Before operation can be performed based on the electronic cam function
(electronic cam operation), phase matching is required. Phase matching
is the function for matching the phase relationship between the cam shaft
and a tracing axis by moving the tracing axis to the tracing axis position
corresponding to the cam shaft phase at an electronic cam operation start
position.
G140 _;IP
IP_: Specify a tracing axis for which phase matching is to be per-
formed. After a tracing axis name, specify 0.
Move the cam shaft to an electronic cam operation start position. A start
position other than phase 0 may be selected. When the program is
executed, a specified tracing axis moves at a rapid traverse rate (parameter
No. 1420) to the tracing axis position corresponding to the phase of the
cam shaft. At this time, a rapid traverse override and rapid traverse
acceleration/deceleration (linear or bell–shaped) are usable. When phase
matching is completed, the phase matching completion signal ECMCP*
(F223) is set to 1. When the electronic cam function end signal
ECMEND* (G239#1) is switched from 0 to 1 during phase matching,
phase matching is stopped. If the cam shaft or tracing axis moves
independently after completion of phase matching, the phase matching
completion signal ECMCP* (F223) is set to 0.
Example:
When performing phase matching for tracing axes 1, 2, 3,
and 4 (with the axis names X, Y, Z, and A, respectively),
specify the following:
G140 X0 Y0 Z0 A0;
WARNING
During phase matching, interlock (high speed, all axes,
each axis, axis direction) is disabled for a tracing axis.
NOTE
1 Before performing phase matching, be sure to store cam
figure data. If phase matching is performed without storing
cam figure data, alarm No. 5249 is issued.
2 Set the cam shaft and tracing axes with parameter No. 8086
and No. 8087.
3 During phase matching, be sure to stop the cam shaft.
4 Phase matching can also be performed with an input signal.
