Any misuse of password may lead to severe safety
problems.

NOTICE

No password is required to access the commissioning
parameters of the safety option. The password is
required when the parameters must be downloaded to
the option via 

Write to Drive

.

The password 

must

 be of 8 characters and is case-

sensitive. Alphanumeric characters and symbols are valid
for password.

The safety option checks the parameter password entered.
Use the menu item 

Change Password

 to change the safety

option parameter password. Change the safety option
password if there is any indication of manipulation.

6.1.3.1 Password Forgotten

NOTICE

Resetting the password resets all option parameters to
factory default. 

Forgot the safety option parameter password?

6.2  Reset and Status over Fieldbus

6.2.1 Reset of Safety Option and Pending

Safe Function

There are 2 different methods of performing a reset of the
safety option and pending safe function. The configuration
of 

42-31 Reset Source

 is decisive for which method to use. 

If 

42-31 Reset Source

 is set to 

[0] Drive Reset

, a reset

according to the selected control word profile is required.

NOTICE

The frequency converter specific alarms are also reset.

If 

42-31 Reset Source

 is set to 

[1] Drive Safe Reset

[3] Safe

 must be configured in 

8-14 Configurable

.

NOTICE

The frequency converter specific alarms are not reset
and the control word profile is overwritten.

6.2.2 Retrieving Safety Option Status

A subset of the safety option status can be retrieved as
part of the status word. It's behaviour changes based on
