Fault/Alarm
A700: Alarm or fault related to the HMI disconnection.

Disconnected HMI
F701:

Disconnected HMI
A702: Alarm indicating that the General Enable

Disabled Inverter command is not active.
A704: Two movements have been enabled.

SoftPLC
Models at which they may occur:
(1) With a Profibus DP module connected into the slot 3 (XC43).
(2) All the frame size G models.
(3) With an IOE-01 (02 or 03) module connected into the slot 1 (XC41).
(4) All the models with a SoftPLC applicative.
(5) Very long motor cables (longer than 100 meters) present a high parasite capacitance against the ground.
The circulation of parasite currents through those capacitances may cause the ground fault circuit activation
and thus disabling the inverter with F074, immediately after the inverter enabling.
NOTE!
The range from P0750 to P0799 is destined to the SoftPLC applicative user faults and alarms.
(6) CFW110370T4, CFW110477T4, and all the frame size G models.

Description
Troubleshooting and Maintenance
Possible Causes
RTC function block has been activated in the SoftPLC applicative
and the HMI is disconnected from the inverter.
The SoftPLC Run/Stop command is equal to Run or a movement
block has been enable while the inverter is general disabled.
It occurs when two or more movement blocks are enabled
simultaneously.
It occurs when a movement block has been enabled and the
speed reference has not been configured for SoftPLC (check
P0221 and P0222).
