No. Error Messages Description
3 2ms Reentrancy Fault The system did not finish the required calculations in
the previous 2ms position loop update in time for the
next position loop update.
4 Math Overflow A math overflow occurred (a calculation exceeded the
internal system limit). Check the values of the
variables used in the program.
5 Divide by Zero A division by zero calculation was attempted. Check
the values of the variables used in the program.
6 LOOP variable range A variable used as the count for a LOOP statement
was out of range. The valid range of a LOOP count is 0
to 65535.
8 PRECISION Out of Range Decimal point precision is not within the range of 0 to
4.
9 BCD Input Range A number larger than 9 was read in as a BCD number
in a BCD statement in a program. Check the inputs that
are being used for the BCD input.
12 LOOP Count Out of Range Loop constant value is not within the range of 0 to
65535.
13 Profile Calculation The move cannot be made based on the parameters
for the move: distance, velocity, acceleration, or time.
Possible causes are variable values used for the move
parameters that result in an acceleration or time of 0.
16 Invalid Opcode The GML tried to execute a program opcode that was
not valid (programs are compiled into opcodes that the
GML executes). Compile the program again to make
sure it compiles correctly.
17 Home Not Defined Home has not been defined when trying to execute a
MOVP (absolute) move. Run the Home program or
Define Home and execute the MOVP command again.
19 Delay Out of Range Time value for a Delay statement is greater than
65,535 seconds.

KFF Out of Range
KI Out of Range
KPZ Out of Range The parameter listed has exceeded the internal system
limit. The limit is determined at run time based on the
Scale parameter. Check the gain values under the
Parameter menu.
24 Gear Out Of Range The calculated value for the gear ratio denominator is
greater than 32,767. Check that the value is correct.

on the Scale parameter. Check the velocity and
acceleration values under the Parameter menu.
