FANUC Series 30i-MODEL A
External Data Input
External workpiece coordinate system shift
In the external workpiece coordinate system shift, the shift value can be
externally modified by the signal of PMC.
Each axis has this shift value (parameter No. 1220), and this shift value is
added to all the workpiece coordinate systems in common.
The shift value is not lost by cutting off the power supply.
The shift value can not only be added to the current work coordinate system
shift but also be substituted for the current value.
The value range is 0 to + / - 79999999.
The unit and setting range are the same as the Tool offset.
NOTE
1 If Parameter EED (No.6301#3) is set to “1”, the Data area
can be specified by 32bit data specification.
Under the setting, the external tool compensation range is up
to +/ - 79999999.
External machine zero point shift
The machine coordinate system can be externally shifted by inputting a shift
value.
When the shift value is input, compensation is immediately applied to the
corresponding axis and the axis moves. The position accuracy can be
improved by combining this function with sensors.
The specification to shift the axis is the same as the external workpiece
coordinate system shift.
The compensation value is specified in signals ED0 to ED15 using a binary
code ranging from 0 to +/
- 9999. This compensation value must be
specified in absolute value. The value which the machine actually moves at
input is the difference from the previously stored value.
After the Reference point is established, this function becomes effective. The
shift amount is memorized though the machine is not moved when the shift
amount is input before the Reference point is established. When the
Reference point is established afterwards, the machine is moved for the
memorized shift amount.
NOTE
- If Parameter EEX (No.6300#7) is set to “1”, the Data area
can be specified by 32bit data specification.
Under the setting, the external machine zero point shift range
is up to +/ - 999999999.
Caution
- When a large value of compensation is applied at one time,
an alarm such as "excessive error on stop" may occur. In this
case, input the compensation in several smaller increments.
