OUTLINE OF THE DEDICATED FUNCTIONS

1 OUTLINE OF THE DEDICATED FUNCTIONS

The following dedicated functions for winding and unwinding machine are added to FR-A700 series standard inverter. In this

supplementary instruction manual, specifications of the new functions are included. Refer to the FR-A700 Instruction Manuals

for functions not explained in this supplementary instruction manual.

This product is useful when difference between minimum diameter and maximum diameter is great and when feeding speed

is fast in winding machine with dancer roll.

The inverter torque is controlled by the tension control, inertia compensation and mechanical loss compensation. Thus,

dancer rolls and tension controllers are not required to roll up a sheet of paper when using this product.

This product is also useful for wiredrawing machine and to roll up paper in a printer.

• Dancer control function

• Winding diameter compensation function

• Tension control function

The following table shows valid control methods for each function.

REMARKS

• While the dancer/tension control selection X83 signal is ON, the setting values of Pr. 731 to Pr. 734 and Pr. 763 have higher precedence

over the other assigned terminal settings such as Pr. 868, Pr. 785 = "1", and Pr. 406. (Example: When Pr. 731 = "5" and Pr. 868 = "0", the

terminal 1 is set to the dancer signal input.)

• For the taper setting analog input, the setting of Pr. 785 Terminal 4 function setting has higher precedence.

• While tension control is valid (Pr. 800 = "6 or 16"), the following parameter settings are invalid: Pr. 731 Dancer signal input selection,

Pr. 732 Dancer main speed command input selection, and Pr. 734 Dancer tension setting input selection.

• The dedicated-function parameters take the following precedence over each other. When several functions are assigned to a terminal,

input to the function of lower precedence is regarded as 0.

Terminal 4 function setting (Pr. 785 = "2") > Pr. 731 Dancer signal input selection > Pr. 763 Line speed input selection > Pr. 732 Dancer main speed

command input selection > Pr. 733 Taper setting analog input selection > Pr. 734 Dancer tension setting input selection.

Gain adjustment in actual operation

3.6 Gain adjustment in actual operation

Prepare rolls of minimum, medium, and maximum diameters. (If a roll of medium diameter is not available, obtain P/I gain by

calculation.)

Adjust

• Speed control "P" gain, speed control "I" gain (Real sensorless vector control/Vector control)

• Dancer "PID" gain

3.6.1 Speed control P/I gain adjustment (Real sensorless vector control/Vector control)

Set "P" gain as high as possible without setting "I" gain as a basic principle so that inverter acting as a proportional amplifier

returns high response to the command from dancer roll.

Before sending material, adjust dancer roll by applying load to each spool shaft.

At this time, at least make adjustment with maximum diameter roll and minimum diameter roll.
