PID is NOT disabled via digital input
Pre-Charge Level Set (P4-01 > 0) (and if used, P4-32 > 0)
Feedback is greater than Pre-Charge Level (P4-01) and Pre-charge Level 2 (P4-32) (forward-acting PID, b5-09 = 0) or less
than Pre-Charge Levels 1 and 2 (reverse-acting PID, b5-09 = 1)
Drive is NOT in a "Feedback Loss" condition (4 to 20 mA wire-break detection).

P4-10: AUTO Mode Operator Run Power Down Storage
Selects drive response to power loss with regards to the Run command. When running in AUTO Mode and using a Run
command from the keypad (b1-02 = 0), P4-10 determines whether the drive will automatically start running when power is
reapplied. The factory setting of this parameter requires pressing the AUTO key to start the drive after power loss.
WARNING! Sudden Movement Hazard. If the drive is running at power loss, it will automatically initiate an internal Run command upon
power-up if P4-10 = 1 (Enabled) and could result in death or serious injury from moving equipment.
No.

n P4-12: Thrust Bearing Frequency
Sets the frequency used by the drive when determining which acceleration and deceleration time to use. The Thrust Bearing
function is used for applications using submersible motors. The function provides an alternate acceleration time (P4-11) and
deceleration time (P4-13) for protecting the pump bearings.
At start, the drive will use the P4-11 acceleration time until the P4-12 frequency is reached, at which time it will use the active
C1-oo acceleration and deceleration times. At stop, if the output frequency is above the P4-12 setting, the active C1-oo
deceleration time will be used until the P4-12 setting is reached at which time it will use the P4-13 time setting for the rest of
deceleration.
If P4-12 is set greater than P1-06 (minimum Pump Speed), P4-12 will become the frequency lower limit. The drive PID control
must be disabled (b5-01 = 0) for this function to work.
No.
