prior to invoking the target position
Example: The examples below will help you understand positioning from a positive and from a
negative direction:
Position data for the target position to be approached:
Position value for the target position: 1000 increments
Distance value to range BEE1: 300 increments
Distance value to range BEE2: 100 increments
Distance value to range BEE3: 70 increments
a) Approaching the target position in positive direction. When the position is selected, the axis is
at 400 increments. The axis must travel in a positive direction at the rapid traverse rate.
• When the actual value is 700, the traverse rate is switched to creep speed.
• When the actual value is 900, the drive is switched off.
• When the actual value is 930, the target position has been reached.
The IP 240 monitors the actual value range 930 to 1070, and signals exiting of this target
range without a new position having been selected.
