Control Response
MP1 controls are available with optional control passage orifices to assist in matching the rate of
swashplate response to the application requirements. The time required for the pump output flow to
change from zero to full flow (acceleration) or full flow to zero (deceleration) is a net function of spool
porting, orifices, and charge pressure. A swashplate response table is available for each frame indicating
available swashplate response times. Testing should be conducted to verify the proper orifice selection
for the desired response.
