5.4.3 Reel diameter internal calculation method
• Tension characteristics - - - - - - - - - - Refer to the figure as right.
[1] While regarding the tension obtained at 0 mm reel
diameter (virtual winding diameter) as 100% (set tension),
the controller reduces the target tension as the reel
diameter increases.
Since the reel diameter is larger than 0 mm when starting
the winding operation, the target tension will be smaller
than the set tension at starting operation.
[2] When the control output of this controller is 100%, the
torque generated by the actuator will be regarded as
Tmax. The target tension is reduced depending on the
winding diameter as shown in the right figure.
5.4.4 External reel diameter signal method
• The reel diameter signal function is assigned to the AI1 or AI2
input terminals. Depending on the obtained reel diameter, 0 to 5
V signal will be associated (0 V for minimum diameter, 5 V for
maximum diameter).
• The target tension will be subject to change depending on the
winding diameter signal as shown in the right figure (linear
characteristic).
• To use the reel diameter signal, select item number 51 in the
adjustment mode, and then assign it to the reel diameter signal
function to the AI1 or AI2 terminal.- - - - - - - - - Refer to Sec. 6.2.
5.4.5 Taper rate setting
• Set the taper rate using one of the following methods.
[1] Set the taper rate using the taper rate setting screen.
• On the normal operation mode screen, press the function key to move to the taper
rate setting screen, and then set the taper rate using the setting dial(16).
[2] Set the taper rate using the external analog voltage signal.
• Assign the taper rate setting signal to either [AI1] or [AI2], and set the taper rate using this
signal.
• Reel diameter internal calculation method
Input voltage = 0 to 5 V
→
Taper rate = 0 to 80%
• External reel diameter signal method
Input voltage = 0 to 5 V
→
Taper rate = 0 to 100%
• To use the taper rate setting signal, select item number 51
in the adjustment mode, and then assign the taper rate
setting signal function to the [AI1] or [AI2] terminal.
- - - - - - - - - - - - - - - - Refer to Sec. 6.2.
• When the taper rate setting signal function is assigned to either [AI1] or
[AI2], the taper rate cannot be set by using the setting dial(16) on the
panel.
