The following four parameters, P3-00 (Address Setting), P3-01 (Transmission Speed),
P3-02 (Communication Protocol) and P3-05 (Communication Mechanism), are essential
and must be set for the communication of the servo drive. The rest, such as P3-03
(Communication Error Disposal), P3-04 (Communication Timeout), P3-06 (Control Switch

(★) Read-only register, can only read the status. For example: parameter P0-00, P0-10
and P4-00, etc.
(▲) Setting is unable when Servo On, e.g. parameter P1-00, P1-46 and P2-33, etc.
(●) Not effective until re-power on or off the servo drive, e.g. parameter P1-01 and
P3-00.
(■) Parameters of no data retained setting, e.g. parameter P2-30 and P3-06.
