Configuring:
● MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT[ 1, AX5 ] = 1000
(Maximum speed of gear unit stage 1 = 1000 rpm)
● MD30455 $MA_MISC_FUNCTION_MASK[ AX5 ], bit 6 = 1
(Programming VELOLIM acts together for spindle and axis operation independent of the
programmed identifier)

Programming contour/orientation tolerance (CTOL, OTOL, ATOL)

Addresses CTOL, OTOL and ATOL can be used to adapt the machining tolerances -
parameterized using machine and setting data - for compressor functions, smoothing and
orientation smoothing in the part program.
The programmed tolerance values are valid until they are reprogrammed or deleted by
assigning a negative value. Further, they are deleted at the end of the program or a reset The
parameterized tolerance values become effective again after deletion.
Syntax
CTOL=<Value>
OTOL=<Value>
ATOL[<Axis>]=<Value>

; Limiting the maximum speed of spindle 1 to 90% of
1000 rpm.
; Limiting the maximum speed of spindle 1 to 45% of
1000 rpm, C is the axis identifier of S1.
