Parameter Description
U608* If the master setpoint exceeds the clutch position, the
CouplePosition engaging/disengaging cycle is started, prior to which the
enable signal must be given.
2608
Function diagram [834.3]
U609* Index 1:
S.OffsetClutchP
Selection of the offset value for the engaging position
2609 during engaging/disengaging action. This value is added
to the engaging position in parameter U608.
Index 2:
Selection of the disengaging position. Only effective if
configuration of engaging/disengaging U475 = 1 or 11.
Parameter U608 has no influence on the disengaging
position

U610* Index 1:
OnOff Ramp The parameter determines the number of LU increments
in which the engaging/disengaging action accelerates to
2610 master speed.
Index 2:
The parameter determines the number of LU increments
for the length of a ramp. This ramp can be freely wired via
KK0895.
Example: engaging (U475=0)
----------------------------
Ramp = 10000 LU increments
Engaging length = 100000 LU increments
==> After the start of engaging action, the drive
accelerates in (ramp/2) =5000 inc. up to the master
speed, travels synchronously along the (engaging length
ramp) = (100000-10000) = 90000 inc. with the master
setpoint and is then shut down in 5000 increments.
Function diagram [834a.4]
Example: engaging (U475=11)
-----------------------------
Acceleration ramp = U610.1:
Interconnection of KK0894 to U474.1 results in =>
Src.variable acceleration ramp in LU increments referred
to master
Deceleration ramp
= U610.2:
Interconnection of KK0895 to U474.2 results in =>
Src.variable deceleration ramp in LU increments referred
to master
Function diagram [834b.4]8
U611* The parameter determines the number of increments for
OnOff Length the master setpoint which are to be engaged/disengaged
in total. Example see U610.
