Group Title Function
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 acceling) 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 frequency 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 and over voltage control (which provides automatic adjustment of the
deceleration rate (auto-ramping) to avoid tripping when decelerating large inertia fans)
Table 6.1 Parameter Groups
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-##.
