6Configure the VFD — All configurations required bythe VFD are supplied by the ICVC through the VFD Gateway.Any configuration changes necessary and possible are made onthe ICVC screens. A complete set of configurations is transmit-ted to the VFD each time the controls are powered up.The following is from the 19XRV PIC III ICVC screen. Pa-rameters in italics are to be entered or confirmed at start-up. Pa-rameters in bold are to be changed only after consulting withCarrier service engineering. See Table 2.Table 2 — VFD Configurations* Parameters marked with an * are not downloadable to the VFD but are usedin other calculations and algorithms in the ICVC.NOTES:1. Parameters in italics are to be entered or confirmed at start-up.2. Parameters in bold are to be changed only after consultation with ser-vice engineering.Commissioning the Unit — The commission proce-dure is as follows:1. If the chiller has been stored outdoors, allow at least 24hours room temperature stabilization prior to commis-sioning. Ensure any condensation that occurs as a resultof the ambient temperature is allowed to evaporate.2. Enter parameters in the VFD_CONF screen.3. Install surge suppression devices if required.4. Review the power wiring and grounding to ensure that ithas been properly connected.5. Visually examine the inside of the drive enclosure to:a. Look for signs of corrosion or moisture residue.b. Remove any dirt or debris.c. Make sure all vents are clear.6. Apply power to the drive and take thermal measurementsof the capacitor bank and power connections. Do thisagain before start-up.7. Measure and record the incoming line voltage. Line-to-line voltages should be balanced within 3% as calculatedby Rockwell’s procedure below:Measure voltages phase-to-phase and phase-to-ground.MODEL NUMBERSERIAL NUMBERVOLTS/PHASE/HERTZLOCKED ROTOR AMPSOVERLOAD TRIP AMPSMAX FUSE/CIRCUIT BREAKER SIZEMIN SUPPLY CIRCUIT AMPACITYMOTOR NAMEPLATE VOLTAGECOMPRESSOR 100% SPEEDRATED LINE VOLTAGERATED LINE AMPSRATED LINE KILOWATTSMOTOR RATED LOAD KWMOTOR RATED LOAD AMPSMOTOR NAMEPLATE AMPSMOTOR NAMEPLATE RPMMOTOR NAMEPLATE KWINTERTER PWM FREQUENCYMACHINE NAMEPLATE SUPPLY DATAMACHINE ELECTRICAL DATASAFETY CODE CERTIFICATIONTHE COMPRESSOR MOTOR CONTROLLER AND OVERLOAD PROTECTION MUST BEIN ACCORDANCE WITH CARRIER SPECIFICATION Z-420.19XV05008701 REV. 3A United Technologies CompanyFig. 8 — Machine Nameplatea19-1846Fig. 9 — Drive Module Labela19-1924PARAMETER DEFAULT VALUEMotor Nameplate Voltage 460Compressor 100% SpeedLine Freq=60 Hz?
