Description
AP2-38 Dec
Valve Freq
Sets the start frequency where the slow deceleration begins in order to
prevent pump damage when the inverter stops. Decelerating valve ramping
is performed from the frequency set at AP2-38 to the frequency limit set at
ADV-25 (low frequency limit for pump operation).
AP2-39
DecValve Time
Sets the time it takes to decelerate from the frequency set at AP2-38 to the
frequency limit set at ADV-25 (low frequency limit for pump operation).
The time set at AP2-39 refers to the absolute time that it takes for the pump to decelerate
from the frequency set at AP2-38 to the frequency limit set at ADV-25.
