)
Note!
This operating mode only works with digital frequency preselection (chapter 3.2.3.3),
i.e. CDATA−DFIN must be selected with C1332 = 0.
Stretching / compression
The code C1319 serves to set the mode for stretching or compression. Two modes are used for
differentiation:
C1319

Note!
l
Values < 1% are internally limited to +1% at input XFACT via C1319=1
(compression).
l
If you do not want a stretching or compression, connect CDATA−XFACT to
FIXED100% (Lenze setting).
Offset
Use input CDATA−XOFFS to shift the X position by a constant value.
(
Stop!
The drive follows this position change with the max. possible torque! This is why
l
CDATA−XOFFS should be changed while the drive is in a latch phase or
l
a ramp function generator (e.g. RFGPHx) should be used.
