PREFACE This manual is a start-up and programming reference guide for the version 6.4 LiquiFlo™ drive. The drive can be set up for either volts per hertz (V/Hz) or vector regulation. This manual provides a start-up procedure for both. The start-up procedures are followed by reference information. This information includes a complete list of all parameters and a description of the keypad/display. • You will need to know how to use the keypad to perform the start-up procedures described in chapters 1 and 2.

CHAPTER 1 Starting Up the Drive for Volts/Hertz Regulation This chapter describes the basic start-up procedure for drives which utilize open-loop V/Hz regulation. V/Hz regulation is the default method of regulation. You do not need to select it. If you are starting up a drive which will perform vector regulation, refer to the vector start-up procedure in chapter 2.0 instead. Do not perform the start-up procedure in this chapter.
PAGE 12
1.1 Preparing for Start Up (Volts/Hertz) Read through the following sections to prepare for the start-up procedure. What You Need to Know: • You must be qualified to perform the procedure and be familiar with V/Hz regulation. • You should be familiar with the keypad/display. If you are not familiar with the keypad/display, refer to chapter 3, which describes it. What You Need to Do: • Complete all hardware installation as described in the hardware reference manual.

To Restore All the Default Values to General (P) Parameters: If you need to restore all the default values for General (P) parameters after programming them, you can do so using the Restore Defaults parameter (P.050). 1.2 Start-Up Procedure (Volts/Hertz) This section describes the start-up procedure for drives set up for V/Hz regulation. Before using this procedure, you should have read section 1.1 for information you need to know before working with the drive. Step 1.

CHAPTER 3 Using the Keypad/Display to Program, Monitor, and Control the Drive The front-panel keypad/display is used to program, monitor, and control the drive. It operates in two modes, monitor mode and program mode. The functions available at the keypad depend on what mode the keypad/display is in and what is selected as the drive control source. In monitor mode (the default mode), you can monitor specific drive outputs as well as enter the speed or frequency reference for the drive.
PAGE 74
3.1 Monitor Mode Monitor mode is the keypad/display’s default mode during drive operation or it is entered by pressing the PROGRAM key until the PROGRAM LED turns off. The following output data can be displayed in monitor mode: • Speed • Volts • Amps • Hz • Kw • Torque (vector regulation only) • Selected reference (speed or torque) To select a value to monitor, press the ENTER key until the LED turns on next to the desired display item. Pressing the ENTER key advances you through each of the displays.
PAGE 75
Step 2. Press the ENTER key repeatedly to advance through each of the monitor mode LEDs. All of the monitor mode LEDs will then turn on at once and the reference will be displayed. Note that the displayed speed reference value is scaled based on P.028. The torque reference value is displayed in percent.

CHAPTER 5 Troubleshooting the Drive Using Error Codes The drive can display two kinds of error codes, called alarm and fault codes, to signal a problem detected during self tuning or drive operation. Fault and alarm codes are shown in tables 5.1 and 5.2. A special type of fault code, which occurs rarely, is the fatal fault code. If the code you see is not in tables 5.1 or 5.2, refer to section 5.4. Alarm Codes An alarm condition is signified by a two- or three-letter code flashing on the display.
PAGE 174
5.1 Identifying Alarm Codes and Recovering LiquiFlo drive alarm codes are shown in table 5.1. Note that the alarm code will only be displayed for as long as the problem exists. Once the problem has been corrected, the alarm code will disappear from the display. Table 5.1 – List of Alarm Codes Code HIdc Alarm Description High DC bus voltage Alarm Cause The DC bus is charged above the trip threshold. (If U.018 > 415, DC bus is above 741 VDC. If U.018 ≤ 415, DC bus is above 669 VDC.
PAGE 175
5.2 Identifying Fault Codes and Recovering ! ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait five minutes for the DC bus capacitors to discharge and then check the voltage with a voltmeter to ensure the DC bus capacitors are discharged before touching any internal components. Failure to observe this precaution could result in severe bodily injury or loss of life. LiquiFlo drive fault codes are shown in table 5.2.

5.4 Identifying Fatal Fault Codes and Recovering Fatal fault codes are distinguished by the letter F preceding the code. They normally indicate a malfunction of the microprocessor on the Regulator board. In some cases, fatal fault codes can be reset and the drive can be re-started. Table 5.3 lists the fatal fault codes which can be reset. If any other fault code appears on the display, you will need to replace the Regulator board.

APPENDIX F Using the Terminal Strip Analog Input An analog reference input is provided at terminals 12 through 15 on the drive’s Regulator board. This input accepts either a +/-10 VDC or 0 to 20 mA signal. The analog-to-digital conversion provides 10-bit plus sign resolution and a digital range of +/-1023. The analog input can be used as a reference for: • Speed reference (P.000, P.007/P.008) • Trim reference (P.014) • Torque reference (vector control only) (U.000) • Outer control loop feedback (U.

F.1 Configuring the Analog Input Parameter P.011 is used to specify the type of input and whether it is to be inverted after it is converted by the drive. The parameter setting should coincide with the position of jumper J4 on the Regulator board. For example, if a voltage input is applied, J4 should be set to +/- 10 VDC and P.011 should be between 0 and 3. If a current input is applied, J4 should be set to 0 to 20 mA and P.011 should be between 4 and 7. If P.

Figure F.2 illustrates how the analog signal is scaled internally by the drive when it is used as the speed or trim reference. The solid line indicates the conversion when the non-inverted state is selected (P.011 is even). The dashed line indicates the conversion when the inverted state is selected (P.011 is odd). +Max Spd (P.004) +Min Spd (P.003) -10 vdc -Min Spd (P.003) +10 vdc +20 ma -Max Spd (P.004) Terminal Strip Analog Input P.011 is even = non-inverted P.011 is odd = inverted Figure F.

To adjust the offset (P.009): Step 1. Verify that the analog input is configured as the speed reference control source (P.000 = rE or LOCL and AUTO is selected), P.008 = 0, and U.000 = 0). Step 2. Display the converted value of the analog input using the selected speed reference display mode. (Refer to chapter 3 for the procedure for displaying the selected speed reference.) Step 3. Adjust P.

• The maximum negative analog input value (-10VDC) corresponds to the negative torque limit of the drive (-150% of the rated motor torque). • The minimum analog input value (0 VDC or 0 mA) corresponds to zero torque reference. Refer to the LiquiFlo drive hardware reference manual for terminal location, wiring guidelines, and jumper settings. F.

The control source must be the terminal strip (P.

F.4.1.2 Start Threshold Range The default value of the start threshold is 33 A/D counts, which corresponds to 0.33 VDC (nominal). The start threshold minimum value is 0 counts. The start threshold maximum value is 2000 counts. F.4.2 Using the Level Sense Start Enable Feature and the Analog Input Start/Stop Feature The level sense start enable feature, configured with parameter P.054 (Level Sense Start Enable), can be used with the analog input start/stop feature.

APPENDIX G Drive Regulation Overview The LiquiFlo digital drive provides vector or volts/hertz regulation of AC motors. Parameter P.048 (Volts/Hertz or Vector Regulation) is used to select the type of regulation for the application. Volts/Hertz Regulation (P.048 = U-H) Volts/hertz regulation provides general-purpose open-loop AC drive control. It does not use an encoder feedback device.

If a Remote Meter Interface (RMI) board is installed, P.064 is used to select the OCL reference as follows for FVC/SVC applications only: • 0 = RMI analog input • 1 to 8 = Preset speed 1 to 8 (P.031 to P.038), respectively If no option board is installed, P.064 is used to select the OCL reference for FVC/SVC applications only: • 0 = Preset speed 8 (P.038) • 1 to 8 = Preset speed 1 to 8 (P.031 to P.
