MOTOR_I_CALC
Lists the formula to calculate the maximum amp value for various types of
components on a per motor type basis. Each row gives a motor type followed
by columns marked with the codes given in the MOTOR_I_DESC table. Each
cell contains an expression to calculate a FLA value. The FLA value for the
selected motor corresponds to the symbol "I" in the expression.
Valid operations are +-*/^. The “^” character is the exponential function. For
example, I^2 is I squared, while I^0.5 is the square root of I.
If-then-else statements are supported including one level of nested statements.
For example,
■ (if (I > 400) then (I * 8) else (I * 11)) - the calculated amp value is eight
times FLA current for 0-400 amps and 11 times for greater than FLA of 400
amps. One level of nesting is supported.
■ (if (I >= 9.0) then (I * 1.25) else if (I < 2.0) then (I * 3.0) else (I * 1.67) - the
calculated value is set to (I * 1.67) if I is less than 9 but greater or equal to
2.0 amps. If I is less than 2.0 amps the calculated value is (I * 3.0), and if
greater than or equal to 9.0 amps, it is (I * 1.25).
Valid Boolean operations are >, <. >=. <=, =.
MOTOR_I_MAP
Maps the calculated FLA for a component to a specific rating value and an
optional catalog assignment. The rating value is annotated to the symbol
using the API call c:ace_cb_anno2 in the circuit builder spreadsheet.
The optional catalog assignment is defined in the Default field. Use the
following format:
MFG={manufacturer};CAT={catalog};ASSYCODE={assembly code}
If the ASSYCODE value is not needed, use the format:
MFG={manufacturer};CAT={catalog}
CATALOGSEL table
Circuit Builder uses the CATALOGSEL table to save the catalog selections made
for the motor and other components. The catalog information is saved based
on the motor size. If this same motor size is used later on another circuit, these
previous catalog selections become the default values when they match up
with the configured selections. For example, if the previous circuit was
configured with a 10HP motor with time-delay fuses, and a 10HP motor with
