Reinstall jumper afterconfiguration is complete.DIP switch settings:DIP switch 1 is not used.DIP switch 2 is the motor frequency. (OFF = 50 Hz,ON = 60 Hz)Drive Programming — Parameter values can be altered viathe operator panel. The operator panel features a five-digit,seven-segment display for displaying parameter numbers andvalues, alarm and fault messages, set points, and actual values.See Fig. 14 and 15. See Table 20 for additional information onthe operator panel.NOTE: The operator panel motor control functions are disabledby default. To control the motor via the operator panel,parameter P0700 should be set to 1 and P1000 set to 1. Theoperator panel can be fitted to and removed from the drivewhile power is applied. If the operator panel has been set as theI/O control (P0700 = 1), the drive will stop if the operatorpanel is removed.Changing Parameters with the Operator Panel — See Fig. 15for the procedure for changing the value of parameter P0004.Modifying the value of an indexed parameter is illustrated inFig. 15 using the example of P0719. Follow the same procedureto alter other parameters using the operator panel.NOTE: In some cases when changing parameter values thedisplay on the operator panel displays P - - - - . This means thedrive is busy with tasks of higher priority.Changing Single Digits in Parameter Values — For changingthe parameters value rapidly, the single digits of the displaycan be changed by performing the following actions:Ensure the operator panel is in the parameter value changinglevel as described in the Changing Parameters with theOperator Panel section.1. PressFn(function button), which causes the farthestright digit to blink.2. Change the value of this digit by pressing or .3. Pressing Fn (function button) again to cause the nextdigit to blink.4. Perform steps 2 to 4 until the required value is displayed.5. Press P (parameter button) to exit the parameter valuechanging level.NOTE: The function button may also be used to acknowledgea fault condition.L3AOUT+ AOUT- P+ N-ONDIP SWITCH 2L2L1L3NL2D D+ -C CENABLEJUMPER12 13 14 15DIN1 DIN2 DIN3 24V+ 0V5 6 7 8 9RLB RLC10 11LL1UVW10V+ 0V AIN+ AIN-T1TO CONDENSERFAN MOTORT2T3Fig. 12 — Low Ambient Temperature ControlPower Wiring1 2 3 4+0-10 VDC FROM FAN BOARDNOTE: For 575-v units, jumper terminals are 5 and 9.–Fig. 13 — Low Ambient Temperature ControlSignal Wiring26
CHANGING P0004 — PARAMETER FILTER FUNCTIONSTEP1 Press to access parametersPRESULT ONDISPLAY2 Press until P0004 is displayedFig. 14 — Low Ambient Temperature ControllerQuick Commissioning (P0010=1) — It is important thatparameter P0010 is used for commissioning and P0003 is usedto select the number of parameters to be accessed. The P0010parameter allows a group of parameters to be selected that willenable quick commissioning. Parameters such as motor settingsand ramp settings are included. At the end of the quickcommissioning sequences, P3900 should be selected, which,when set to 1, will carry out the necessary motor calculationsand clear all other parameters (not included in P0010=1 to thedefault settings. This will only occur in Quick Commissioningmode. See Fig. 16.Reset to Factory Default — To reset all parameters to the factorydefault settings; the following parameters should be set asfollows:1. Set P0010=30.2. Set P0970 =1.NOTE: The reset process can take up to 3 minutes to complete.<strong>Troubleshooting</strong> with the Operating Panel — Warnings andfaults are displayed on the operating panel with Axxx andFxxx. The individual messages are shown in Table 21.If the motor fails to start, check the following:• Power is present on T1, T2 and T3.• Configuration jumpers are in place.• Control signal between 1 vdc and 10 vdc is present onterminals 3 and 4.• P0010 = 0.• P0700 = 2.Fault Messages (Tables 21 and 22) — In the event of a failure,the drive switches off and a fault code appears on thedisplay.NOTE: To reset the fault code, one of the following methodscan be used:1. Cycle the power to the drive.2. Press the Fn button on the operator panel.3 Press P to access the parametervalue level4 Press or to the requiredvalue5 Press P to confirm and store thevalue6 Only the command parameters arevisible to the user.CHANGING P0719 AN INDEXED PARAMETERSELECTION OF COMMAND/SETPOINT SOURCESTEP1 Press to access parametersP2 Press until P0719 is displayed3 Press P to access the parametervalue level4 Press to display current set valueP5 Press or to the requiredvalue6 Press P to confirm and store thevalue7 Press until r0000 is displayedRESULT ONDISPLAY8 Press P to return the display to thestandard drive display (as defined bythe customer)Fig. 15 — Changing Parameterswith the Operator Panel27
