller has a gate block condition setter 9 which sets the conditions of gate block to stop the supply of control signal to a semiconductor element for power constituting a power converter 8; an internal condition setter 10 which sets the internal operation conditions concerned with the operation of the device; a receiving circuit 11 which receives the waiting command W1 from a master device 7; an operation starting circuit 12 which performs the logical product operation between the operation start command S from the master device 7 and the internal operation conditions IC set with the internal condition setter 10, and sends an operation start signal SS when it fulfills the AND condition; a gate block circuit 13 which performs the AND operation between the waiting command W1 from the receiving circuit 11 and the gate block condition GC set with the gate block condition setter 9, and sends a gate block signal GS when it fulfills the AND condition; and an element control circuit 14 which supplies each of semiconductor elements for power with control signals, based on the output signals from the operation starting circuit 12 and the gate block circuit 13. |
