3 (Run at b5-13).
Detects loss of prime in the pump when a wire break condition
has occurred.
When the measured quantity determined by P1-18 (output
current, kilowatts, or power) drops below this level for the time

set in P1-20 and the output frequency is at the level set in b5-13,
a "Loss of Prime" condition occurs.
The drive responds to the "Loss of Prime" condition depending
on the setting of P1-22, Loss of Prime Selection.
Sets the acceleration and deceleration time to PID setpoint.
Sets the minimum output possible from the PID controller as a
percentage of the maximum output frequency.
Limits the PID control input (deviation signal) as a percentage
of the maximum output frequency. Acts as a bipolar limit.
