Fanuc P/S Alarm 87 ' BUFFER OVERFLOW '
• Flow Control or Data/Parity/Stop parameters are not configured properly
Compare the Fanuc settings and the Calmotion settings. The flow control settings need to be the same as well as the RS232 port settings.
Typical Fanuc setting for flow control would be XON/XOFF or DC codes. The Calmotion will need to be set to SW XON/XOFF
Typical Fanuc RS232 port settings are 7 data bits, Even parity and 2 stop bits. Set the Calmotion to the same.
