Blow-molding Module 27
Publication 1746-IN014B-EN-P - January 2001
G-file Configuration
The module requires software-configured selections in G file words 1-4 for axes
1-4, respectively. All four axes have identical structures:
Bit Purpose Selection
00
axis operation is time based
(1) (2)
(1) Bits 00 and 01 must be set to opposite states, else a fault occurs.
(2) When setting up a continuous extrusion machine, consider this:
Select time-based operation for each axis to be used.
Specify zero for the independent axis.
Select an SLC-generated or externally-generated start-of-drop synchronization input, depending
on your machine requirements.
Select SLC-generated or module-generated synchronization output, depending on your machine
requirements.
Specify a user profile size of 256 points
(unless SLC memory space requires fewer points)
0 = disabled, 1 = enabled
01 axis operation is position based (if set, see (3) )
(3) When setting up an accumulator machine, consider this:
Select position-based operation for each axis to be used.
Specify a number between 0 and 3 for each independent axis.
Select an SLC-generated start-of-drop synchronization input, since this feature is unused in
position-based mode (This lets the SLC processor use the input for other purposes).
Select SLC-generated or module-generated synchronization output, depending on your
application’s requirements.
Specify a profile size of 256 points
(unless SLC memory space requires fewer points)
0 = disabled, 1 = enabled
02-04 mandrel will follow:
- accumulator axis number:
- SLC profile via output image file:
enter bit code, such as
000 for axis 1, 001 for axis 2, 010
for axis 3, 011 for axis 4
100
05 axis synch input source (see note 3) 0 = from module DIN input
1 = from SLC output image
06 axis synch output source (see note 3) 0 = from module DOUT
1 = from SLC output image
07 SP and PV range 0=-32k to +32k
1= 0 to +10k
08-15 axis profile size (modulo 256) range of 0-255 (see
note 3) bit code for number of setpts
