Q5-08
(0F27)
Suction Pressure
Control Minimum
Speed
Suction Min Spd
Sets the minimum speed at which the drive will run when the
drive is controlling suction pressure.
When the drive is controlling outlet pressure or this parameter
is set lower than P1-06 and P4-12, parameters P1-06 and P4-12
will be used as the minimum speed.
