What happened?

I have small lead screw 4.76mm which I need to set for about 5000 steps per mm. I am not able to do it, because I am getting the following error: ERROR: Critical error in main_init: Stepping rate 1000000 steps/sec exceeds the maximum rate
125000]
Board is not booting. Right now when I set 500 steps per mm Z axis is moving 1mm when I move it by 10mm in the web interface.
