Mid-Move 1 and Mid-Move 2

These parameters are advanced dot parameters used for special applications and testing. For

more information, contact 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. See more information on Height Sensor in the dispensing system

Operations Manual. The units are inches/second. Typically, 2 in/sec is the default setting.

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/sec

is the default setting.

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.

On Vector Mode/Off Vector Mode

These parameters are advanced dot parameters used for special applications and testing. For

more information, contact Asymtek Application Engineering.

Number of Shots

This parameter controls how many shots of fluid will be dispensed at a single location. When

making larger dots, it is desirable to move the needle up between shots at the same location.

This parameter is set >1 for more than one dot at the same location, and the Multi-shot Delta

is the vertical retract distance of the needle between each shot. The units are in shots.

Typically, this is set to 1 unless you are dispensing as described above.

Multi-Shot Delta

This is the height that the dispensing head retracts between multiple shots at the same

location. It is used in conjunction with Number of Shots. The units are in inches. If using with

Number of Shots, a typical value is 0.010 inches.

Retract Speed

This is the speed of the dispensing head while moving the Retract Distance. This parameter

effects when the dispensing head moves to do the next line. The units are in inches/second.

Typically, 2 in/sec is sufficient.
