Motor starting current will be 5-6 times for DOL as said by Ayman Elotaify For drive, you will not have such peak. It depends upon control mode you use and rampup time. Lets take example of V/F, and 5 Sec time, in such case drive will start 0V, 0Hz and slowly increase frequency and voltage and this will not allow starting pick If your ramp up time is say 0.2 sec, its almost like DOL,so you may have starting pick but here also lesser compare to DOL If you are using close loop control, your starting pick will reduce more Hope this helps, Regards, Devesh Vithani |
