I doing a new project using Mitsubishi PLC Q Series which require to roll up some cable into a drum. I trying few formula to row up to Synchronize the Motor Drum Speed with the Linear Stepper Motor speed
Cable Size : 10mm OD
Motor Drum Speed : 1.000 mtr/s (Fixed Speed)
0.75kw Brake motor with Inverter control
Drum Size
Inner Shaft OD : 318 Diameter
Inner Shaft Length : 100 mm
Linear Guide Stepper Motor length : 100mm
0.2kw Servo Motor using Delta ASD-B0221-A Driver
Setting at 10000 pulse speed equivalence moving 10 mm/s
Assuming of all condition above
from start to end of the inner shaft i will row up to 10 circle per row
1st row total roll up length = 10.0 mtr
2nd row total roll up length = 10.6 mtr
3rd row total roll up length = 11.2 mtr
4th row total roll up length = 11.9 mtr
5th row total roll up length = 12.5 mtr
as it increasing its own diameter after each row, by calculation it increasing by 6% each row
1st row stepper speed = 10 mm/s
2nd row stepper speed = 9.4 mm/s
3rd row stepper speed = 8.8 mm/s
4th row stepper speed = 8.3 mm/s
5th row stepper speed = 7.8 mm/s
I am decreasing the stepper motor speed 6% after each completed row
i have not try this yet, as all this is my theory only & also i attach my cable drum size & Linear guide stepper motor. i open to other suggestion, or there other formula for calculating the cable synchronize.
Thank you
Regards
