Time acc/dec min Set the time in [s] corresponding to the lowest acceleration, deceleration and fast de-
celeration time.
Set time acc/dec min =15sec (time required for a fast deceleration)
Acc/dec filter Filter in [ms] on the acceleration calculation inside the drive
Set =30 msec
Mat width Width of the wound material as a percentage of the maximum width. Set =100%
Constant J comp Compensation of the fixed section (motor, reducer,core) as a percentage of the drive
rated current. Increase the value till the motor can increase the speed following the line
reference. During this phase the converter has always to be within the current limit.
· Diameter calculation function disabled (enable the programmed digital input as
Dis diam calc)
· Operations to be carried out without material on the machine,
· Install the empty winder (check that the parameter Roll diameter= min. diam).
Check that the parameters Constant J comp- Variable J comp=0
· Set the tension (tension ref)=0
· Minimum jog function and line reference
· Carry out some changes on the line reference.
· Increase gradually the value of the parameter Constant J comp till the winder/un-
winder is able to follow the line speed reference.
Variable J comp Torque compensation due to the wound material as a percentage of the drive rated current.
· Operation to be carried out without material on the machine
· Install a full coil on the winder (check that the parameter Roll diameter= max.
diam ).
· Follow the same procedure as the one carried out for the tuning of Constant J
comp
Act var J comp Monitor for the compensation of the variable section as a percentage of the drive rated
current.
Act const J comp Monitor for the compensation of the fixed section as a percentage of the drive rated
current.
Act comp Monitor for the compensations (it sums up static, dynamic and inertial frictions) as a
percentage of the drive rated current.
