FANUC Series 30i-MODEL A
Input of tool offset value measured B
The tool offset value to be set differs according to the method of determining the measuring
reference position.
・If touch sensor contact detection is based on a one-contact input
If touch sensor contact detection is based on a one–contact input (the TS1 parameter (bit 3 of
parameter No. 5004) is 1), when a contact detected signal (tool compensation amount write
signal +MIT1) is received from the touch sensor, which of the two directions of each axis is
involved is automatically determined according to several pulses stored as a result of the axis
movement that was made before the signal reception. So the number of interpolation cycles
related to the stored pulses must previously be set in parameter No. 5021.Once which of the
two directions of each axis is involved is automatically determined, the corresponding axis
direction is subjected to axis interlock to stop feeding, and the obtained tool compensation
amount is stored in tool compensation memory. If the directions of stored pulses are not
unified, or no pulse has been stored, for example, because the servo power has been shut off
(servo off) or no axis movement occurred, a alarm (PS5195) is issued.A PS alarm is issued
also if the tool moves along two axes (X–axis and Z–axis) simultaneously; move the tool
along one axis at a time.If a PS alarm is issued, no tool compensation amount will be set
up,resulting in the four directions (two axes) being subjected to interlock.
Note
1 Pulse storage for automatic decision is carried out in the
manual mode while the GOSQM <G039#7> (tool
compensation amount write mode select) signal is 1. Stored
pulses are lost if:
a. The manual mode is exited,
b. The GOSQM <G039#7> (tool compensation amount
write mode select) signal becomes 0,
c. A contact detected signal is received from the touch
sensor, resulting in a tool compensation amount being
set or a alarm (PS5195) being issued,
d. The servo power becomes off (resulting in the stored
pulses for the related axis being lost), or
e. Axis movement occurs (resulting in the stored pulses for
the other axis being lost).
2 Axis interlock that has occurred for the axis direction
identified by parameter–based automatic decision and
two–axis, four–direction interlock that has occurred because of
a PS alarm being issued are canceled when the manual mode
is exited or the GOSQM <G039#7> (tool compensation mount
write mode select) signal becomes 0.
A reset does not cancel interlock.
・If the tool setter function for a one-turret/two-spindle lathe is used
Parameter No. 5053 is used to specify for which spindle (1 or 2) tool compensation numbers
(tool compensation amount memory) are to be used.
Example) If there are 32 tool compensation sets
