Operand 1
Operand 2
Output
(Output, flag)
Optional Optional WZNO Zone
number
Axis
pattern
CP
[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)
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.

CP
[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.

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.
