sponds to the number of times the input shaft rotates for the
number of times the output shaft rotates. These are integer val-
ues. If a 10:1 gear box is used, enter “10” for the gear box
input.
Gear Box Output:
If a mechanical gear box is used, enter the value which corre-
sponds to the number of times the input shaft rotates for the
number of times the output shaft rotates. These are integer val-
ues. If a 10:1 gear box is used, enter “1” for the gear box out-
put.
High Scan Setting:
This value determines the interval at which blocks are executed
in high scan programs. One block from each high scan program
will execute in this time interval, some will take longer based
on specific block conditions.
Load Type: Select either linear or rotary. Linear implies an axis that has
finite travel range. Rotary implies an axis that rotates in one
direction only, but with a cyclic period. When “Rotary” is
selected, the position data is automatically modularized to fit
within one cyclic period or machine cycle.
Low Scan Setting:
This value determines the interval at which blocks are executed
in low scan programs.
Machine Cycle: This is the maximum position value of the main axis. When
this value is reached, the position will indicate “0”. Machine
cycle is only applicable if Load Type is set to “Rotary”. If the
application is a rotary table, this value may be the same as the
Feed Constant. Note: If the machine cycle in user units does
not equate to an integer number of pulses, the positioning units
will drift. In this case, program an offset at periodic intervals to
compensate for lost pulses. See note at the beginning of the
System Property section about Machine Cycle limitations.
Motor Rated Speed:
Enter the rated speed of the motor in rpm.
User units: Select from “centimeters”, “degrees”, “inches”, “microns”,
“millimeters”, or “pulses”. Custom units may also be entered.
