PUMP SETTINGS

Acceleration
Set the Acceleration setting to the rate at which the output frequency will increase during normal operation.
This rate is based on the time the VFD would take to accelerate from 0 Hz to 60 Hz. Example: If the pump is
required to accelerate from 30 Hz to 60 Hz in 1.5 seconds the Acceleration rate should be set to 3 seconds.
Deceleration
Set the Deceleration setting to the rate at which the output frequency will decrease during normal operation.
This rate is based on the time the VFD would take to decelerate from 60 Hz to 0 Hz. Example: If the pump is
required to decelerate from 60 Hz to 30Hz in 1.5 seconds the Deceleration rate should be set to 3 seconds.
Thrust Bearing Frequency
The Thrust Bearing Frequency should be set to the frequency at which the initial acceleration rate changes
to the acceleration rate of normal operation. This is typically used on submersible type pumps, where the
manufacturer requires a faster acceleration rate from a stop to the Thrust Bearing Frequency for proper thrust
bearing operation. Set to 0.0 to disable the thrust bearing function. Note: If the Pipe Fill function is used at a
lower frequency, it will take precedence over the thrust bearing function.
Thrust Bearing Acceleration
Set the Thrust Bearing Acceleration to the rate at which the pump should accelerate from a stop to the Thrust
Bearing Frequency. This is typically used on submersible type pumps, where the manufacturer requires a
faster acceleration rate for proper thrust bearing operation.
Pump 1~3 Overload Amps
The Pump 1~3 Overload Amps setting should be set to the full load amp rating of the pump for non-
submersible applications and to the service factor amps for submersible pumps.
Pump 1~3 Motor Voltage
The Pump 1~3 Motor Voltage setting should be set to the voltage on the nameplate of the pump. This setting
cannot exceed the incoming voltage measured at the control panel input power terminals.
