0 If no zero signal was detected, the drive searches for the zero signal
during two further revolutions. If still no zero signal can be detected,
the inverter signals the error îE.EnCì.
16 If no zero signal was detected, the inverter immediately signals the
error îE.EnCì.
Bit 5 Approach position from index 0.
0 No; after the reference point drive the drive stops at the reference
point.
32 Yes; after the reference point drive the position from index 0 is
approached. The setting îContinue profile = yesì of index 0 is ignored
(always no), the drive stops at the position.
Bit 6 Manual adjustment of the reference point.
0 No manual adjustment.
64 In the inching mode the drive is driven onto the reference point and
then bit 6 is set. The momentary position is taken over as reference
point. After completed standardization the bit 6 is set again to î0" and
the output function 29 îReference point drive completedì (see Chapter
6.3) is set.
Bit 7 This bit defines, whether the recorded position is valid. With bit 7 the
output function îReference point drive takes placeì can be set.
PS. 25 defines the max. speed to reach the position in index 0. Index
0 is not available for further positioning (par example Mode PS.31/25
target speed unequal 0).
0 No
128 With valid position the output function 29 îReference point drive
completedì (see Chapter 6.3) is set.
Bit 8 Checking of zero signal; this function is used for checking the
reference point switch.
0 No checking
256 Yes; after driving free of the reference point switch the path to the
zero signal is checked. If the zero signal is not within a range of º to
æ revolution the error îE.EnCì is triggered.
An automatically handling of the brakes is in the reference point approach mode
only possible if the brake is activated in Pn.34.
This parameter specifies the input, with which the current position is reset to the
reference point.
If this input is set during an active positioning,
1) the inverter remembers the path still to be travelled.
2) the current position is set onto the reference point position.
3) the inverter continues with the interrupted positioning.
After the positioning is completed the current position is = reference position +
residual distance. This must be especially observed, if the driving referencing (par
example for rotary indexing tables) is to be used, because the remaining distance
is not considered in the following positioning. A consecutive error occurs. This
problem can be resolved only with a special rotary table software.
