[Function] The axes in the axis pattern specified in operand 1 will move forward or backward while the
input or output port or flag specified in operand 2 is ON or OFF.
JBWF Move backward while the specified port is OFF.
JBWN Move backward while the specified port is ON.
JFWF Move forward while the specified port is OFF.
JFWN Move forward while the specified port is ON.
(Note 1) This command is also valid on an axis not yet completing home return. In this case, the
maximum speed will be limited by “All-axis parameter No. 15, Maximum jog speed before
home return.” Since coordinate values do not mean anything before home return, pay due
attention to prevent contact with the stroke ends.
[Example 1] VEL 100 Set the speed to 100 mm/s.
JBWF 11 10 Move axes 1 and 2 backward while input 10 is OFF.
[Example 2] The axis pattern can be specified indirectly using a variable.
When the command in [Example 1] is rephrased based on indirect specification using a
variable:
11 (binary)
o
3 (decimal)
VEL 100 Set the speed to 100 mm/s.
LET 1 3 Assign 3 to variable 1.
JBWF *1 10
[Example 3] VEL 100 Set the speed to 100 mm/s.
LET 5 20 Assign 20 to variable 5.
JFWN 10 *5 Move axis 2 forward while the content of variable 5 (input
20), is ON.
