Provided is an installation mode determination device capable of determining an installation mode of an automatic machine. The installation mode determination device acquires estimated torque that is required for maintaining a stationary state in which a position of an automatic machine that includes at least one axis that is driven by a servomotor is retained in a set installation mode among a plurality of installation modes applicable to the automatic machine, calculates actual torque that is actually provided by the servomotor for maintaining the stationary state, and determines whether the set installation mode and an actual installation mode of the automatic machine are different or not, based on a difference between the estimated torque corresponding to the set installation mode and the actual torque.
