Abstract
PURPOSE: To make the interlocking operation possible without time delay by directly interlocking one AC switch by a command signal by the action of a rotary command switch, and thereafter turning on the other AC switch.
CONSTITUTION: When a forward rotation command switch SF is compressed, the first delay capacitor C1 is charged via the first charging resistor R1, and the photoelectric potential is applied to the second reversing circuit IR and the first AND circuit AF as the first command. When the charged potential of a capacitor C1 reaches the working level of the second reversing circuit IR, the output signal of the reversing circuit is reversed, the second AND circuit AR is interlocked, and the second AC switches UR and VR are kept "off". When the charged potential of the capacitor C1 reaches the working level of the circuit AF, the output signal from the circuit AF is reversed, the first AC switches UF and VF are turned on by the signal from the first gate driving circuit GF, and three-phase motor 2 is rotated to the forward direction.
