[Function] Wait for the zone status of any of the axes (OR) specified by the axis pattern in operand 2
to become ON (inside zone) with respect to the zone specified in operand 1.
(Note 1) The zone command is a dedicated linear movement axis function. If this command is
specified for a SCARA axis, an “Error No. B80, Specification-prohibited axis error” will
generate.
(Note 2) The zone status for a given axis remains OFF (outside zone) until the axis completes home
return.
(Note 3) Four zone areas can be set for each axis (“Axis-specific parameter Nos. 86 to 97”).
(Note 4) Irrespective of this command, zone outputs can be specified using “Axis-specific parameter
Nos. 88, 91, 94 and 97.”
[Example 1] WZNO 1 110000 Wait until the zone status of axis 5 or 6 becomes ON
when the parameters are set as follows (= until either
axis enters the shaded range specified below).
[Example 2] An axis pattern can be indirectly specified using a variable. An example of specifying
the operation in [Example 1] indirectly using a variable is shown below.
110000 (binary) o 48 (decimal)
LET 5 48 Assign 48 to variable 5.
WZNO 1 *5
Axis 5 Axis 6
“Axis-specific parameter No. 86, Zone 1 MAX of linear
movement axis” (specified in units of 0.001 mm)
300000 200000
“Axis-specific parameter No. 87, Zone 1 MIN of linear
movement axis” (specified in units of 0.001 mm)
150000 100000
The program will proceed to the next step once
axes 5 and 6 are inside the shaded area.
Axis 6
