Simplified Program Setup - JUKI AMS-221EN Series Engineer's Manual

(5) Simplified program setup

This machine is provided with the simplified program functions, which can make the programming of various addi-
tional devices (stacker, unit, etc.) according to sewing machine operation. In conjunction with the port I/O output
functions, modification into such additional devices can be carried out in the main unit of the sewing machine.
1. Specifications
(1) Operation by a maximum of five programs is possible.
(2) Inputs of a maximum of 99 steps can be entered per program.
(3) Interactive operation is possible among the five programs.
2. Setting items
The simplified program specifies the following five items per step.

The virtual I/O port is provided for an interface to be used for sewing machine control and simplified program control.
In the case of port I/O setup, either an input or output is set up as seen from the sewing machine control side.
(Caution) The virtual I/O port is an internal signal of the sewing machine. It cannot be brought out directly
to the outside.
3. Control operation
At the start of simplified program execution, operation is sequentially carried out starting from Step No. = 1, at the
intervals of 1ms for each step.
At the beginning of step execution, the con-
tents of output information setup are gen-
erated. Operation is suspended (with the
execution step No.) until the setup condi-
2
tions for the input information or Param-
eter have been established. When these
conditions are established, operation is for-
warded to the next step No. or the skip
1
destination step No. defined by Parameter
. Such a sequential operation is repeated
till the completion command.
(Caution)
In the simplified program control, the I/
O terminals and others are directly con-
trolled based on the output and input
information, irrespective of the result of
port I/O setup.
In particular, the output data are imme-
diately generated at the beginning of
step execution for the output terminals
and virtual I/O ports. In regard to I/O
mismatching and synchronization for
sewing machine control, therefore, pro-
grams have to be established carefully
on the side of simplified program.

terminals and 16 virtual I/O ports.
Multiple input conditions are set up for High and Low of the respective 16 output termi-
nals, 16 input terminals, 16 virtual I/O ports, and 6 operation switches.
Skip destination step No. or program No. is set up.
The input conditions of delay time, No. of stitches, No. of repetition times, etc. are set
up.
