3.2.3.11 Stretching, compression, offset of the Y axis

) 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 Mode

Result if input CDATA−XFACT =

100 % −100 % >100% <100%

DFIN @XFACT

100%

No stretching,

No stretching,

backward direction)

Compression Stretching

DFIN @ 100%

XFACT

See TIP below Stretching Compression

) 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.
