[Function] Wait for the zone statuses of all axes (AND) specified by the axis pattern in operand 2 to
become OFF (outside 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] WZFA 1 110000 Wait until the zone statuses of axes 5 and 6 become
OFF when the parameters are set as follows (= until
both axes enter 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.
WZFA 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
