■Baud rate (Un\G24)
Set the baud rate for communications. The current value for the baud rate can be checked with 'Baud rate display' (Un\G37).
( Page 161 Baud rate display (Un\G37))
• 10: 10kbps
• 20: 20kbps
• 50: 50kbps
• 100: 100kbps
• 125: 125kbps
• 250: 250kbps
• 500: 500kbps
• 800: 800kbps
• 1000: 1000kbps
If a value other than above is set, 'Error status' (Un\G29.6) turns on. ( Page 139 Troubleshooting Using the Buffer
Memory)
• Send buffer overflow may occur if data exchange is performed quickly when the baud rate is low or the bus
load is high. ( Page 139 Troubleshooting Using the Buffer Memory)
• To change this setting when the 11-bit CAN-ID Layer 2 message mode or 29-bit CAN-ID Layer 2 message
mode is active, bring the RJ71CN91 into the offline mode, change the setting, and then bring the
RJ71CN91 into the online mode. When the RJ71CN91 transitions to the online mode, the setting is
enabled.
To change this setting when the CANopen 405 mode is active, save the data in the buffer memory into the flash ROM, and
*1
then restart the RJ71CN91.
