Abstract

A vacuum pump, a vacuum pump controller, and a remote controller are provided that can reduce the workload of users and field service engineers. A vacuum pump 10 includes a turbomolecular pump 100 that exhausts gas inside a semiconductor manufacturing apparatus X, and a controller 200 that performs control on the turbomolecular pump 100 . The controller 200 includes a remote signal receiving means that receives a command signal from a remote controller 300 , which remotely controls the turbomolecular pump 100 , and changes a setting relating to an operating specification of the turbomolecular pump 100 on the basis of the command signal received by the remote signal receiving means.

Claims (18)

1 . A vacuum pump comprising:

a pump main body configured to exhaust gas inside an exhaust target apparatus; and

a controller configured to perform control on the pump main body, wherein:

the exhaust apparatus is configured such that a plurality of gases is to be introduced there, the controller includes:

a storage configured to store a plurality of operating specifications of the pump main body prepared in plural as a set of specification in which a rated rotational speed of a motor of the pump main body and a setting temperature controlled by a heater and a cooling pipe of the pump main body are associated with each other; and

a remote signal receiver configured to receive a command signal from a remote controller that remotely controls the pump main body, the command signal including an instruction for changing the plurality of operating specifications of the pump main body, and

the controller is configured to change, before a first gas of the plurality of gases is introduced, the rated rotational speed of the motor and the setting temperature to be a first operating specification from the plurality of operating specifications based on the command signal received by the remote signal receiver and the controller is configured to change, before a second gas of the plurality of gases is introduced, the rated rotational speed of the motor and the setting temperature to be a second operating specification from the plurality of operating specifications based on the command signal received by the remote signal receiver.

2 . The vacuum pump according to claim 1 , wherein the controller is configured to, when the remote signal receiver receives the command signal from the remote controller while the pump main body is in operation, change a setting of the pump main body based on the command signal without stopping the operation of the pump main body.

3 . The vacuum pump according to claim 1 , further comprising:

a specification changing device configured to change an operating specification of the plurality of operating specifications of the pump main body, wherein:

the controller is configured to change a setting relating to operation of the specification changing device based on the command signal received by the remote signal receiver.

4 . The vacuum pump according to claim 3 , wherein the specification changing device is the heater configured to heat the pump main body or the cooling pipe configured to cool the pump main body.

5 . The vacuum pump according to claim 1 , further comprising:

a control target device that is capable of changing the operating specification of the pump main body; and

a specification setting device configured to change an operating specification of the plurality of operating specifications of the control target device to change the rated rotational speed of the motor and the setting temperature to be the operating specification from the plurality of operating specifications.

6 . The vacuum pump according to claim 1 , wherein the remote controller comprises:

a remote signal transmitting means configured to transmit the command signal to the controller; and

a remote control means configured to cause the remote signal transmitting means to transmit the command signal to the controller to remotely control the pump main body.
