Function Application
‑657‑
When the terminal is activated, the system exits the tension control mode and the
AC drive restores general AC drive functions (the frequency source and torque
source are enabled based on the general AC drive functions).
8. DI function 61: Terminal tension rise
When the terminal is activated, the tension torque is increased by a certain ratio.
After the DI terminal is deactivated, the boost part will be canceled gradually based
on time.
9. DI functions 62 and 63: Thickness selection terminals 1 and 2
These functions provide material thickness switchover modes to meet different
requirements for materials with different thickness. For details of use, see B0‑31.
AO/Pulse output functions
In addition to the AC drive, PLC or actuators also affect the tension control function.
The AC drive supports output of variables related to tension control, enriching means
to realize the tension control function.
You can select AO/pulse output functions by setting F5‑06 to F5‑08.
1. Output function 19: External taper output
When the tension taper control is required and the material tension is determined
by the external actuator, you can enable this function to output taper.
2. Output function 20: Roll diameter output
When the roll diameter is calculated in the AC drive and the calculation result
needs to be output, you can enable this function to output the result.
3. Output function 21: Tension output
You can enable this function to output the tension reference of the AC drive. The
actual valid tension after taper calculation is calibrated based on the maximum
tension (B1‑02).
3.6.19Monitoring
You can set F7‑04 and F7‑05 to enable the display of the roll diameter or tension at
stop or during operation.
