CHAPTER 2
About the Drive
This chapter describes how to identify the drive using the model number matrix and shows the major drive components.
The LiquiFlo AC drive is a PWM (pulse-width-modulated) liquid-cooled drive that provides vector and general purpose regulation for a wide range of applications.
Using vector regulation, the drive can provide high dynamic response, maintain full rated motor torque to zero speed, and precisely control motor speed in both directions. The drive can provide this functionality either with encoder feedback (flux vector control or FVC) or without (sensorless vector control or SVC).
Using general purpose (volts/hertz or V/Hz) regulation, the drive is suited for a broad range of applications requiring adjustable speed control of motors.
2.1Identifying the Drive by Model Number
Each LiquiFlo AC drive can be identified by its model number. See figure 2.1. This number appears on the shipping label and on the drive’s nameplate. The drive’s model number includes the Power Module and the regulator version. Drive power ratings are provided in table 2.1.

2.6Regulator Board Description
LiquiFlo drive regulation is performed by a microprocessor on the Regulator board. See figure 2.5. Drive operation is adjusted by the parameters entered through the keypad. The Regulator board accepts power circuit feedback signals and an external speed reference signal, as well as data from an encoder that is attached to the motor when set up for FVC regulation. The Regulator board provides:
•PWM gating signals to the IGBT power devices
Based on the output of the control loop, the regulator sends PWM gating signals to isolated drivers on the Gate Driver board. These drivers switch the Insulated Gate Bi-polar Transistors (IGBTs), producing a waveform that corresponds to the voltage and frequency outputs of the inner V/Hz, FVC, or SVC regulators. The IGBTs can be switched at either a 2, 4, or 8 kHz carrier frequency.
•Form A and B contacts for drive status indicators
The Form A and B contacts are under control of the user via programmable parameters. A Form A or B transition can indicate drive status. The contacts are rated for 5 amps resistive load at 250 VAC/30 VDC and are made available through the terminal strip.
•Display data for a four-character display and fourteen indicator LEDs
For a description of the keypad/display refer to section 2.6.6. For operational instructions, see the LiquiFlo Software Reference manual (D2-3410).
•An analog output
The analog output is a scaled voltage (0-10 VDC) or current (4-20 mA) signal proportional to either motor speed (RPM), motor torque, or current (%TORQUE). The current signal selection (via jumper J17) requires a power supply for operation. The power can be sourced from the encoder terminals (4 and 9) or from an external 15 V power supply. See table 7.1, terminals 10 and 11, for more information. The analog output signal is available through the terminal strip.

2.6.1 Jumper Locations and Settings
Jumpers J4 and J17 on the Regulator board are factory-set for voltage in and voltage out signals. Refer to figure 2.5 for their locations on the Regulator board. If you need to change the jumpers’ settings, use the following procedures.
ATTENTION: Do not alter the setting of any jumper not described in this instruction manual. Failure to observe this precaution could result in
!damage to, or destruction of, the equipment.
2.6.1.1Setting the Analog Input Speed Reference Jumper (J4)
Jumper J4 is the analog speed/torque (U.000) reference jumper. This jumper selects either +/- 10 VDC or 0-20 mA input. Parameters P.009, P.010, and P.011 are used in conjunction with the jumper.
Note that if the position of jumper J4 is changed after the parameters are programmed, the software will not recognize that the input reference or polarity has been changed. Be sure to verify that parameters P.009, P.010, and P.011 are correct before starting the drive. Refer to the LiquiFlo Software Start-Up and Reference manual for more information.
Use the following procedure to set jumper J4:
ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait five
!(5) 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.
Step 1. Turn off input power to the drive and wait five minutes.
Step 2. Open the door of the enclosure.
Step 3. Verify that the DC bus voltage is zero by following the procedure in section 9.3.
Step 4. Locate jumper J4 on the Regulator board. Refer to figure 2.5.
Step 5. Locate pin 1 on jumper J4. Move the jumper to the desired setting as shown in figure 2.6.
Step 6. Close the door of the enclosure.
Step 7. Reapply input power.

Step 8. Verify that Terminal Strip Analog Input Offset (P.009), Terminal Strip Analog Input Gain (P.010), and Terminal Strip Analog Input Configure (P.011) are correctly set. Note that the jumper settings must match the software settings; otherwise, the reference value may differ from what is expected. Refer to the LiquiFlo Software Start-Up and Reference manual for more information.

2.6.1.2Setting the Analog Output Jumper (J17)
Jumper J17 is the analog output jumper. This jumper selects either a 0-10 VDC or 4-20 mA scaled signal output that is programmable to be proportional to either speed or torque using parameter P.012. Refer to the LiquiFlo Software Reference manual for more information about this parameter.
The jumper only selects a 0-10 VDC source voltage or 4-20 mA sink current to represent speed or torque. Note that the 4-20 mA current selection requires a power supply for operation as shown in table 7.8, terminals 10 and 11.
Use the following procedure to set jumper J17:
ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait five
!(5) 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.
Step 1. Turn off input power to the drive and wait five minutes.
Step 2. Open the door of the enclosure.
Step 3. Verify that the DC bus voltage is zero by following the procedure in section 9.3.

Figure 2.8 – Typical Regulator Board Terminal Strip Connections
2.6.3 RS-232 Communication Port
The Regulator board contains a 9-pin D-shell RS-232 communication port (J8). This port provides RS-232 communication between the LiquiFlo drive and a personal computer running the Control and Configuration (CS3000) software. See figure 2.5. Refer to instruction manual D2-3348 for more information about the CS3000 software.
2.6.4 RMI Board Connector
The flat-ribbon cable connector (J3) on the left side of the Regulator board is a parallel bus connection port that is used on LiquiFlo drives for the Remote Meter Interface (RMI) board.
The RMI board provides an extended set of terminal strip inputs and outputs for the LiquiFlo drive. When the drive control source is the terminal strip (P.000 = rE), the RMI board can be used to provide additional speed reference selections. The RMI board also provides an outer PI regulator that is used to adjust trim. An optional adjustable torque (vector) or current (V/Hz) limit is available using the RMI board's analog or frequency input. See section 2.7 for a more detailed description of the RMI board. Refer to section 7.4 for a detailed description of the RMI terminal strip signals, and how to wire the RMI board.
The J3 connector can also be used to provide a means of attaching optional boards such as the DeviceNet™ Option board, the AutoMax™ Network Option board, or similar boards to the LiquiFlo drive. Note that you must first remove the RMI board before a communication board can be added to the LiquiFlo drive.
