- Switching operation
According to the switching methods above, diameter/radius
specification is internally switched as described below.
1) Switching using a signal
- When parameter DIAx = 0 (radius specification) → Operation
is performed with diameter specification.
- When parameter DIAx = 1 (diameter specification) →
Operation is performed with radius specification.
2) Switching using a G code
- When the specified address value = 0 (radius specification) →
Operation is performed with radius specification.
- When the specified address value = 1 (diameter specification)
→ Operation is performed with diameter specification.
NOTE
1 When the diameter/radius specification switching
state is to be cancelled using a reset or mode
switching at the time of signal-based switching, the
input signal needs to be operated.
2 Switching using a G code is cancelled by a reset.
CAUTION
When switching is performed from diameter
specification to radius specification, the travel
distance based on the same move command is
doubled when compared with diameter
specification. So, when switching from diameter
specification to radius specification, ensure safety
in machine operation.
Limitation
- Feedrate
A radius-based feedrate is specified in both of diameter specification
and radius specification at all times.
- Data not switchable
The following data follows the setting of parameter DIAx, so that
diameter/radius specification switching is not performed:
- Parameter
- Offset
- Workpiece coordinate system
- Scale display on the graphic screen
NOTE
For offset data, the settings of bit 1 (ORC) of
parameter No. 5004 and bit 2 (ODI) of parameter
No. 5004 have priority.
