11-3 Interrupt jog feed
The following describes the various data and operations when interrupt jog feed is performed.
To use the interrupt jog feed function, be sure to set parameter 1 (address A+0076 bits 0 to 3) to "1".
• Operation mode setting of general-purpose input (parameter 1 - address 0076 bits 0 to 3)
[1] Outline of function
The "interrupt jog feed" function moves the axis started up by speed control in the same direction as
the advance direction by a specified travel distance to perform positioning when the external input
interrupt input signal (CN2/3 pins 8 and 20) are input.
There are two startup modes, startup from program operation and startup from direct operation.
(Note) When there is inversion according to the interrupt input signal of travel in the direction
opposite to the advance direction, there is no acceleration or deceleration.
[2] Startup from program operation
With program operation, after the operation pattern in the step data is set to "3: speed control," this
step No. is started up and program execution waits for the interrupt input signal.
(1) Description at program operation
The general-purpose input signal functions as an external interrupt signal after the operation
pattern=3 (speed control) step is executed.
The travel distance after an interrupt detection is the value of the position data set in the step data
of the target step No., and axes move by that value and then come to a stop.
The speed and acceleration/deceleration time after an interrupt detection (when the speed is
changed or at a final stop) follows the step data of the target step No.
• The travel direction after an interrupt is generated is the same direction as the operation
direction.
• The present value at speed control operation and when an interrupt is generated follows the
parameter (6: present value at speed control operation) setting.
(Note) Speed control operation can be stopped only by "external interrupt" and "deceleration
stop."
