NOTE: The

Hardware settings submenu

is protected with a password (see chapter Password (S6.5.1)).

Store the password in a safe place!

In the

Hardware settings submenu

(S6.7) under the

System menu

you can further control some functions

of the hardware in your frequency converter. The functions available in this menu are

Internal brake

resistor connection, Fan control, HMI acknowledge timeout and HMI retry.

Internal brake resistor connection (P6.7.1)

With this function you can tell the frequency converter, whether the internal brake resistor is connected or
not. If you have ordered the frequency converter with an internal brake resistor, the default value of this
parameter is

Connected.

However, if it is necessary to increase braking capacity by installing an external

brake resistor, or if the internal brake resistor is disconnected for another reason, it is advisable to change
the value of this function to

Not conn.

in order to avoid unnecessary fault trips.

Enter the edit mode by pushing the

Menu button right

. Use the

Browser buttons

brake resistor status. Accept the change with the
