FANUC Series 30i-MODEL A
Improvement of stored stroke limit 1
2.3.2 Stored Stroke Check 1
Overview
A machine movable range is set with coordinates in the machine coordinate
system in parameters. If the machine attempts to move beyond the range, it
is decelerated and stopped and an alarm is displayed. This function is
enabled after manual reference position return is performed after power-on.
It can be used instead of an overtravel limit switch (hardware component).
When both functions are used, both are valid. Unlike an overtravel limit
switch, this function checks whether the position at which the machine is
stopped after decelerated from the current position is beyond the range. The
stroke check 1 release signal common to all axes can be set to 1 so that the
control unit does not make stroke check 1.
Explanation
Parameters (Nos. 1320, 1321 or Nos. 1326, 1327) set boundary. Outside the
area of the set limits is a forbidden area. The machine tool builder usually
sets this area as the maximum stroke. When the tool enters a forbidden area
and an alarm is generated, the tool can be moved in the reverse direction
from which the tool came.
In this time, the “Stroke limit reached signals” can be outputted by the
setting of the parameter OTS (No.1301 bit 6)=1. And, when the parameter
NAL (No.1300 bit 1) is set to “1”, in case of manual operation, when the
axis is entered to the forbidden area, the alarm is not generated, and only the
Stroke limit reached signals can be outputted to the PMC. In this case, the
alarm is generated during automatic operation.
Signal
Stored stroke check 1 select signal EXLM<Gn007#6>
[Classification] Input signal
[Function] Selects stroke check 1-I (parameter Nos. 1320 and 1321) or stroke check
1-II(parameter Nos. 1326 and 1327).
[Operation] When this signal is set to 1, checks stroke check 1 on the basis of
parameter Nos. 1326 and 1327,instead of parameter Nos. 1320 and 1321.
The parameter values are used for all axes. If the bit 2 (LMS) of parameter
No.1300 is set to 1, this signal is enabled.
