Description of I/O Signals
2
Interrupt input enable: Sequence input signal (Reference value 48)
Interrupt input: Sequence input signal (Reference value 49)
Use to realize the interrupt positioning function.
These functions are enabled only if "6" (extension mode) or "7" (positioning operation) is selected for
parameter PA1_01.
These functions are enabled with the forward command [FWD] / reverse command [REV], positioning
data operation, and immediate value operation.
 Function
If the interrupt input enable signal assigned to a CONT input signal is turned on, stoppage is
caused after a travel of a certain amount since the interrupt input signal is turned on.
Specify the traveling amount after the interrupt input in PA2_20 (interrupt traveling unit amount).
The rotation speed after an interrupt input keeps the speed at the rising edge effective.
The override is enabled even after the rising edge.
To change the rotation speed in the interrupt positioning mode, use the override.
 Parameter setting
To assign interrupt input enable to a sequence input terminal, specify the corresponding value
("48") to the input terminal function setting parameter. For the interrupt input, specify ("49").
 Relevant description
(1) Operation procedure
The operation is started with the FWD command or REV command. After the interrupt input enable
is turned to ON, the interrupt positioning is executed to stop when the interrupt signal is turned to
ON.
