Typical Control Connections - WEG CFW-11 Series User Manual

5. Relays, contactors, solenoids or coils of electromechanical brakes installed close to the inverter may
occasionally generate interferences in the control circuitry. To eliminate this effect, RC suppressors (with AC
power supply) or freewheel diodes (with DC power supply) must be connected in parallel to the coils of these
devices.

3.2.6 Typical Control Connections

Control connection 1 - Run/Stop function controlled from the keypad (Local Mode).
With this control connection, it is possible to run the inverter in local mode with the factory default settings.
This operation mode is recommended for first-time users, since no additional control connections are required.
For the start-up in this operation mode, please follow instructions listed in
AND START-UP on page
Control connection 2 - 2-Wire Run/Stop function (Remote Mode).
This wiring example is valid only for the default factory settings and if the inverter is set to remote mode.
With the factory default settings, the selection of the operation mode (local/remote) is performed through the HMI
key LOC (local mode is default). Set P0220 = 3 to change the default setting of HMI key
