Timeout error

Details
Communication ended with timeout.
(CNC has a 248-byte receive buffer. The time during which CNC receives 248 bytes exceeds the 'TIME-OUT'
value set in the I/O device parameter.
Remedy
Set a greater timeout value in the input/output device parameter.
Check the software in HOST and make sure that the HOST transmits data in response to DC1(data re-
quest) from CNC.
Set '#9614 START CODE' to '0'.
L01

Host ER signal OFF

Details
ER signal in HOST (or DR signal in CNC) is not turned ON.
Remedy
Check for any disconnected cable.
Check for any broke wire.
Make sure that the HOST power is turned ON.
L01

Parity H error

Details
Communication ended with parity H.
Remedy
Check the software in HOST and make sure that the data to be transmitted to CNC is ISO code.
L01

Parity V error

Details
Communication ended with parity V.
Remedy
Correct the data to transmit to CNC.
L01 Overrun error
Details
CNC received 10 bytes or more data from HOST in spite of DC3 (request to stop data transfer) transmission
from CNC to the HOST, which terminated the communication.
CNC received 10 bytes or more data from HOST during the data transmission from CNC to the HOST.
Remedy
Check the software in HOST and make sure that the HOST stops transmitting data within 10 bytes after
receiving DC3.
Correct the software in HOST not to transmit data such as a command or header to CNC during receiving
a machining program.
