Attention This product has been designed for Class A equipment. Use of the product in domestic environments may cause radio interference, in which case the installer may need to use additional mitigation methods.

  • Page 26: Wiring Considerations

    M2L 3000 Series VFD Wiring Considerations Wiring Practices When making power and control signal electrical connections, the following should be observed:  Never connect input AC power to the motor output terminals T1/U, T2/V, or T3/W.  Power wiring from the power source and to the motor must have the maximum possible physical separation- from all other wiring.

  • Page 30: Power Wiring

    M2L 3000 Series VFD Power Wiring Input Line Requirements The input line source needs to be an adequate source to start the motor, generally 2 times the rating of the motor FLA. (This may not apply in some cases such as being connected to a generator).

  • Page 31: Motor Lead Length

    The standard drive can operate a motor with a maximum of 600 feet of properly sized cable between the “T” leads of the drive and those of the motor. For wire runs greater than 600 feet contact Benshaw Inc. for application assis tance.

  • Page 33: Theory Of Operation

    The M2L 3000 product family is forced-air cooled, and spans a power range from 300 hp to 6,200 hp, operating at industry standard medium voltages up to 7200 VAC output. The drives can be used to control induction and wound field synchro- nous motors.

  • Page 34: Converter

    Figure 5: M2L 3000 Converter Typically, the primary voltage of the transformer is identical to the AC operating voltage of the motor; however, the M2L 3000 can accom- modate voltages that differ from the motor voltage. For example, a customer application may require that a 4160 VAC induction motor be operated from a 2300 VAC or 13.8k VAC source.
  • Page 35 4 – Theory of Operation Converter Details The standard transformer consists of a single 3-phase primary winding, with three 3- phase secondary windings that are phase displaced to produce an 18-pulse current waveform in the primary winding. The primary winding includes taps to adjust for slight variations in the incoming line voltage, to accommodate nominal, low, or high line con- ditions.

  • Page 36: Inverter

    IGBT Cell The standard building block in the M2L 3000 Converter is the “cell”. A variety of cell sizes are available, having different current ratings to configure drives at different power levels.
  • Page 37 4 – Theory of Operation A typical 4160VAC inverter contains eighteen (18) cells, arranged 6 cells per phase as shown in Figure 7. The cells are connected in series within each phase, and the phases are connected in parallel across the internal DC bus. DC voltage is divided evenly among the cells in each phase.
  • Page 38 M2L 3000 Series VFD WARNING: Do not remove the Cell or Input/Output Section covers to ac- cess the Inverter while the Inverter is energized. Potentially lethal levels of both AC and DC voltages will be exposed which may result in serious injury or death.

  • Page 42: Hmi Overview

    M2L 3000 Series VFD HMI Overview The HMI display can be divided into three primary areas: Selectable View Most of the HMI screen is dedicated to the active view, selectable at run time. The default view shows Speed Setpoint, Output Frequency, and general status indicators, intended to be visible at a distance.

  • Page 43: Status Indicators

    Start button will also turn green. Fault The M2L 3000 is designed to detect and report various fault conditions. When a fault occurs, the status indicator on the right and the Main button on the Navigation Menu will blink red. The name of the latched fault will appear across the top of the screen.
  • Page 44 M2L 3000 Series VFD Select Lockouts Warnings Limits from the navigation menu to view the specific lockout, warning, and limit conditions. For each status indicator on the Main view, multiple conditions could be present. NOTE: Lockout, Warning, and Limit conditions are not latched indefinitely, and can all be cleared without user interaction.

  • Page 46: Operating The Drive

    M2L 3000 Series VFD Operating the Drive With default parameter settings, the Drive can be fully operated from buttons on the HMI. If a plant PLC or some other control source is active, the Start and Stop buttons will not be available, and the speed setpoint will be shown as a meter.

  • Page 47: Selectable View Options

    5 - Operation Selectable View Options At any time, the navigation menu can be used to select different view options. Each view presents different information for monitoring the Drive meters or adjusting settings. Meter Values The Meter Values view displays real time feedback for the following values: DC Pole Voltage This value reflects voltage stored in the system capacitors.
  • Page 48 M2L 3000 Series VFD Meter Trending Real-time feedback is provided in the form of trending graphs. Two of five graphs can be displayed at any given time that reflect the following data: Current The three values on this graph reflect the actual three-phase current being applied to the motor.
  • Page 49 5 - Operation Parameter Settings System parameters can be viewed and adjusted from the HMI, to customize the behavior of the Drive. Parameter values are stored by the Drive, and retained when control power is lost. Refer to Section 5 - Parameter List for a listing of all user accessible parameters, and Section 6 - Parameter Descriptions for information regarding the usage of each parameter.
  • Page 50 M2L 3000 Series VFD Parameter sets can be used to quickly change multiple parameter values. This optional configuration allows the Drive to switch between different operation or load conditions without pausing to change numerous settings. Once parameter sets are configured, any changes made to specific parameter settings are only saved to the active parameter set, highlighted in blue.
  • Page 51 5 - Operation Inverter I/O This view shows the status of all inputs and outputs to the block of I/O located inside the Inverter cabinet. This information can be used to check control signals from the plant, and monitor any feedback. If the analog input and output values do not match those expected by the connected device, parameters for each I/O point can be adjusted.
  • Page 52 M2L 3000 Series VFD Cell Status This view displays meter values for each individual cell in the inverter. The top menu can be used to switch between phases (A, B, C). The cell numbers listed on the left of the screen correspond to the physical cell layout, and can be used as a reference when testing and replacing problematic cells.
  • Page 53 5 - Operation The system has the capability of displaying real-time feedback from an optional RTD (Resistance Temperature Detector) module. Up to 16 RTD channels can be monitored. The warning and trip level (in degrees Celsius) can be set individually for each RTD channel. Setting the trip level to zero for any channel indicates that no RTD is connected, and the value will not be displayed.
  • Page 54 Use the Newest button to return to the most recent events and re-enable this feature. NOTE: The HMI displays a selection of the most important events. Benshaw’s Event Viewer program for Windows can be used to load all events, and to more easily navigate to older events.
  • Page 55 5 - Operation Settings The HMI settings configure how the HMI displays information from the Drive. Unlike Parameter Settings, these have no effect on the operation of the Drive. Restore Trend Defaults This button reverts all trend displays to the factory default setting. Use this option to ensure full visibility on trended meters.
