F0711: Fault in the execution of the SoftPLC.
Fault in the
Execution of the
SoftPLC
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 F0074 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).
(3) Manual available for download on the website: www.weg.net.
NOTE!
The user parameters (P1010 to P1059), faults (F0750 to F0799) and alarms (A0750 to A0799) related
to PID Control applications, Electronic Potentiometer (E.P.), Multispeed, Three-Wire Control (Start/
Stop), Forward and Reverse, and Special Functions of combined use are only described in Chapter
19 APPLICATIONS on page 19-1.
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:
