9.3 Interrupt 1-speed Constant Quantity Feed
The interrupt 1-speed constant quantity feed function is also supported in Ver. 1.10 or later when the ring
operation is set for the current address.
(Refer to Subsection 9.3.2.)

9.3.1 Interrupt 1-speed Constant Quantity Feed
When the interrupt 1-speed constant quantity feed mode selection (BFM #519/#619 b6) is OFF, the 20SSC-H
positions the motor by the relative movement quantity set in the target address 1 after an interrupt input is
given.
(This function is same as the function available in versions earlier than Ver.1.10.)
1. Operation
1) Set the operation speed 1 and target address 1 (travel distance after interrupt input).
2) Select the interrupt 1-speed constant quantity feed from the operation patterns and activate the START
command to start the interrupt 1-speed constant quantity feed (above figure).
(The positioning completion signal is turned OFF.)
3) At interrupt input (INT0) ON, the work piece moves at the operation speed 1 to the target address 1,
where the operation ends and the positioning completion signal turns ON.
In a 20SSC-H Ver. 1.30 or later, the current address when an interrupt input (INT0) occurs is stored in the
"current address when an interrupt occurs (INT0)."
