Mooddee 00
Similar to cylinder operation with standard 4-way directional control valves, this simple operational mode allows
direction control of the HAS actuator with simple push, pull discrete inputs.
Direction is set by inputs X15-02 and X15-03, with speed in either direction set by V1 in keypad menu.
VV11 ((VVeelloocciittyy sseettttiinngg 11))
controls the pump speed at percentage rate of maximum rating of the size pump. This
speed is closed loop at the motor, and cylinder speed may vary based upon pump leakage rates at different
pressures. The control theory is similar

When True (High) drive will react to other discrete inputs. When False (Low) inputs are ignored. Useful for disabling
unwanted pushbutton operation.

When True (High) drive will spin the pump in a clockwise function. HAS Speed is set by percentage of maximum
setting V1 in key pad setup
The HAS orientation call out in the model code set the extend and retract direction. Orientations "A" &
"H"(reservoir on Cap end) CW rotation Extend Cylinder, "B" & "C" (Reservoir on Head end) CCW rotation extends the
cylinder.

When True (High) drive will spin the pump in a counterclockwise function. Same as CW command, cylinder will
operate in opposite direction.

When increasing speed setting from stop to V1 setting- acceleration or Ramp Rate (R1) is used to ramp from stop to
V1 setting. When decreasing speed setting, deceleration or Ramp Rate (R2) is used to ramp from current speed to
stopped condition. Default Ramp Rates are 300 mS. For Softer starts and Stops Ramp Rates can be increased
through keypad entry.
