Z60 Fieldbus communication error n1 n2 n3 n4
Details
A communication error has occurred on the Fieldbus communication with HN571/HN573/HN575.
[n1 :Shows state of the master channel (shown in hexadecimal number)]
00 :Offline In initializing
40 :Stop Cutting I/O communication
80 :Clear Resetting output data of each slave by sending 0 data.
C0 :In operation I/O In I/O communication
[n2 :Shows error state (shown in hexadecimal number)]
bit0 :Control error Parameter error
bit1 :Auto clear error Communication with all the slave channels was cut because a communication
with one slave channel had an error.
bit2 :Non exchange error Slave channel with communication error is found.
bit3 :Fatal error The communication cannot be continued because severe network failure exists.
bit4 :Event error Short-circuit was found on the network.
bit5 :Not ready CNC communication is not ready.
bit6 :Time out error Time out was detected in communication with each channel.
bit7 :Not used
[n3 :Shows error No. (shown in hexadecimal number)]
- Error in master channel (when remote address with an error is FF (hexadecimal number))
0 :No error Operating normally
32 :No USR_INT Damage in HN571. Replace HN571.
33 :No global data field
34 :No FDL-task
35 :No PLC-task
37 :Master parameter incorrect
39 :Slave parameter incorrect
3C :Data offset exceeding allowable set value received. Check the configuration setting.
3D :Slave data send range overlap
3E :Slave data receive range overlap
3F :Not set data hand shake Damage in HN571. Replace HN571.
40 :RAM range exceeded
41 :Slave parameter data set illegal
CA :No segment
D4 :Data base read illegal Download the configuration data again.
D5 :Operating system illegal Damage in HN571. Replace HN571.
DC :Watch dog error
DD :Hand shake mode No data communication by 0
DE :Master auto clear mode When setting auto clear mode, the auto clear mode was performed
because one slave was not able to connect in run time.
- Error in slave channel (when remote address with an error is other than FF (hexadecimal number))
Check the configuration of slave channel in which error has occurred. Check if there is any short-
circuit in wire to bus.
2 :Station overflow reported
3 :Station stopped responding to master command
9 :No slave required responding data
11 :No station respond
12 :No master to logical token ring
15 :Illegal parameter requested
[n4 : Shows slave No. where communication error has occurred. (shown in hexadecimal number)]
'FF' means an error in master channel.

Remedy
- Obtain a decryption code from the machine tool builder and input it in the NC, then turn the power
ON again.
Z65 Valid term has been expired
Details
The valid term has been expired with no decryption code input.
Remedy
- Obtain a decryption code from the machine tool builder and input it in the NC, then turn the power
