Sets the time at which the drive output frequency will ramp up
to the reference frequency set in P4-12.
Thrust Acc. Time
The drive will accelerate to this frequency in the time set to
P4-11. The drive will decelerate from the frequency in the time
set to P4-13.
Thrust Freq.
WARNING! Sudden Movement Hazard. If the drive is
powered down while running, it will automatically initiate
an internal Run command upon power-up.
Sets the amount of time it takes to bring the drive from the Thrust
Frequency set in P4-12 to stop when Thrust Mode is active.
When the Run command is removed while the drive is operating
Thrust Dec Time
in Thrust Mode above the Thrust Frequency, the time set in this
parameter is used when the frequency reference is at or below
the thrust frequency.
2Motor Alternate Enables and disables the alternation feature

switches to the other motor.
Sets the amount of time that the drive will delay starting if a Run
command is present at power-up.
When P1-01, Pump Mode, is set to 3 (MEMOBUS network),
Utility Delay
the drive is unavailable to the network (Pump Off Network)
when the function is active.
Setting this parameter to 0.0 disables the function.
Sets the maximum difference allowed between the PID
Feedback and the Differential Feedback.
Differential Lvl The drive will respond based on the setting in P4-20 when the
difference exceeds the value set in this parameter for the time
set in P4-19.
Sets the amount of time that the difference between PID
Diff Lvl DetTime Feedback and the Differential Feedback must exceed the P4-18
value before responding based on the P4-20 value.
