Hi..
For cut length application, how to define accuracy of cutting length (we need +/- 1mm)? I used compactlogix with 2048 ppr encoder and measuring wheel diameter is 127mm. The drive unit is using ControlTech Unidrive SP2402 c/w dynamic braking resistor and vector motor. Maximum speed is 30 MPM, maximum cut length is 1800 mm. How to convert pulse to length?
Compactlogix will generate speed ref to unidrive and if actual length reached 90% and motor speed will slowdown and stop if actual length reached setpoint.
Any idea or suggestion?
Thank you.
James
