nation
0626 Signal number
analog output terminals 75.x/15
... defines which signal is output.
In this case, the appropriate signal number must be entered from the "signal
selection list for analog output" (refer to table 6-56).
0627 Shift factor
analog output terminals 75.x/15
... defines the shift factor, with which the output signal is manipulated (refer to
Fig. 6-60).
Only an 8 bit output window can be output from a 24/48 bit signal due to the
8–bit resolution. The shift factor can be used to define which eight of the 24/38
bits are located in the output window and should be output.
A shift factor for each signal is recommended in the signal selection list for
analog outputs (refer to Table 6-56).
0628 Offset analog output terminal
75.x/15
... specifies an offset to the 8–bit output signal.

... smooths the output signal with a 1st order proportional element (PT1 ele-

SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
Parameters
Name
The signal to be output is shifted by 20/256 V (78 mV) by changing the
offset by 1 digit.
P0628 = –128 8 –10 V, P0628 = 127 8 +10 V
Overcontrol protection on (standard)
The bits above the 8–bit wide window cause +10 V or –10 V to be
output, i.e. the output is not overcontrolled.
Over–control protection off
The bits above the 8–bit wide window are ignored. The analog
value is exclusively defined by the 8–bit window, i.e. the output can
be overcontrolled.
low smoothing time ––> low smoothing effect
high smoothing time ––> high smoothing effect
