PARAM 61.06 Source selected by 61.06 SPD MTCH REF PTR. 10
61.02 SPD MATCH W/TRIM Selects if core speed match is enabled when dancer or tension control
is active.
OFF DAN/TEN Function is disabled when dancer or tension control is active. 0
ON DAN/TEN Function is enabled when dancer or tension control is active. 65535
61.03 SPD MTCH RANGE +/- Maximum trim allowed. Example: If 10% is entered, a minimum input
(0 VDC / 0 mA) yields a –10% trim value. A maximum input (10 VDC /
20 mA) yields a +10% trim value.
0…500% Setting range. Typically 5%. 1 = 1%
61.04 DIGITL POT RATEms Rate of change for the Speed Match when Digital Inputs are selected
for the Speed Match Setpoint. The Digital Inputs act as an increase/
decrease setpoint adjustment: “Digital Pot”.
100…32767 ms Setting range. 1 = 1 ms
61.06 SPD MTCH REF PTR Defines the source or constant for selection PARAM 61.06 of 61.01
SPD MTCH REF SEL; C10000 gives 0% trim.

62 DANCER CONTROLS
Dancer control and PI regulator setup.
Note: This group is hidden unless a Dancer macro is selected.
62.01 P-GAIN 1 MIN Sets the immediate reaction step of the PI regulator. 62.01 P-GAIN 1
MIN sets the gain at 65.01 MIN CORE DIAMETER and 62.02 P-GAIN
1 MAX sets the gain at 65.02 MAX ROLL DIAMETER; the gain is
linear between these two points. Typically, 62.02 P-GAIN 1 MAX is set
larger to compensate for the increased inertia of larger roll diameters.
The default values give a good starting point for the gain and they
should not be modified until the correct diameter is on the machine
and the machine is running. For example, do not adjust 62.02 P-GAIN
1 MAX when the roll is around core. Likewise, do not adjust 62.01 P-
GAIN 1 MIN when the roll is built up. Note that too large of a gain
could lead to instability.
0.01…1000.00 K Setting range. 100 = 1 K
62.02 P-GAIN 1 MAX See 62.01P-GAIN 1 MIN.
P-GAIN 1 MIN…1000.00 K Setting range. 100 = 1 K
62.03 INTEG TIME 1 Integration time of the dancer PI regulator. The default value gives a
good starting point for the integration time of the PI regulator. A lower
integration time results in a more responsive system; however, too low
of an integration time can lead to instability.
10…10000.00 ms Setting range. 1 = 1 ms
