The WEG CFW700 unit may trip a 30mA RCD due to a ground fault. According to the context, fault F074 indicates a ground fault caused by a short-circuit to ground in one or more output phases. This type of fault can cause leakage currents that exceed the 30mA threshold of an RCD, leading it to trip.

This signal is called the process variable, and can be visualized at the parameter P1012. A setpoint is programmed in the CFW700 via keypad (P1025), through an analog input (such as a 0-10 V or 4-20 mA signal) or via communication network.
Page 192 The digital outputs (DO1 to DO5) can be programmed to trigger comparison logics with the process variable (PV). In order to do that, it is necessary to set one of the DO’s parameters (P0275 to P0279) to 34 = Function 1 of the Application (VP>VPx) or 35 = Function 2 of the Application (VP<VPy). 19-2 | CFW700...

19.3 ELECTRONIC POTENTIOMETER APPLICATION (EP) 19.3.1 Description and Definitions The CFW700 has the ELECTRONIC POTENTIOMETER (EP) function that allows the speed reference to be adjusted via two digital inputs, one for accelerating and another for decelerating the motor. With the inverter enabled and the DIx digital input set to “Function 1 of the Application (Accelerate)” activated, the motor is accelerated according to the programmed acceleration ramp up to the maximum speed.
Page 207: Operation
1. Selecting the application: When the electronic potentiometer application is enabled, setting P1003 = 2, the default applicative is loaded in the SoftPLC function, making it available for use in the CFW700. 2. Setting the digital input for the Accelerate command: It is necessary to define which digital input will do the Accelerate command of the electronic potentiometer application.
Page 208: Parameters
SoftPLC in parameter P1001 to 1 (run application). Any value other than 3 or 4 indicates that the applicative cannot go into operation. For more details, refer to the CFW700 SoftPLC manual.
