Group Title Function
AO-## Analog I/O Option Parameters used to configure the Analog I/O option (OPCAIO) including: definition of the analog input types
(e.g. voltage, Pt1000 or Ni1000) and scaling and definition of the analog output functions and scaling.
DN-## CAN Fieldbus Parameters only applicable when a DeviceNet option is installed.
PB-## Profibus Parameters only applicable when a Profibus option is installed.
LN-## LonWorks Parameters only applicable when a Lonworks option is installed.
BN-## BACmet Parameters used for BACnet configuration.
ID-## Drive Information Parameters providing operating data and other drive information including: operating and running hour
counters; kWh counter; resetting of the running and kWh counters; alarm/fault log (where the past 10 alarms
are logged along with any associated value and time) and drive and option card indentification parameters
such as code number and software version.
DR-## Data Readouts Read only parameters which display the status/value of many operating variables which can be displayed on
the Keypad or viewed in this parameter group. These parameters can be particularly useful during commis-
sioning when interfacing with a BMS via a high level interface.
LG-## Logs & I/O Opt. Status Read only parameters which display the last 10 prevantative maintenance log items, actions and time and
the value of analog inputs and outputs on the Analog I/O option card which can be particularly useful during
commissioning when interfacing with a BMS via a high level interface.
AP-## HVAC Appl. Param. Parameters used to monitor, protect and control pumps, fans and compressors including: no flow detection
and protection of pumps (including auto-setup of this function); dry pump protection; end of curve detection
and protection of pumps; sleep mode (especially useful for cooling tower and booster pump sets); broken belt
detection (typically used for fan applications to detect no air flow instead of using a
∆p switch installed across
the fan); short cycle protection of compressors and pump flow compensation of setpoint (especially useful for
secondary chilled water pump applications where the
∆p sensor has been installed close to the pump and not
acoss the furthest most significant load(s) in the system; using this function can compensate for the sensor
installation and help to realise the maximum energy savings).
FB-## Fire/Bypass Operation Parameters used to set-up Fire Mode and/or to control a bypass contactor/starter if designed into the system.
T-## Timed Functions Time based parameters including: those used to initiate daily or weekly actions based on the built in real time
clock (e.g. change of setpoint for night set back mode or start/stop of the pump/fan/compressor start/stop of
a external equipment); preventative maintenance functions which can be based on running or operating hour
time intervals or on specific dates and times; energy log (especially useful in retrofit applications or where
information of the actual historical load (kW) on the pump/fan/compressor is of interest); trending (especially
useful in retrofit or other applications where there is an interest to log operating power, current, frequency or
speed of the pump/fan/compressor for analysis and a payback counter.
CL-## PID Closed Loop Parameters used to configure the closed loop PI(D) controller which controls the speed of the pump, fan or
compressor in closed loop mode including: defining where each of the 3 possible feedback signals come from
(e.g. which analog input or the BMS HLI); conversion factor for each of the feedback signals (e.g. where a
pressure signal is used for indication of flow in an AHU or converting from pressure to temperature in a
compressor application); engineering unit for the reference and feedback (e.g. Pa, kPa, m Wg, in Wg, bar, m3/
s, m3/h, °C, °F etc); the function (e.g. sum, difference, average, minimum or maximum) used to calculate the
resulting feedback for single zone applications or the control philosophy for multi-zone applications; pro-
gramming of the setpoint(s) and manual or auto-tuning of the PI(D) loop.
XC-## Ext. PID Closed Loop Parameters used to configure the 3 extended closed loop PI(D) controllers which for example can be used to
control external actuators (e.g. chilled water valve to maintain supply air temperature in a VAV system) in-
cluding: engineering unit for the reference and feedback of each controller (e.g. °C, °F etc); defining the range
of the reference/setpoint for each controller; defining where each of the references/setpoints and feedback
signals come from (e.g. which analog input or the BMS HLI); programming of the setpoint and manual or auto-
tuning of the each of the PI(D) controllers.
PC-## Pump Controller Parameters used to configure and monitor the built in pump cascade controller (typically used for pump
booster sets).
LC-## Logic Controller Parameters used to configure the built in Logic Controller (LC) which can be used for simple functions such as
comparators (e.g. if running above xHz, activate output relay), timers (e.g. when a start signal is applied, first
activate output relay to open supply air damper and wait x seconds before ramping up) or a more complex
sequence of user defined actions executed by the LC when the associated user defined event is evaluated as
TRUE by the LC. (For example, initiate an economiser mode in a simple AHU cooling application control scheme
where there is no BMS. For such an application the LC can monitor the outside air relative humidity and if it is
below a defined value, the supply air temperature setpoint could be automatically increased. With the fre-
quency converter monitoring the outside air relative humidity and supply air temperature via it’s analog inputs
and controlling the chilled water valve via one of the extended PI(D) loops and an analog output, it would then
modulate that valve to maintain a higher supply air temperature). The LC can often replace the need for other
external control equipment.
B-## Brakes Parameters used to configure braking functions of the frequency converter which although not common in
many AF-600 FP applications, can be useful on special fan applications. Parameters including: DC braking;
dymamic/resistor braking and over voltage control (which provides automatic adjustment of the deceleration
rate (auto-ramping) to avoid tripping when decelerating large inertia fans)
Parameter descriptions and selections are displayed on the keypad display. (See relevant section for details.) Access the parameters by pressing the [Quick
Menu] or [Main Menu] button on the keypad. The Quick Menu is used primarily for commissioning the unit at start-up by providing the parameters necessary to
start operation. The Main Menu provides access to all parameters for detailed application programming.
All digital input/output and analog input/output terminals are multifunctional. All terminals have factory default functions suitable for the majority of AF-600 FP
applications but if other special functions are required, they must be programmed as explained in parameter group E-## or AN-##.
