ADAP-KOOL Drive Operating Instructions
Function
Parameters used to program the fundamental functions of the frequency converter and the LCP including:
selection of language; selection of which variables are displayed at each position in the display (e.g. static
duct pressure or condenser water return temperature can be displayed with the setpoint in small digits in the
top row and feedback in large digits in the centre of the dispay); enabling/disabling of the LCP keys/buttons;
passwords for the LCP; upload and download of commissioned parameters to/from the LCP and setting the
built in clock.
Parameters used to configure the frequency converter for the specific application and motor including: open
or closed loop operation; type of application such as compressor, fan or centrifugal pump; motor nameplate
data; auto-tuning of the drive to the motor for optimum performance; flying start (typically used for fan
applications) and motor thermal protection.
Parameters used to configure braking functions of the frequency converter which although not common in
many ADAP-KOOL applications, can be useful on special fan applications. Parameters including: DC braking
and resistor braking.
Parameters used to program the minimum and maximum reference limits of speed (RPM/Hz) in open loop or
in actual units when operating in closed loop; digital/preset references; jog speed; definition of the source of
each reference (e.g. which analog input the reference signal is connected to); ramp up and down times and
digital potentiometer settings.
Parameters used to program limits and warnings of operation including: allowable motor direction; minimum
and maximum motor speeds ; torque and current limits to protect the pump, fan or compressor driven by the
motor; warnings for low/high current, speed, reference, and feedback; missing motor phase protection; speed
bypass frequencies including semi-automatic setup of these frequencies (e.g. to avoid resonance conditions
on cooling tower and other fans).
Parameters used to program the functions of all digital inputs, digital outputs, relay outputs, pulse inputs and
pulse outputs for terminals on the control card and all option cards.
Parameters used to program the functions associated with all analog inputs and analog outputs for the
terminals on the control card and General Purpose I/O option (MCB108) (note: NOT Analog I/O option
MCB109, see parameter group 26-**) including: analog input live zero timeout function (which for example
can be used to command a cooling tower fan to operate at full speed if the condenser water return sensor
fails); scaling of the analog input signals (for example to match the analog input to the mA and pressure
range of a static duct pressure sensor); filter time constant to filter out electrical noise on the analog signal
which can sometimes occur when long cables are installed; function and scaling of the analog outputs (for
example to provide an analog output representing motor current or kW to an analog input of a DDC
controller) and to configure the analog outputs to be controlled by the BMS via a high level interface (HLI)
(e.g. to control a chilled water valve) including ability to define a default value of these outputs in the event
of the HLI failing.
Parameters used for configuring and monitoring functions associated with the serial communications / high
level interface to the frequency converter
Parameters used to configure special functions of the frequency converter including: setting of the switching
frequency to reduce audible noise from the motor (sometimes required for fan applications); kinetic back-up
function (especially useful for critical applications in semi-conductor installations where performance under
mains dip/mains loss is important); mains imbalance protection; automatic reset (to avoid the need for a
manual reset of Alarms); energy optimisation parameters (which typically do not need changing but enable
fine tuning of this automatic function (if necessary) ensuring the frequency converter and motor combination
operate at their optimum efficiency at full and partial load conditions) and auto-derating functions (which
enable the frequency converter to continue operation at reduced performance under extreme operating
conditions ensuring maximum up time).
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.
Read only parameters which display the status/value of many operating variables which can be displayed on
the LCP or viewed in this parameter group. These parameters can be particularly useful during commissioning
when interfacing with a BMS via a high level interface.
Read only parameters which display the last 10 preventative 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.
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;
programming of the setpoint(s) and manual or auto-tuning of the PI(D) loop.
