Alarm CODE 1, 2, 4, 5: generated if there are hardware problems in the communication
with the drive. Replace DGF or Regulation card, check XO
connections. See table 2.2.2.2.
Alarm CODE 6: generated if an error code in the mathematics co-processor is
detected (e.g. zero indexing). The possible errors of the
mathematics co-processor are shown in the table 2.2.2.3. Check
the scheme for Mathematical error (E.g. division by 0).
MSG Exception Cause
DEFAULT
ACTION (If
exception is
Masked
IE
Invalid
Operation
Illegal Operation on a signal,
unsupported format, indeterminate
form (0
- ∞
, 0/0), (+ ∞ ) + (- ∞ ), etc.)
or stack overflow / underflow (SF is
also set)
Result is a quiet
NaN, integer
indefinite or BCD
indefinite
DE
Denormalized
operand
At least one of the operands is
denormalized, i.e. it has the
smallest exponent but a nonzero
significand The operand is
normalized, and
normal processing
continues
ZE Zero Divisor
The divisor is zero while the
dividend is a noninfinite, nonzero
number
Result is ∞
OE Overflow
The result is too large in magnitude
to fit in the specified format Result is largest
finite value
∞
UE Underflow
The true result is nonzero but too
small to be represented in the
specified format, and, if underflow
exception is masked,
denormalization causes loss of
accuracy
Result is
denormalized or
zero
PE
Inexact Result
(Precision)
The true result is not exactly
representable in the specified
format (e.g.1/3); the result is
rounded according to the rounding
mode
Normal processing
continues

Alarm CODE 7: generated if the execution cycle of the application code remains
active for a longer time than the max. time expected (50 ms).
This is possible if, for instance, there is an infinite loop in the
program. Increase execution time or reduce your application.
