1.16.3 Control of Winders/Unwinders with Dancer

1.16.3.1 Machine Data

Maximum line speed =400m/min
Rated speed of the winder motor Vn = 3000rpm
Winder maximum diameter = 700mm
Winder minimum diameter = 100mm
Motor-winder reduction ratio = 0.5
One-pitch dancer
Dancer stroke from the lower limit switch to the electric 0 position = 160mm
The winder/unwinder Drive must receive the analog signals referring to the line speed and to the dancer position
(whose potentiometer is power supplied at its ends with values included between -10... +10V) and the digital
commands referring to the PID control enabling.
The regulator output is sent to the speed 1 reference.

1.16.3.2 Input/Output

Drive settings: (only those referring to the PID function are described)
Connect to the analog input 1 the Dancer cursor.
Select PID fbk src = An inp 1 output
Connect to the analog input 2 the line speed reference (feed- forward).
