Interrupt Feeding
Section 9-5
9-5 Interrupt Feeding
9-5-1 Overview
The PCU's interrupt feeding is a positioning operation that moves the axis for
a specified amount, separate from the position command value, from the posi-
tion at which the external interrupt signal was input either in the same direc-
tion as the direction of travel or in the opposite direction. The specified amount
of travel is performed at the speed being used when the external interrupt sig-
nal was input.
When an interrupt input signal is not input, positioning is performed to the tar-
get position specified in the position command value, as normal.
9-5-2 Interrupt Feeding Procedure
The interrupt feeding function is a supplementary function for positioning
operations using direct operation (ABSOLUTE MOVEMENT, RELATIVE
MOVEMENT). Interrupt feeding can be executed using the same procedure
as for direct operation by simply specifying interrupt feeding at the start of
direct operation.
The following procedure omits the steps up to SERVO LOCK, showing the
start procedure only.
1,2,3... 1. Transfer the Servo Parameters for interrupt feeding.
To set parameters permanently, execute SAVE SERVO PARAMETER
(writes to the non-volatile memory).
2. Set the data used for direct operation.
Set the positioning data for direct operation in the position command value
of the Axis Operating Output Memory Area.
Set the speed data for direct operation in the speed command value of the
Axis Operating Output Memory Area.
3. Turn ON the INTERRUPT FEEDING Bit.
4. Start ABSOLUTE MOVEMENT or RELATIVE MOVEMENT.
