Communication device is a communication device to which a plurality of slaves are daisy-chained and which communicates with the plurality of slaves. Communication device includes processor. Processor executes setting processing. In the setting processing, an update cycle of a specific slave that is a slave having a shortest data update cycle among the plurality of slaves is set to a reference cycle, and an update cycle of another slave different from specific slave among the plurality of slaves is set to an integral multiple of the reference cycle.

Communication device, communication system, and communication control method

A linear motor system includes: a stator including first to tenth coils; a mover including a permanent magnet; a switcher that switches one or more power supply target coils; and first to tenth amplifiers provided in one-to-one correspondence with first to tenth coils. One or more amplifiers that serve as new one or more power supply target amplifiers immediately after the switching calculate &#x394;&#x3b8; (t), which is a position deviation at time t=t, based on &#x394;&#x3b8; (t)=&#x394;&#x3b8; (t&#x2212;td)+A&#x2212;B, where A is a difference between an instructed position at time t=tand an instructed position at time t=t&#x2212;td, and B is a difference between an actual position at time t=tand an actual position at time t=t&#x2212;td, and supply power to the power supply target coils by the position deviation &#x394;&#x3b8; (t).
