4 POSITIONING SIGNALS
(8) Single block mode signal (M4408)
(a) This signal validates a single block valid in the mode which executes a
single block during execution of program.
(b) The single block processing (M4009) turns on by turning on the single block
mode.
(9) Single block start signal (M4409)
(a) This signal re-starts a single block in the mode which executes a single
block during execution of program.
(b) The single brock start is made valid by turning it from OFF to ON. However,
the single block start during axis travel is not accepeted.
(c) When the single block processing signal (M4409) and the single block mode
signal (M4408) are ON, making a single block start continues single block
operation.
(d) When the single block processing signal (M4409) is ON and the single
block mode signal (M4408) is OFF, making a single block start stops single
block operation and starts continuous operation. At this time, the single
block processing (M4409) turns off.
(10) Axis interlock valid/invalid (M4418)
This command is used to validate the axis interlock (forward)/(reverse).
• ON.......... Valid: If the axis interlock (forward)/(reverse) command turns
• OFF........ Invalid: Even if the axis interlock (forward)/(reverse) command
Defaut value is invalid (OFF).
