  • Page 2 Danfoss FC Drive LCP Display Layout Danfoss FC drives have a total of 5 possible variables that can be set up and displayed to the user. There is also a 3 word status line at the bottom of the display. The status line tells you what the drive is doing, or being commanded to do.
  • Page 3 These variables can be viewed temporarily using the given “Data Readout” parameters, or set up on the display permanently in the “Operation / Display” (0-20) menu group 177R0521-VLT_Aqua_Drive_Training_Handout_BODY.indd 2 4/29/15 2:47 PM...

  • Page 4: Status Messages

    Status Messages As stated previously, the bottom line tells you the current status of the drive. The first (left) word will appear as either “Hand”, “Off” or “Auto”. This indicates what type of control the drive is set for. Hand means the drive is started locally by the LCP “Hand On”...

  • Page 5: Operation Status

    Below are a list of the actual status words (far right on display) and what they mean Operation Status AC Brake AC-Brake was selected in par. 2-10 Brake Function. The motor is slowed down via the active down ramp and feeds the FC with generative energy. The AC Brake over-magnetizes the motor to achieve a controlled end of the active ramp.
  • Page 6 Bus Jog 2 PROFIDrive profile was selected in par. 8-10 Control Word Profile. Via serial communication the Jog 2 function is activated. The Motor is running with par. 8-91 Bus Jog 2 Speed. Catch up The output frequency is corrected by the value set in par. 3-12 Catch up/slow Down Value. 1.

  • Page 7: Freeze Output

    DC Voltage U0 In par. 1-01 Motor Control Principle U/f and in par. 1-80 Function at Stop DC-Voltage U0 is selected. A Stop command (e.g. Stop (inverse)) is activated. The Voltage selected according to the par. 1-55 U/f Characteristic - U [0] (U/f-Characteristic – U[V]) is applied to the Motor. Feedback high In par.
  • Page 8 Kinetic back-up In par. 14-10 Mains Failure a function was set as Kinetic back-up. The Mains Voltage is below the value set in par. 14-11 Mains Voltage at Mains Fault. The FC is running the motor momentarily with kinetic energy from the inertia of the load. Motor check (FC 100/200 only) In par.

  • Page 14 Danfoss FC Series VFD Reference Handling There are some distinct differences in the handling and setup of reference signals in the FC series drives when compared to legacy products. This tutorial will explain how to interpret the reference parameters and achieve the desired results.
  • Page 15 Now you need to define where your references will come from. This is done in the 3-1 parameter group. Parameters 3-10, 3-15, 3-16 & 3-17 are all parameters will that allow you set up your reference sources. If you want to use multiple reference points, then you must define them here. Most applications will only use one reference terminal rather than multiples.

  • Page 17 VLT Aqua Drive Lab # 1 Introduction In this lab you will set up a VLT Aqua drive to operate in “Hand Mode”. This is the simplest form of operation and consists of using the drives LCP to operate the drive manually.

  • Page 18: Mechanical Setup

    Mechanical Setup Plug in the demo drives power cord into a 120 volt outlet Connect the motor to the drive. Drive terminals 96, 97 & 98 are used for the motor connections. Also connect the motor ground wire to the drive chassis. Place a jumper wire between control card terminals 12 &...

  • Page 19: Verifying Operation

    There are 12 parameters in the quick menu. You can use the up and down arrow keys to scroll through the following parameters. Using the motor nameplate data, enter parameters 1-20 through 1-25 in ascending order. Set the remaining quick menu parameters to the values shown in the list.
  • Page 20 (Open Loop Speed Control) Introduction In this lab you will set up a VLT AQUA drive to simulate a wastewater pumping application. The drive will be set up in an open loop configuration. In an “open loop” configuration the reference signal fed into the drive is directly proportional to the speed it will run at. The drive will receive the control signals by means of a SCADA system.
  • Page 21 Identify the drives power connections and control card terminals Program the necessary drive parameters for basic open loop control Learn to identify and wire the electrical & I/O connections to the VLT Aqua Drive Use the drives data readouts to verify that the hardware is working correctly...
  • Page 22 Which 3 terminals are used for power supply common, or 0 volts? _________ How many digital inputs are available? _________ How many analog inputs are available? _________ Which terminal is used for the analog output? _________ For this lab, the switch box pictured below will simulate the SCADA signals. You will use switches S1 - S6 to apply +24 VDC to the drives digital inputs for activation.
  • Page 23 Software Setup You will want to start programming the drive from scratch. Performing an “initialization” will reset all parameters back to the factory default. With power off, simultaneously hold down the “status, main menu & OK” keys. Apply power and continue to hold the buttons for at least 5 seconds after you apply power to the drive.

  • Page 25 Now you need to program and wire your start command. Go to parameter 5-10. This parameter defines the function of digital input 18. Notice that the default setting is programmed to “start”, so no programming change is necessary. Switch S1 from your control box should be connected to DI 18 on the drive. This switch will act as the start command.
  • Page 26 Parameter 16-62 can be used to display the analogue voltage signal on AI 53. Turn “POT #1” (AI53) from left to right and verify that the voltage on the terminal varies from 0 to 10 volts. The final step is to program a relay for alarm indication. Go to parameter 5-40 and change relay # 1 to the function “Running/No Warning”.
  • Page 27 (Process Closed Loop Operation) Introduction In this lab you will set up a VLT Aqua drive to simulate a closed loop pumping application. When a VFD is set up for “closed loop operation”, it requires a set-point and some sort of feedback from the system.
  • Page 28 S1 - S6 to apply +24 VDC to the drives digital inputs for activation. In order for the VLT AQUA drive to run in a closed loop configuration, it must have a pressure transducer wired directly to it. This lab is only a simulation of a pumping application, so there will be no actual pressure.
  • Page 29 Software Setup You will want to start programming the drive from scratch. Performing an “initialization” will reset all parameters back to the factory default. With power off, simultaneously hold down the “status, main menu & OK” keys. Apply power and continue to hold the buttons for about 5 seconds after you apply power to the drive.
  • Page 30 The “Quick Menu” on the VLT AQUA drive can be used to set up a closed loop program. Press the “Quick Menus” key and enter “Q3 Function Setups”. Next go to “Q3-3 Closed Loop Settings”. Both Q3-30 & Q3-31 will need to be gone through to complete the setup. Start by scrolling through the parameters in “Q3-30”...
  • Page 31 Those parameters are used to set up a function called “Live Zero”. Parameter 6-00 is the “Live Zero” timeout time, and 6-01 is the “Live Zero” function. How it works is as follows; if the analog signal on AI 53 or 54 falls below 50% of the minimum scaling of that input (P6-10 or P6-20), the drive will start to count down from the time set in P6-00.
  • Page 32 Verifying Operation Press the “Auto On” button at the bottom of the keypad. Close the switch wired to DI 27 and reset the alarm if necessary With the remaining switches off, the display status word reads “auto remote standby” Start the drive with S1 (DI18) and modulate the feedback above and below the set- point.
  • Page 33 (Pump Application Ramp Profiles) Introduction In this lab you will set up a VLT Aqua drive to provide a customized ramp profile for submersible pump applications. The pump needs to get to minimum speed in order to begin lubricating the bearings and moving water. From the initial speed until the “PID Start Speed”...

  • Page 37 Software Setup If you have completed lab #3, you will only need to program the RTC settings shown below. If you are starting from scratch, set the drive up for closed loop constant pressure (lab # 3) before you move forward from this point. Connect your demo drive to your laptop via the USB port.
  • Page 38 Now that the clock is set, we will display the time on our LCP. Go to parameter 024 and change it to the value “Date and Time Readout”. Verify that the time is now displayed correctly. The last step is to set up your time based actions. The golf course owner wants to water one hole at a time for one hour each.
