12.3.6 Faults and Analysis
LED display analysis
Run
This light indicates if PROFIBUS adapter is running normally. If PROFIBUS
adapter is correctly connected to the frequency converter, and related param‐
eter configuration for the frequency converter is correct, this light is always on
after power is switched on. If this light is flashing, please switch off the power
supply first, and then check if PROFIBUS adapter is correctly connected with
the frequency converter, if frequency converter parameters are correctly con‐
figured, and if PROFIBUS adapter power connection is reliable. After that,
switch power on for PROFIBUS adapter. If this problem still exists, please
contact your dealer.
Line
This light indicates the status of communication between the PROFIBUS
adapter and the frequency converter. It indicates normal communication if
this light is always on. If this light is off, it indicates disconnection between the
adapter and the frequency converter. Then, please check hardware connec‐
tion between PROFIBUS adapter and frequency converter. If this light is
flashing, it indicates abnormal connection between the adapter and the fre‐
quency converter. Then, please check hardware connection between the
PROFIBUS adapter and the frequency converter.
Net
This light indicates the status of communication between the PROFIBUS
adapter and PROFIBUS master. If this light is always flashing, it indicates
normal communication. If this light is off, please check hardware wiring be‐
tween the PROFIBUS adapter and master, and check if the master configura‐
tion is correct.
Diagnosis information of master
From diagnosis of the adapter by master, 6-byte diagnosis information is ob‐
tained. Detailed meanings for each byte are as below:
● First byte (Station_Status_1)
0
Diag.Station_Non_Existent (set by master, reset by slave)
1: slave does not exist
1
Diag.Station_Non_Ready (set by slave)
1: slave is not ready for data exchange
2
Diag.Cfg_Fault (set by slave)
1: Adapter data received does not match with originally configured data
3
Diag.Ext_Diag (set by slave)
1: diagnosis entrance is at undetermined diagnosis area of the slave
4
Diag.Not-Supported (set by slave)
1: service not supported by slave
5
Diag.Invalid_Slave_Response (set by master, reset by slave)
1: invalid response of slave
6
Diag.Prm_Fault (set by slave )
1: invalid parameter or parameter value
7
Diag.Master_Lock (set by master, reset by slave)
1: parameters of slave are set by other masters
