PROBLEM TO BE SOLVED: To provide a load drive control device capable of detecting a disconnection of a load.SOLUTION: The load drive control device includes a load disconnection detection switch 26, which becomes an on-state by being applied with a driving signal from a power supply through a load 3 when a load-stop command is given in a state in which the load is connected, and becomes an off-state when a driving signal is not applied from the power supply through the load due to a disconnection of the load. By measuring a voltage across the switch when a load-stop command is generated, whether the load is disconnected or not is detected. The load drive control device also includes stop command at load driving generation means 24 for generating a load-stop command at a time at which an interruption of driving a load is allowed even when the load is being driven, so as to detecting a disconnection of a load while the load is being driven. |
