Blow-molding Module 43
Publication 1746-IN014B-EN-P - January 2001
Descriptions of module parameters
Module Parameter Description
axis control structure 64 axis-configuration words that you enter in the M0 file
axis current adc input raw 14-bit value read from adc (for LVDT position counts)
axis current control output 16-bit integer
axis current dac output raw 14-bit value written to dac
axis current process variable 16-bit integer representing the position input
axis current profile step indicates which step of a profile is currently executing
axis current setpoint indicates axis target position (can be unrelated to the profile)
axis full-scale point calibrated maximum travel limit of LVDT
axis zero-scale point calibrated minimum travel limit of LVDT
axis process-variable profile 256 words in M1 file to indicate actual setpoint execution
axis setpoint profile 256 words in M0 file to control parison head or accumulator
axis synchronization input command trigger to start drop of the parison
axis synchronization output signal used to synchronize external hardware with a profile step
interpolated setpoint profile returned master profile filled with module-computed setpoints.
master setpoint profile selected critical profile setpoints in M0 file. Other setpoints = 0
operation: position-based mode profile steps triggered by position inputs from LVDT
operation: time-based mode profile steps triggered by module-computed time intervals
parison weight adjustment capability to offset entire profile to adjust weight of parison-
profile scale adjustment capability to change profile scale without changing part weight
setpoint marking capability to relate a setpoint in the profile to a ridge in the part
shotsize length of screw backup to inject a full shot of melt
signed-integer format minimum value of -32768 corresponds to zero-scale (fully-closed or
fully-forward) and the maximum value of +32767 corresponds to full-scale
(fully-open or fully-retracted).
