Lenze 8600 series - Gain Adjustment - Radius Signal

9.7.4 Gain adjustment - radius Signal
When selecting the dancer-Position control with diameter
evaluation of the setpoint, the gain of the radius Signal must be set
such that an appropriate output frequency is generated when
having a fixed setpoint and a certain radius.
Coarse adjustment:
1. Before adjusting the radius Signal, the analog inputs must be
set.
2. Set CO25 = -l-.
3. Calculate correction factor C027:
- Determine minimum radius as a voltage value
rmin [VI
= ren [mm] *
Distance Signal [V]
Distance a [nun]
- Calculate CO27 (1.25 [V] is an internal calculation factor)
CO27 = 1v25[vl =
1.25[V]. Distance a [mm]
rti, [V]
rmin[mm] . Distance Signal [V]
Example when using the values given in chapter 9.7.1:
rti, [V] = 150 mm .
8V
= 1.2v
1000 mm
CO27 = 1.25 = 1.042
1.2 v
4. Enter the calculated factor via C027.
In general, the gain of the radius Signal is set in such way that the
Speed setpoint is will not Change when having the minimum radius.

Deactivate dancer-Position control Cl 92 = OHz
Install empty core (with minimum diameter) or enter minimum
radius as voltage [V] across terminals 112
Activate controller enable
Enter maximum setpoint of the line Speed
Select analog setpoint input 1/2 using CO25 = -l-
Change CO27 until the field frequency entered in CO46 is
