Detailed Description
2.5 Toolholder with orientation capability
Tool Compensation (W1)
2-106 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
• The two vectors v
1
and v
2,
that describe the rotary axes, must be defined (i.e., must not be
equal to zero).
• The two vectors v
1
and v
2
must be perpendicular to each other.
• The tool orientation must be perpendicular to the second rotary axis.
Non-defined orientation
If these conditions are not satisfied and an orientation that cannot be achieved by an active
frame is requested with TCOFR, an alarm is output.
Vector/angle of rotation dependencies
If vector v
1
or v
2
, which describes the direction of a rotary axis, is set to zero, the associated
angle of rotation α1or α2 must also be set to zero. Otherwise, an alarm is produced. The
alarm is not output until the toolholder is activated, i.e., when the toolholder is changed.
Tool fine compensation combined with orientation
Tool fine compensations and toolholders cannot be combined. The activation of tool fine
compensation when a toolholder is active, and vice versa the activation of the toolholder
when tool fine compensation is active, produces an alarm.
Automatic toolholder selection, RESET
Machine data:
MD20126 $MC_TOOL_CARRIER_RESET_VALUE
can be used to select a toolholder automatically on RESET or program start, and is treated
in the same way as the controlled selection of a tool via machine data:
MD20120 $MC_TOOL_RESET_VALUE.
Behavior on RESET or during program start is controlled via bit 6 in machine data:
MD20110 $MC_RESET_MODE_MASK
or
MD20112 $MC_START_MODE_MASK;
this is the same bit that is used in tool selection.
