CAUTION:
Your controller’s hardware interface file (.hwi) includes
options to clamp the servovalve when a hydraulic
interlock occurs (these options cause the actuator to
stop, fully extend, or fully retract). However, if the
servovalve is imbalanced, it may move unexpectedly
when clamped.
Unexpected actuator movement can cause injury and
equipment damage.
Before enabling the valve clamp feature, ensure that the
servovalve is balanced.
Mode: Select Single to configure this card to drive a single servovalve;
select Dual to configure this card to drive dual servovalves. 2SVD Analog Output icon
Range: Enter the full-scale current value for the servovalve driven
by this card (100 mA maximum per output).
