Warner Electric CBC-1000 - Manual (Page 8)

Function Key Definitions
Count The actual move distance, in pulses or scaled into engineering units (inches, feet, rotations, degrees, etc.) displayed
dynamically.
Move Preset The desired move distance in pulses or scaled into engineering units. This is the value the operator enters to select a
new move distance.It can also be locked during the RUN mode by simply programming line 6 to “off”.
Early Warning A distance prior to Move Preset at which the early warning output is activated. Expressed as pulses or engineering
units, this output can be used to accomplish a soft brake (slow down), energize valves, etc.
Batch A cumulative batch counter that can be dynamically displayed to show the number of operations, cycles, etc. When
this counter reaches the value programmed by the Batch Preset (key 7) the Batch Complete Output (pin 21 on
CBC-1000) is activated. The batch counter can be manually or automatically reset.
Batch Preset A programmable batch counter activates the batch complete output when the value programmed has been reached
by the batch (key 6).
Braking Distance The actual distance required to stop. This value is dynamically updated to determine the brake actuation point.
Factory default is 25 pulses or engineering units which is only used for the first cycle after power-up. After the first
cycle the CBC-1000 will tune to the braking distance required.
