Minimum diameter Value of the minimum diameter in [mm].
Maximum diameter Value of the maximum diameter in [m].
Line spd source
Number of the sampling parameter for the line speed. In order to obtain the real number
to be set, it is necessary to add +2000H (8192 decimal) to the parameter number.
Programming example for the encoder 1 (connector XE1) on Line speed source:
OPTION Menu
————> Torque winder
————> Diam calculation
————> Line speed source = 8619
Paragraph 10.4. “List of the high priority parameters’ shows that Enc 1 speed has the
decimal number 427. In order to obtain the value to be entered it is necessary to add
8192 decimal (fixed offset): 8192 + 427 = 8619
Programming example for the analog input 2 on Line speed source:
a) input programming on a PAD parameter

————> Analog input 2
————> Select input 2 = PAD 0
b) setting of PAD 0 as a line speed input:
OPTION Menu
————> Torque winder
————> Diam calculation
————> Line speed source = 8695
Paragraph 10.4. “List of the high priority parameters’ shows that PAD 0 has the deci-
mal number 503. In order to obtain the value to be entered it is necessary to add 8192
decimal (fixed offset): 8192 + 503 = 8695
Line speed gain Calibration value for the line speed.
Its setting depends on the sampling parameter of the line speed; it is used to obtain “Line
speed” = 100% at its maximum value
The calculation of Line speed gain must be carried out with the formula:
[32768 x 16384 / (maximum value of the sampling parameter x 8)] -1

If the encoder has an unknown rotation speed, the input value of the encoder 1 can be
