6.5.1 Pre-Dispense Dot Parameters
Item Description
Settling Time
This is the length of time that the dispensing head will park over the
dispensing location before beginning to dispense. The Settling Time is
set to 0, except in special circumstances. For more information, contact
Nordson ASYMTEK Application Engineering.
Down Speed
The Down Speed is how fast the dispensing head lowers to dispense.
Low viscosity fluids tend to drip and you may want to set this parameter
to a high value. The higher the value, the faster the dispensing head will
move. Height sense accuracy is dependent on Down Speed and Down
Acceleration. The units are inches/second. Typically, 2 in/sec is the
default setting. Refer to the manual for your particular dispensing system
for information on your height sensor.
Down Acceleration
This parameter controls how fast the dispensing head accelerates to the
Down Speed. The higher the value, the faster the dispensing head will
move. The units are in inches/second squared. Typically, 300 in/sec2 is
the default setting.
