7 How to Programme the Frequency Converter7.1 How to Programme7.1.1 Parameter Set-UpGroup Title Function0- Operation and Display 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. staticduct pressure or condenser water return temperature can be displayed with the setpoint in small digits in thetop 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 thebuilt in clock.1- Load / Motor Parameters used to configure the frequency converter for the specific application and motor including: openor closed loop operation; type of application such as compressor, fan or centrifugal pump; motor nameplatedata; auto-tuning of the drive to the motor for optimum performance; flying start (typically used for fanapplications) and motor thermal protection.2- Brakes Parameters used to configure braking functions of the frequency converter which although not common inmany ADAP-KOOL applications, can be useful on special fan applications. Parameters including: DC brakingand resistor braking.3- Reference / Ramps Parameters used to program the minimum and maximum reference limits of speed (RPM/Hz) in open loop orin actual units when operating in closed loop; digital/preset references; jog speed; definition of the source ofeach reference (e.g. which analog input the reference signal is connected to); ramp up and down times anddigital potentiometer settings.4- Limits / Warnings Parameters used to program limits and warnings of operation including: allowable motor direction; minimumand maximum motor speeds ; torque and current limits to protect the pump, fan or compressor driven by themotor; warnings for low/high current, speed, reference, and feedback; missing motor phase protection; speedbypass frequencies including semi-automatic setup of these frequencies (e.g. to avoid resonance conditionson cooling tower and other fans).5- Digital In / Out Parameters used to program the functions of all digital inputs, digital outputs, relay outputs, pulse inputs andpulse outputs for terminals on the control card and all option cards.6- Analog In / Out Parameters used to program the functions associated with all analog inputs and analog outputs for theterminals on the control card and General Purpose I/O option (MCB108) (note: NOT Analog I/O optionMCB109, see parameter group 26-**) including: analog input live zero timeout function (which for examplecan be used to command a cooling tower fan to operate at full speed if the condenser water return sensorfails); scaling of the analog input signals (for example to match the analog input to the mA and pressurerange of a static duct pressure sensor); filter time constant to filter out electrical noise on the analog signalwhich can sometimes occur when long cables are installed; function and scaling of the analog outputs (forexample to provide an analog output representing motor current or kW to an analog input of a DDCcontroller) 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 eventof the HLI failing.8- Communication and Options Parameters used for configuring and monitoring functions associated with the serial communications / highlevel interface to the frequency converter14- Special Functions Parameters used to configure special functions of the frequency converter including: setting of the switchingfrequency to reduce audible noise from the motor (sometimes required for fan applications); kinetic back-upfunction (especially useful for critical applications in semi-conductor installations where performance undermains dip/mains loss is important); mains imbalance protection; automatic reset (to avoid the need for amanual reset of Alarms); energy optimisation parameters (which typically do not need changing but enablefine tuning of this automatic function (if necessary) ensuring the frequency converter and motor combinationoperate at their optimum efficiency at full and partial load conditions) and auto-derating functions (whichenable the frequency converter to continue operation at reduced performance under extreme operatingconditions ensuring maximum up time).15- FC Information Parameters providing operating data and other drive information including: operating and running hourcounters; kWh counter; resetting of the running and kWh counters; alarm/fault log (where the past 10 alarmsare logged along with any associated value and time) and drive and option card indentification parameterssuch as code number and software version.16- Data Readouts Read only parameters which display the status/value of many operating variables which can be displayed onthe LCP or viewed in this parameter group. These parameters can be particularly useful during commissioningwhen interfacing with a BMS via a high level interface.18- Info & Readouts Read only parameters which display the last 10 preventative maintenance log items, actions and time and thevalue of analog inputs and outputs on the Analog I/O option card which can be particularly useful duringcommissioning when interfacing with a BMS via a high level interface.20- FC Closed Loop Parameters used to configure the closed loop PI(D) controller which controls the speed of the pump, fan orcompressor 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 apressure signal is used for indication of flow in an AHU or converting from pressure to temperature in acompressor 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 calculatethe 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.Table 7.1 Parameter GroupsHow to Programme the Frequ...
