Machine data:
Max. line speed =400m/min
Rated speed of the motor winder/unwinder Vn = 3000rpm
Max. diameter of the winder/unwinder = 700mm
Min. diameter of the winder/unwinder = 100mm
Reduction ratio motor-coil = 0.5
One pitch dancer
Dancer stroke from the lower limit switch to the position of electric 0 = 160mm
The drive of the winder/unwinder must be sent the analog signals regarding line speed and the position of the
dancer (whose potentiometer will be supplied between the terminals -10V... +10V) and the digital commands
regarding the enabling of the PID control.
The regulator output will be sent to the speed reference 1.
Drive setting: (below are only the parameters regarding the PID function)
Input/output
Set
Analog input 1
as input for the wiper of the dancer.
Analog input 1 / Select input 1= PID Feed-back
Set
Analog input 2
as line speed input (feed- forward).
To set the feed-forward on an analog input, seeing that this one is not directly accesible in the list of high-priority
parameters, it is necessary to pass through a supporting parameter
