5 ERRORS RELATED TO THE FIELDBUS COMMUNICATION
Fault
Description of the Actuation
Possible Causes and Solutions
E30
Communication
board inactive
(P085 = 1)
When during the starting process of the
communication board (after power on or
reset), the drive cannot execute with success
the routines that enable the board.
During the drive operation, when the drive
cannot access correctly the data of the
communication board.
In general, the fault message E30 occurs due the problems during the
data exchange between the control board of the Soft-Starter SSW-06
and the communication board.
■ Check if the communication board model (Profibus DP or DeviceNet)
matches with the programmed one in P309.
■
Check the installation of the communication board, looking if there
are bent pins, or if there is bad connection to the bus that connects
the communication board to the connector XC12 of the Soft-Starter
SSW-06 control board.
■
Check the condition of these connectors by noting if there is
oxidation or any foreign material that can impair the connection.
Please note that after the fault E30 has been detected, the drive can
only be operated again by the communication board afte
r the drive is
reset.
E29
Communication
Fieldbus
inactive
(P085 = 2)
The communication with the network master
is not possible after the communication
board has been programmed at P309 The
drive is offline and indicates the fault E29 on
the HMI.
This fault message is displayed when the communication board is
unable to communicate with the network master. This fault can occur
due to two reasons: fault in the master configuration ou due to network
connection.
Problems with the network connection:
■ Check if the cable passage has been carried out properly and if the
drives and the cable shields have been grounded correctly.
■
Check if there are no bad contact problems, contact oxidation or
short-circuit between the network signals. Check also if the signal
transmission cables are not broken or reversed.
■ Check if the two segments of the termination resistors are disposed
correctly.
■ Check if the used communication baud rate is not too high and if the
cable length is not out of allowed range. In ge
neral the network
becomes more susceptible to problems, the higher the used
communication baud rate.
Problems with the master configuration:
■
Check if the number of I/O words that were programmed in the
master is the same as configured in the slave (se
e parameter
description P309 - item 3.2
). The indication LEDs on the
communication board can give information about this condition (see
Table 3).
■ Check if the address programmed for the slave is the same address
that has been configured for the master.
■ Check if the GSD or EDS files of the communication board Anybus-S
were recorded correctly and if they were used by the network
configuration tool.
■ For the network DeviceNet, the master must be in running status. If it
is Idle status, the drive will display the fault E29.
■
For the Profibus network there is the function for detecting the
master in Stop. It is necessary to observe if this function is active (by
means of
parameter P310), if the master is in Stop and if the bit
corresponding to this function in the command word is active.
■ Specific configurations of a determined equipment can also influence
the communication. Is this case, a good knowledge about the master
operation on the network is required.
E29
Intermittent
The drive is unable to communicate to the
master, and eventually the fault E29 can be
displayed, informing that the communication
board is offline.
If the communication is online, this means that the master has been
configured correctly and that the communication to the slave is
possible. In this case, eventual errors may be caused due to installation
problems or electromagnetic interference.
■ Check if the cable passage has been carried out properly and if the
drives and the cable shields have been grounded properly.
■
Check if there are no bad contact problems, contact oxidation or
short-circuit between the network signals.
■ Check if the two segments of the termination resistors are disposed
correctly.
■ Check if the used communication baud rate is not too high and if the
cable length is not out of allowed range. In general the network
becomes more susceptible to problems, the higher the used
communication baud rate.
