Vacuum pump, vacuum pump controller, and remote controller

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.
