2 Pump Control (US units) Application Manual

AC30V series Variable Speed Drive

Pump Control (US units) Application Manual

Description

The pump application provides either flow control or speed control of a water pump.

In AUTO mode a flow feedback transducer is used to close the loop using a PID trim.

In MANUAL mode the requested pump speed is derived directly from the flow setpoint.

The calculated load is used to detect abnormal behaviour indicating blockage or leakage.

Feedback break input detection (4..20mA only).

Features

•Pump application specific menus and parameters

•Flow parameters and diagnostics in US Gallons / minute

•Pump Displacement in Cubic Inches

•PID flow control

•Automatic pump blockage and leakage detection (abnormal load)

•Power-up start

Requirements

To use the AC30V for pump control with US units as described in this manual, the application RA502134U005 must be loaded into an AC30V

series drive with firmware 1.4.1. or newer.

Setup::Application::Pump and Flow

Monitor::Application::Pump and Flow*

Application specific parameters to setup and monitor the pump and flow. All flow parameters are in Litres per minute (L/min).

PNO

Parameter Descriptions

1940Pump Speed Max

This is the maximum speed in RPM that the pump can operate. It is the same as the 0464:100% Speed in RPM parameter.

1941Pump Speed Min

This is the minimum speed in RPM that the pump is allowed to operate. It sets the low limit for the speed demand when running.

1942Pump Disp per Rev

This parameter sets the number of cubic inches (in3) displaced by one revolution of the pump. It is used to convert setpoints and

feedbacks given in US gallons per minute (GPM) to a pump speed in RPM.

1943Flow FB Input Max

This is the full range value in US Gallons / minute (GPM) in for the Flow Feedback analogue input (ANIN01). It corresponds to the

maximum input value of either 10V or 20mA depending on the setting of 0001: Anin 01 Type.

1944Flow FB Input Min

This is the minimum value in US Gallons / minute (GPM) for the Flow Feedback analogue input (ANIN01). It corresponds to the

minimum input value of either 0V, 0mA or 4mA depending on the setting of 0001: Anin 01 Type.

1945Flow SP Input Max

This is the full range value in US Gallons / minute (GPM) for the Flow Setpoint analogue input (ANIN02). It corresponds to the

maximum input value of 10V.

1946Flow SP Input Min

This is the minimum value in US Gallons / minute (GPM) for the Flow Setpoint analogue input (ANIN02). It corresponds to the

minimum input value of 0V.

1947Flow Setpoint Max

This is the maximum Flow Setpoint that can be set using the GKP, terminals or fieldbus.

1948 Flow Setpoint Min

This is the minimum Flow Setpoint that can be set using the GKP, terminals or fieldbus.

1949 Flow Local Setpoint

This is the Local Setpoint in US Gallons / minute (GPM) settable using the GKP. It is limited to be between 1947: Flow Setpoint Max

and 1948: Flow Setpoint Min, converted to a percentage of the flow rate at 0140: Pump Speed Max and then used to set the 0592:

Parameter Descriptions

Local Reference parameter.

1950 Flow Comms Setpoint*

This is the value of the remote terminal flow setpoint. It is clamped to be between 1947:Flow Setpoint Max and 1948:Flow Setpoint

Min

1951 Flow Setpoint*

This diagnostic is the value of the active flow setpoint. This will be the same as one of the following:

1953:Flow Remote Setpoint when in remote (terminal) control mode

1950:Flow Comms Setpoint when in comms control mode

1949: Flow Local Setpoint when in local control mode

1952 Flow Feedback*

This diagnostic is the value of the flow feedback in L/min. It is ANIN1 scaled and offset by 1943: Flow FB Input Max and 1944: Flow FB

Input Min.

1953 Flow Remote Setpoint*

This diagnostic is the value of the remote terminal flow setpoint. It is ANIN2 scaled and offset by 1945: Flow SP Input Max and 1946:

Flow SP Input Min, then clamped to be between 1947: Flow Setpoint Max and 1948:Flow Setpoint Min.

1954 Pump Demand*

This diagnostic is the requested speed of the pump as a percentage of 1940: Pump Speed Max. It is the same as 0500: Ramp Speed

Output.

1955 Actual load*

This diagnostic is the estimated load as a percentage of the maximum load. It is the same as the 0399: Actual Torque parameter

which is the calculated torque based on the IQ current.

Functional Description

The maximum pump speed is set in RPM using the 1940: Pump Speed Max parameter. This corresponds to 100% speed demand. A minimum

speed may be set using the 1940: Pump Speed Min parameter, also in RPM.

The calculation from flow the pump speed is set by the 1942:Pump Disp per Rev parameter.

The analog input used for the flow setpoint is scaled using the 1945: Flow SP Input Max and 1946: Flow SP Input Min parameters. These define

the range and offset in L/min. Similarly, the analog input used for the flow feedback is scaled using the 1947: Flow FB Input Max and 1948: Flow

FB Input Min parameters.

If not in flow control, the setpoint from either the GKP (1949: Flow Local Setpoint) or the communications (1950: Flow Comms Setpoint) may be

used instead of the setpoint from the terminals.
