Description
Dancer tension command value
Pulse train input value (when the
actual line speed is input with
pulse signal)
Dancer roll set point
Dancer roll position
Dancer roll deviation from set
point
Winding length (upper 4 digits)
calculated in the inverter
Dancer roll position. It is displayed
even if the dancer feedback speed
control operating conditions are
not satisfied while the dancer
feedback speed control is enabled
(Pr.128 ≠ "0").
Commanded tension after taper
compensation
Commanded torque after winding
diameter compensation
Inertia compensation torque
Mechanical loss compensation
value
Voltage applied to terminal 1
Analog value input through
terminal 1 after calibration with
Pr.917 and Pr.918 settings
PID manipulated amount
A tension value measured under
torque control for tension control
with PID control enabled
A tension value manipulated
under torque control for tension
control with PID control enabled
Frequency (winding diameter
compensation speed) calculated
from the line speed command,
current winding diameter value,
and gear ratio when dancer
feedback speed control is valid
