Simulation and simultaneous recording
In order that simulation and simultaneous recording are displayed without any errors, set the
machine data as described in the following section:
Setting the technology for simulation (Page 139)
Defining the direction of rotation
In order that the direction of rotation is correctly displayed in the ShopMill user interface, and
when programming ShopMill functions, the correct direction of rotation is executed, you must
make some settings that are coordinated with one another. You must align these settings to
the actual direction of rotation of the axis at the machine.
MD52207 $MCS_USAGE_ATTRIB[n]
Bit 4
Bit 5
Specify other direction of rotation for position pattern
You can specify a position pattern for the tool axis. Rather than Bit 12, you must set Bit10 to
active in the MD52207 so that, for example, the position pattern can be machined on rotary
axis C with an appropriate swivel position.
MD52207 $MCS_USAGE_ATTRIB[n]

Bit 4
Bit 5
Bit 6
Bit 7
Bit 8
Bit 10

Displayed direction of rotation for M3 is counter-clockwise (for spindles)
Direction of rotation M3 corresponds to rotary axis minus (for spindles)
This bit must be set analog to PLC bit DB31, ... DBX17.6!
Rotates around 3rd geometry axis (for rotary axes)
Displayed direction of rotation for M3 is counter-clockwise (for spindles)
The viewing direction can be selected. Either from the interior looking out or from outside
looking toward the spindle.
However, the same selection must be made for all spindles.
Direction of rotation for M3 corresponds to rotary axis minus (for spindles)
Display rotary axis as offset target for measuring
Offer rotary axis in position pattern
The orientation of the axis is determined with Bits 0 to 2.
If one of the Bits 10 to 12 is set, they determine the orientation of the axis for position patterns.
Offer rotary axis for blank clamping (on milling machines)
The orientation of the axis is determined with Bits 0 to 2.
Rotary axes turns around the 1st geometry axis (only for position pattern)
Tapping also without encoder
The setting depends on whether at the machine the tool spindle is equipped with an encoder.
= 0 Tapping only possible with encoder
