RS-485/RS-232 Communication parameter setting
PD-00 Setting of the branch number, PD-01 Communication transmission rate and PD-02 Protocol are the
parameters must be set and confirmed before a servo drive is connected to the communication network. Rest
of the settings are optional, including PD-03 Handling of the communication error, PD-04 Setting for the
communication timeout, PD-06 Control switch for the source of the input contact (DI), PD-07 Time for the
delay of the communication response and PD-08 Monitoring Mode. Refer to Chapter 7 in the manual for
details.

When RS-232/RS-485 is used for communication, only one branch number may be set per servo drive.
If one branch number is set for multiple drives in the communication network, the communication would not
work properly.
The station number implies the address of the drive in the communication network. It is also applicable to
RS-232/485.
