REMARKS
 The command source of communication is as set in Pr. 551 .
 The
Pr. 338
and
Pr. 339
settings can be changed while the drive unit is running when
Pr. 77
= "2". Note that the setting change is
reflected after the drive unit has stopped. Until the drive unit has stopped, communication operation command source and
communication speed command source before the setting change are valid.
