Rapid-Air SERVO FEED: KBX SERIES User Manual

Page 23

The only section that has not been covered in this write-up is the ramp adjust mode.
The ramp adjusts how fast the servo motor gets up to speed and how fast it stops.
This feature is an asset that is seldom adjusted but can be a sure cure if material
slippage seems to be a problem. With the main menu screen displayed the key
labeled ramp is active. Pressing the ramp key produces this display.

Pressing the F1 or F2 keys will produce one of the following displays. The lower the

The ramp usually is factory set at .015 on the series 100 drives and .035 on the series
200 & 300 drives. There is some deviation to this when the factory runs the unit, but
this is a basic starting point.
