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.

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.

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.

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.

When used in the Pump Control Application this feature is used to detect high load low load indicating blockage and low load indicating leakage.
PNO
Parameter Descriptions
1968 Enable Load Monitor
Set TRUE to enable this feature.
1969 Startup Delay
This sets the duration from when the motor is started until the load monitoring is started. This allows for inaccurate speed/load
characterisation and load estimation during start-up period.
1970 Fault Delay
This sets the duration from when the load monitor detects a LOAD FAULT until the sequencers stops the motor. This allows for
inaccurate speed/load characterisation and load estimation during start-up period.
1971 High Fault Level
This specifies the deviation of the actual load above the expected load which will cause a LOAD HIGH FAULT to be reported.
1972 High Warning Level
This specifies the deviation of the actual load above the expected load which will cause a LOAD HIGH WARNING to be reported.
1973 Low Warning Level
This specifies the deviation of the actual load below the expected load which will cause a LOAD LOW WARNING to be reported.
1974 Low Fault Level
This specifies the deviation of the actual load below the expected load which will cause a LOAD LOW FAULT to be reported.

This diagnostic reports whether the monitor is monitoring and, if so, if the Load is as expected. This is an enumerated value:
0 MONITORING DISABLED Either
Enable Load Monitor
is FALSE or
Speed 1
= 0.0%.
1 MONITORING STOPPED Motor not running, so not monitoring.
2 MONITORING STARTING Motor started less than
Startup Delay
ago, so not monitoring yet.
3 LOAD NORMAL The actual Load is within the expected range, so anomaly detected.
4 LOAD HIGH WARNING The actual Load is above the
High Warning Level
but not higher than the
High Fault Level
.
5 LOAD LOW WARNING The actual Load is below the Low Warning Level but not lower than the Low Fault Level.
6 LOAD HIGH FAULT The actual Load is above the
High Fault Level.
7 LOAD LOW FAULT The actual Load is below the Low Fault Level.
1998 Expected Load*
This diagnostic is the calculated Load expected for the current Speed. This is determined from the load ‘curve’ specified by the Speed
n and Load n parameters and is useful for checking that in the case of incorrect warning or fault reporting.
1999 Load Error*
This diagnostic is difference between
Actual Load
and
Expected Load
.

Pump Control (US units) Application Manual 13
AC30V series Variable Speed Drive
Functional Description
An estimate of the expected Load for any given Speed is specified using the Speed n and Load n parameters. Each pair provide a point on the
expected Load line.
The Speed parameters must have increasing values. I.e. Speed 1 < Speed 2 < Speed 3 < Speed 4 < Speed 5 < Speed 6 < Speed 7 < Speed 8
< Speed 9 < Speed 10.
If not all points are required, a Speed may be set to zero to terminate the sequence. If the actual speed is greater than the last specified point, the
line is extrapolated from the previous 2 points.
Speed 1 must be non-zero, otherwise the abnormal load detection feature is disabled.

Low Warning Level

High Warning Level
High Fault Level
Offset from the expected Load line, 4 additional lines are calculated. These are the Warning and Fault detection thresholds. The deviation from
normal behavior is determined by the High Fault Level ,High Warning Level,Low Warning Level and Low Fault Level parameters.
When running, the Load Monitor State diagnostic will show if the actual Load is in the NORMAL, WARNING or FAULT regions of the graph.
Note – for this to report correctly, the High Fault Level must be more positive than the High Warning Level and the Low Fault Level must be
more negative than the Low Warning Level.
If the actual Load remains in a FAULT region for longer than the duration specified by Fault Delay, the Drive will stop running.
The Start Delay may be used to prevent incorrect warning or fault reports soon after the Run command is issued.
The Load Monitor State diagnostic is reset when the Run command is removed.

Disable Coast Stop:
This feature disables the use of the COAST STOP input.
Caution The Drive will not stop when the coast stop input is disconnected.
