If you wish to use several fail-safe inputs of the inverter, this is described in the Safety
Integrated Function Manual. See also Section: Additional information on the inverter
(Page 461).
Further information on fail-safe inputs can be found in Section Fail-safe input (Page 99).

Selecting the pre-assignment for the terminal strip

The inputs and outputs of the frequency inverter and the fieldbus interface have specific
functions when set to the factory settings.
When you put the frequency inverter into operation, you can change the function of each of
its inputs and outputs and the setting of the fieldbus interface.
To make the setting process easier, the inverter has various predefined assignments
(macros).
Only the inputs and outputs whose functions change by selecting a specific assignment, are
shown on the following pages.
Procedure
To select one of the inverter's pre-assigned settings, proceed as follows:
1. Think about which of the input and output functions you are using in the application.
2. Find the I/O configuration (macro) that best suits your application.
3. Note the macro number of the corresponding default setting.
You must set this macro number when putting the frequency inverter into operation.
You have found the appropriate inverter pre-assignment.
Macro 1: Two fixed speeds
DI 4 and DI 5 = high: The inverter adds
both fixed speeds.
60
Macro 2: Two fixed speeds with safety
function
Macro 3: Four fixed speeds
Multiple DIs = high: The inverter adds
the corresponding fixed speeds.
