5) Set the "MAXIMUM CURRENT” Current, using the table on Chapter 4.5 , 4.6.
6) Set the Acceleration Delay requirements for the machine. Test the parameters in both
directions.
7) Set the FREQUENCY CREEP level starting from level 0.6 Hz. The machine should just
move when the accelerator microswitch is closed. Increase the Level accordingly.
8) Set the Speed Reductions as required. Make adjustments to “CUTBACK SPEED”
