Tension control parameter group 14
PARAMETER DESCRIPTION 301
When parameter 14-11(P.610) is 2，the winding radius is calculated by the encoder on the winding shaft. In this
condition, connect the pulse signal to the HDI terminal of the inverter and calculate the winding radius through the
pulse per cycle(14-21(P.619))，cycle per layer(14-22(P.620)),and the material thickness(14-24(P.622)).
When parameter 14-11(P.610) is 3，testing the winding radius with winding radius sensor, the input channel of the
sensor can be either analog value or pulse input.
Parameter 14-13(P.611) is used for setting the maximum winding radius. When parameter 14-11(P.610) is 3，the
maximum value of parameter 14-14,analog value or pulse signal must be set to correspond with the setting of
parameter 14-13(P.611).
Parameter 14-14(P.612) is used for setting winding shaft diameter. The winding radius calculated by the winding
radius calculation module of the inverter is limited by 14-13(P.611) and 14-14(P.612).
Parameter 14-15(P.613) is used for selecting the input terminal of the initial winding radius.
1.
When parameter 14-15(P.613) is 0，the winding radius is set by parameter 14-16(P.614)~14-18(P.616).The
initial value of the winding radius can be determined through two multi-function digital input terminals. The
selection of the initial winding radius is as follows:
Digital input terminal 1
Digital input terminal 2
Initial winding radius source
0

14-14(P.612)

2.
When parameter 14-15(P.613) is 1，the initial winding radius is determined by the analog value. When the
initial winding radius is not calculated from the hollow winding radius, the initial winding radius can be selected
by the digital input terminal. The default radius when winding is the diameter of the winding
shaft(14-14(P.612)).The default radius when releasing is the maximum winding radius(14-13(P.611)).
Parameter 14-19(P.617) is for setting the winding radius filtering coefficiency. This parameter is used to avoid fast
change of winding radius calculation(or input) result.
Parameter 14-20(P.618) is used for displaying the current winding radius.
Parameter 14-21(P.619)~14-28(P.626) is related to this parameter only when 14-11(P.610)=1 or 14-11(P.610)=2..
1.
Parameter 14-21(P.619) is the pulse per cycle. This setting is mandatory when 14-11(P.610)=2.
2.
Parameter 14-22(P.620) is cycle per wound layer，mostly used for wire.
3.
When parameter 14-23(P.621)=1，material thickness equals to analog input, the maximum value of analog
input corresponds to the value of 14-28(P.626).
4.
When 14-23(P.621) =0，the default material thickness is determined by parameter 14-24(P.622).The different
material thickness source can also be selected by the combination of digital input terminals and
14-24(P.622)~14-27(P.625)
