Thanks for posting Chris but the information you have provided is incomplete.
1200mm is not telling us much as you have not told us what this number represents. Is this your speed setting? If so, over what time interval? 1200mm/sec, per min? This part you have left out.
Sorry, but 23 what? Amps, percent, watts? I am not trying to be difficult here, but clarity and details will help us all benefit. Readers will have the best chance to “see” what you do and have an understanding of your issue. This gives you the best opportunity to receive accurate responses to your inquiry.
