0:
format. This mode maps decimal numbers inaccurately if this format's 52-bit wide
mantissa is inadequate to map the number in binary notation. To solve this problem,
all comparison commands ( ==, <>, >=, <=, > and < ) are checked for relative equality
of 1E-12.

than SW 6.4)

can be programmed in the part program. The channel name can thus also be programmed
instead of a numerical value for the channel number in programming coordination

is activated. This means that all invalid ASCII characters in a part program block are
internally handled as blank.

10284 DISPLAY_FUNCTION_MASK
- Behavior of various display variables
-
- -
Description:
Bit mask for parameterizing various display variables:
BitNo.
Bit0:
Parameters are assigned to the OPI variable lastBlockNoStr in the SPARP and SPARPP
blocks.
Bit1:
Concerns the OPI variable cmdSpeed in the SPARPP block. If the bit is set, the variable
returns the programmed speed even if the spindle is at a standstill or in another mode
(positioning mode, axis mode).
Bit2
Concerns the OPI variable cmdSpeed in the SPARPP block. (reserved for constant cutting
speed)
Bit8:
Servotrace manages larger numerical values internally. Overruns in data format are
avoided. The accuracy may be reduced with large numerical values.

0x1 Comparison commands ">" and "<" are processed as for SW 6.3 and earlier:
Sub-program data of the type REAL are mapped internally in the IEEE 64 bit
This procedure is deactivated for greater than (>) and less than ( < )
0x2 Programming the channel names from machine data MD20000 $MC_CHAN_NAME
By setting bit 1, the channel name stored in machine data MD20000 $MC_CHAN_NAME

By setting bit3, the previous behavior when interpreting a part program block
0x10 The wait time G4 F<wait time> is rounded off as a multiple integer
This means that a G4 F0.001 only takes one cycle, for an Ipo cycle of 1 msec.
