8. COMMUNICATION FUNCTIONS
(3) RS-422/RS-232C serial interface selection
Select the RS-422 or RS-232C communication standard. RS-422 and RS-232C cannot be used together.
RS-422/RS-232C communication standard selection
0: RS-422 used
1: RS-232C used
Parameter No. 16
(4) Communication delay time
Set the time from when the servo amplifier (slave station) receives communication data to when it
sends back data. Set "0" to send back data in less than 400 s or "1" to send back data in 400 s or more.
Communication delay time
0: Invalid, reply sent in less than 400 s
1: Valid, reply sent in 400 s or more
Parameter No. 16
(5) Serial communication time-out
No communication for a given period of time between the master and slave stations may be judged as
a communication cable or master station fault to stop the servo motor.
Setting Description
0 No time-out check
1 to 60
Time-out check period setting
Check period setting (S)
8.3 Protocol
POINT
Whether station number setting will be made or not must be selected if
the RS-232C communication function is used.
Since up to 32 axes may be connected to the bus, add a station number or group to the command, data
No., etc. to determine the destination servo amplifier of data communication. Set the station number to
each servo amplifier using the parameter and set the group to each station using the communication
command. Transmission data is valid for the servo amplifier of the specified station number or group.
When " * " is set as the station number added to the transmission data, the transmission data is made
valid for all servo amplifiers connected. However, when return data is required from the servo amplifier
in response to the transmission data, set "0" to the station number of the servo amplifier which must
provide the return data.
