Gain 1 and Gain2 setting

• In the adjustment mode (power ON with DIP. SW8 OFF), select item number 11 to set these values.
• If it is not necessary to correct the inertia for acceleration or deceleration, it is not necessary to change the
initial values.

Taper control function

5.4.1

Outline of taper control

• Taper control is used to change the tension depending on the variation in reel diameter.
• Taper control is mainly used for winding operation. As the reel diameter increases, the controller reduces
the tension to prevent the material from winding too tight or too loose on the reel.
• Following two methods are presently available to determine the current reel diameter.
[1] Reel diameter internal calculation method
[2] External winding diameter signal method

Selection of taper control method

• Select the taper control method by DIP switch 2 and 3.

• If the tension is kept constant during automatic control, the control output will be changed in
proportion to the reel diameter. While judging the increase in the control output as an
increase in the winding diameter, the controller will judge the reel diameter.
• This method does not need the reel diameter signal, however, a mechanical loss, change in
the actuator torque characteristic, etc. may affect the taper control.
• The external analog voltage signal that is in proportion to the reel diameter is used for taper
control. Taper control which is proportional to a winding diameter is available.
