PURPOSE:To continue the operation of train by making a switching to remaining winding when winding B is disconnected from winding A of a speed generator. CONSTITUTION:When a priority circuit 14 responsive to higher one of the output frequency from an oscillation shaper circuit 3 or a direct-coupled shaper circuit 4 stop provision of output, a disconnection detecting circuit 7 functions to excite a TGCR relay (disconnection detecting relay for winding A of a speed generator TG) which thereby switches the contacts thereof to connect the winding B to the oscillation shaper circuit 3. |
