Rectifier/Regenerating Unit    Operating Instructions 
4.3.9  Function selection   (P052) 
Function selection is activated via parameter P052 and permits various special functions during the start-up 
phase. 
 
Access stage 2 (
P051 = 2) must be enabled and the rectifier/regenerating unit may only be in the "Run" (R) 
status. Apart from this, P053 must be set for parameter enable (e.g. P053=6). 
 
The following functions are available: 
  - Return from function selection  (P052 = 0) 
  - Generate factory setting  (P052 = 1) 
  - Initialization (MLFB setting)  (P052 = 2) 
  - Download  (P052 = 3) 
  - Hardware configuration  (P052 = 4) 
  - Drive setting  (P052 = 5) 
  - Forming  (P052 = 20) 
  - Circuit identification  (P052 = 21) 
  - Display modified parameters  (P052 = 22) 
 
The "Generate factory setting", "Forming", and "Circuit identification" functions are automatically reset on 
completion, i.e. P052 = 0 ("Return"). 
The other functions must be manually reset! 
 
4.3.9.1  Generate factory setting   (P052 = 1 or P970 = 0) 
This function is used to reset the parameter values, in accordance with a) the parameter list (dispatch status for 
the unit; see Section 5, column 4) and b) parameter P077 (see below). Only the settings of parameters P070 
(MLFB) and P077 (type of factory setting) remain unchanged. 
The MLFB-dependent parameters P071, P075 and P076 are set in accordance with the type of the 
rectifier/regenerating unit (see Section 4.3.9.2 "Initialization"). 
The parameters dependent on P077 are set in accordance with the table shown below. 
In the normal case (P070=0), the values listed in the parameter list in Section 5 are used as factory settings, so 
the table shown below does not have to be considered. 
For fast parameterization of special functions, using P077=1 to 6, an appropriate set of factory settings can be 
selected for certain parameters in accordance with the table shown below. In this manner, for example, certain 
terminals of the basic unit can be parameterized fast as sources for certain control word functions. 
The following table shows the factory settings for the parameters that are dependent on P077:
