Tension Controller TC818
5.2.2.2 Ratio
R(current radius)
Pulse N2[37]/r
Pulse N1[36]/r
Radius R0[35]
When using this monitoring method, the controller counts the pulses generated by the proximity switches which mounted
on the material roll and main roll(i.e. the
), the radius of the material will be calculated automatically
with the setting parameters. Thickness[02] and Wind Mode
[40]
ratio method.
The following parameters must be set properly:
1. Max Radius[33]
2. Min Radius[34]
6. Calc Cycle[38] When the sum of the pulses reach Calc Cycle[38], the calculation of radius will be updated once.
Calc Cycle[38] affects the interval and precision of the radius calculation, the greater value, the more precision but longer
interval.

The maximum radius of the roll, set the proper value according to real condition.
The minimum radius of the roll, set the proper value according to real condition.
3. Radius R0[35] The radius of the tension sensing roller.
4. Pulse N1[36] Pulses/revolution of the tension sensing roller.
5. Pulse N2[37] Pulses/revolution of the material roll.
