Intermediate Speed. The Run Intermediate field determines the percentage of maximum RPM a
secondary motor/pump will run at while operating in the Intermediate Speed mode.
Run Max
All Hawk motors/pumps have the ability to operate in two speed modes. A faster speed for large position
changes and a slower speed for fine-positioning. The faster, large position change speed is referred to as
the Max Speed. The Run Max field determines the percentage of maximum RPM a secondary
motor/pump will run at while operating in the Max Speed mode.
Max Start
The Max Start setting determines the interaction between the Intermediate Speed and the Max Speed.
If the deviation between the current position and the desired position is less than the Max Start setting
the secondary motor/pump will run at the Intermediate Speed. If the deviation between the current
position and the desired position exceeds the Max Start setting the secondary motor/pump will initially
run at the Max Speed, but once the deviation drops below the Max Start setting the secondary
motor/pump speed will switch from the Max Speed to the Intermediate Speed.
For example, if the Max Start field was set to 3 mA, the actuator was at the 12 mA position, and an 18 mA
command signal was applied, the secondary motor/pump would run at the Max Speed until the 15 mA
position and would then switch to the Intermediate Speed for the final 3 mA of travel. Conversely, if the
Max Start field was set to 3 mA, the actuator was at the 12 mA position, and a 14 mA command signal
was applied, the secondary motor/pump would only run at the Intermediate Speed until it reached the 14
mA position.
Delay Stop
The Delay Stop field determines the amount of time, in milliseconds, that the secondary motor/pump will
continue running after the HPS solenoids are closed. It is recommended that the delay be set to 0
milliseconds.
Operate in Manual
The Operate in Manual field allows the secondary motor/pump to be disabled while the HMI is operated
in Manual mode.
