Analog Output Signal Function For Dancer Tension Setting - Mitsubishi Electric A800 Plus Series Function Manual

Dancer feedback speed control details
3.5.16
Analog output signal function for dancer tension
setting
The dancer tension command can be used for controlling the dancer roll using an air cylinder. The dancer tension command
can be output through terminal FM/CA or terminal AM.
The dancer tension setting can be input by setting parameters or through an analog input terminal.
By setting the dancer tension, taper ratio, and winding diameter at taper start, the analog output signal for dancer tension
control can be calculated based on the winding diameter determined by winding diameter calculation.

Description
The primary delay filter time constant to the analog
input is selectable. A larger setting results in slower
response.
The tension setting is input through terminal 2.
The tension setting is input through terminal 4.
The tension setting is input through terminal 1.
The tension setting is input through terminal 6 (FR-
A8AZ).
No function
Set the bias tension.
Set the gain tension.
Set the maximum value for dancer tension setting.
Tension setting through analog input terminal
Set the primary delay filter time constant to the analog
input.
As set in Pr.74.
Second function of Pr.826 (enabled when the RT signal
is ON)
As set in Pr.826 or Pr.74.

The taper ratio is input through terminal 2.
The taper ratio is input through terminal 4.
The taper ratio is input through terminal 1.
The taper ratio is input through terminal 6 (FR-A8AZ).
No function
Set the winding diameter to start taper control.
Taper control is started at the minimum winding
diameter.
Set the taper ratio.
The taper ratio is set through the analog input terminal.
