Run Min/Max
Sets the faster, large position change speed.
Jog Speed
Sets the actuator speed used for Manual and Setup mode operations.
Not in Position Alarm Time
The Hawk actuator controls monitor the duration of time needed for the actuator to move to a new
position after receiving a control signal. If the actuator is unable to reach the new position the
motor/pump are de-energized to prevent damage to the actuator or driven device. The duration of time
before the controls fault and send an alarm is defined by the Not in Position Alarm Time setting.
4-2.1 Multiple Motor/Pump Speed & Response Tuning
For Hawk units that are configured with more than one motor/pump
the speed and response tuning can
be configured by the user within the Setup menu for each individual motor/pump.
Start
For small actuator movements typically only a single motor/pump is used to reposition the actuator, and
the secondary motors/pumps are only activated for larger movements. The Start setting determines the
minimum deviation required between the current position and the desired position point to activate the
secondary motor/pump. For example, if the Start field was set to 2.0 mA and the actuator was at the 12
mA position the secondary motor/pump would be activated if a command signal of 14.1 mA was applied,
but it would not be activated with a command signal of 13.9 mA.
Stop
To prevent overshoot, typically secondary motors and pumps are deactivated at the end of travel and only
a single motor/pump is used for final positioning. The Stop setting determines the point at which a
secondary motor/pump is deactivated and is defined as a deviation between the current position and the
desired position. For example, if the Stop field was set to 1.0 mA and the actuator was moving towards a
desired position of 20 mA, the secondary motor/pump would be deactivated when the actuator position
reached 19 mA.
Run Intermediate
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 slower, fine-positioning speed is referred to as the
