Dear Experts, I am working with steel cutting machine. This machine have 4 number of axis, which is used for Sinamics V90 drives. I am using EPOS postion control with S7-1500 PLC with servo motors. 3 Number of axis(Feeding, Cutting and Traversing) commissioning is OK and working fine. Problem is 1 axis(Forming) i can not get proper actual velocity and actual speed. The axis is configured for Modulo axis(360mm), machanics data(2/3 gear ratio) and i am giving values( SET VELOCITY (480000MM/MIN), SET POSITION(360MM), ACCEL(100%), DECEL(100%) and OVERRIDE(100%)) from PLC(s7-1500). Whatever Set velocity i am giving from PLC, the drive only running with 21300 MM/Min Actual velocity and 90rpm speed. I tried all the possible ways to change the parameters like machanics data change, Max velocity, Max accel, Max decel, Autotuning with maximum dynamic factor, change set values from PLC,,, But always same response from the drive( 90rpm and 21300 Mm/min actual velocity). I can not able to figure out what actual problem in the axis. Even i tried with factory reset and another machine with same congiguration(only problem with same axis). always same response from the drive. But in Control panel speed run it will run upto rated speed(2000rpm), even position jog control from PLC its working fine with set jog speed with set jog velocity. I have attached V90 project backup for your refference. Kindly provide what i need to do to increase the speed and get good responce. AttachmentForming drive.zip (334 Downloads) |
