Timeout
F238: (2) It indicates that the inverter received a
Profibus DP command from the Profibus DP network
Interface in Clear master to enter the clear mode.

Notes:
(1) Very long motor cables, with more than 100 m (328.08 ft), presents a high parasitic capacitance to the ground. The
circulation of a leakage current through this capacitance may cause the activation of the ground fault circuit, and
consequently an F074 trip immediately after the inverter enabling.
POSSIBLE SOLUTION:
To reduce the switching frequency (P0297).
(2) With the Profibus DP module connected into the slot 3 (XC43).
ATTENTION!
A bad contact in the HMI cable, or electric noise in the installation, can cause a failure in the
communication between the HMI and the control board. In such case, the operation through the HMI
becomes impossible and the HMI indicates the following message on the display:
26 | CFW700
Description Possible Causes
Verify the network master status, making sure it is in
the execution mode (Run).
The fault indication will occur if P0313 = 5.
Refer to the Profibus DP communication manual for
more information.
Verify whether the network master is correctly
configured and operating normally.
Verify the network installation in a general manner -
cable routing, grounding.
The fault indication will occur if P0313 = 5.
Refer to the Profibus DP communication manual for
more information.
Verify whether the Profibus DP module is correctly
fit into the slot 3.
The fault indication will occur if P0313 = 5.
Refer to the Profibus DP communication manual for
more information.
