WARNINGS HAZARDS OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH.
Failure to follow the instructions below may result in serious injury or death.
DANGER. This equipment does not provide isolation. Separate isolating
means required. Isolation devices can take several forms with the most
simple being an appropriately sized disconnect switch and contactor pair
utilizing the Inverter ‘Shunt Trip’ controls, or an appropriately sized and
protected vacuum circuit breaker also capable of remote operation from
the inverter ‘Shunt Trip’ controls. See page 32 for more information.
WARNING: At any time the system is energized with Medium Voltage
power, apply appropriate personal protective equipment (PPE) and follow
safe electrical work practices when operating or working near the system.
See NFPA 70E.
Cabinet Fault Limit: <10kA @ 10 Cycles
Min Arc Boundary: 40 Inches
Recommended Min. PPE: #1 at > 40 inches
WARNING: Branch circuit protection is required for the equipment. See
page 32 for more information.
WARNING: Only qualified personnel familiar with the use and hazards of
medium voltage equipment are to perform work described in this set of
instructions.
WARNING: Before performing visual inspections, tests, or maintenance
on the equipment, disconnect all sources of electric power. Assume that
circuits are live until completely de-energized, tested, and tagged.
Pay particular attention to the design of the power system. Consider all
sources of power, including the possibility of backfeeding.
Use a properly rated voltage sensing device to confirm that the power is
fully removed.
WARNING: Always perform applicable lock-out/tag-out procedures (either general or site-specific) before performing any maintenance or troubleshooting on the system.
WARNING: To avoid potentially lethal levels of both AC and DC voltages,
do not remove the cover to access the MV Input/Output section of the Inverter while the Inverter is energized.
WARNING: Equipment may be supplied from multiple power sources.
Refer to drawings for more information.

wire
CAUTIONS
WARNING: Potentially hazardous voltages will remain in the cells until
the capacitors are able to de-energize. Wait at least 30 minutes after
main power is removed for the stored voltages to dissipate if removing
the Inverter Cell or Input/Output section covers. Do not rely solely on the
voltage values displayed on the HMI Meter Values screen to determine if
it is safe to remove the covers on the Inverter Cell and Input/Output sections.
WARNING: The Control section contains 240V control power when active. The Control section does not contain medium voltage levels supplied from the mains, and can be carefully accessed by qualified personnel while medium voltage from the AC mains is applied to the system.
WARNING: Replace all devices, doors, and covers before applying
power to this equipment.
WARNING: Do not attempt to lift and position either the Converter or Inverter with a crane without the proper equipment or experience performing this type of operation. Benshaw can arrange the services of professional firms who routinely rig and lift heavy equipment.
CAUTION: Special care must be taken with covers that have a ground
attached to the inside that ties them to ground potential. It is important that the connection integrity of this wire be maintained to avoid
compromising the immunity of the Inverter to Electromagnetic Interference (EMI) and safety.
CAUTION: Always be aware of electrostatic discharge (ESD) when working near or touching components inside the drive. Handling of components sensitive to ESD should be done by qualified personnel only, familiar with ESD mitigation techniques.
CAUTION: Parameter settings and adjustments should be performed by
those familiar with VFD and motor operation characteristics. It is not recommended for users unfamiliar with these concepts.

Energy Efficiency
Energy Savings
Unique modular inverter design has improved efficiency over Cascaded H-
Bridge and Neutral Point Clamped (NPC) inverter designs.
Uses the latest in efficient IGBT designs for minimum losses and maximum
performance.
Inverter efficiency >99% over a wide speed range and wide load range
Modular inverter design allowing the input converter to operate more effi-
ciently than other inverter designs reducing losses
No efficiency reducing output transformers or output filters are required
Input power supply power factor of ≥0.95 minimizes losses in the power sup-
ply and input wiring
Shaft power of motor driven equipment (fans, pumps, blower) is proportional
to the cube of the rotational speed
By design, VFDs improve efficiency at low speeds
Considerable energy savings can be achieved by outfitting motors with VFDs,
as the speed can be adjusted to match the required load

EMC Installation Guidelines
General
In order to help our customers comply with European electromagnetic compatibility standards, Benshaw
Inc. has developed the following guidelines.
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.
Enclosure
Install the product in a grounded metal enclosure.
Grounding
Connect a grounding conductor to the screw or terminal provided as standard on each controller. Refer to lay
out/power wiring schematic for grounding provision location.
Wiring
Refer to Wiring Practices on page 26.

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. Do not run control wiring or signal wiring in the same conduit; this separation reduces
the possibility of coupling electrical noise between circuits. Minimum spacing between metallic conduits containing different wire groups should be three inches (8cm).
Minimum spacing between different wiring groups in the same wire tray should be six inches (15 cm)
Wire runs outside an enclosure should be run in metallic conduit or have shielding/armor with equivalent atten-
uation.
Whenever power and control or signal wiring cross, it should be at a 90 degree angle.
Different wire groups should be run in separate conduits.
NOTE: Local electrical codes must be adhered to for all wiring practices.
Considerations for Control and Power Wiring
Control wiring refers to wires connected to control terminal strips that normally carry 24V to 115V. AC Power wiring
refers to wires connected to the line and load terminals that normally carries 4160VAC. Power wiring for cabinet
fans carries 240VAC. DC Power wiring refers to wires connected to terminals that normally carry 6400VDC. Select
power wiring as follows:
Use only UL or CSA recognized wire.
Grounding must be in accordance with NEC, CEC, or local codes. If multiple Drives are installed, then each
Drive must be individually connected to ground. Take care not to form a ground loop. The grounds should be
connected in a STAR configuration.
Considerations for Signal Wiring
Signal wiring refers to the wires connected to control terminal strips that are low voltage signals, below 15V.
Shielded wire is recommended to prevent electrical noise interference from causing improper operation or nui-
sance tripping.
Signal wire rating should carry as high of a voltage rating as possible, normally at least 300V.
It is important to keep the routing of signal wiring as far away from control and power wiring as possible.
Meggering a Motor
If the motor needs to be meggered, remove the motor leads from the Drive before conducting the test. Failure to
comply may damage the IGBTs and WILL damage the control circuitry, which WILL NOT be replaced under warranty.
High Pot (High Potential) Testing
If the Drive needs to be high pot tested, perform a DC high pot test. The maximum high pot voltage must not exceed 8520VDC. Failure to comply WILL damage the control circuitry, which WILL NOT be replaced under warranty.
Note: For Inverter High Pot Test, both control cables connected to the sides of the Pre-Charge Board need to
be temporarily disconnected.

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).
Recommended Wire Gauges
The wire gauge selection is based on the FLA of the motor. Refer to NEC table 310, 60 or CEC Part 1, Table 2 or
local code requirements for selecting the correct wire sizing. Ensure appropriate wire derating for temperature is
applied. In some areas local codes may take precedence over the NEC or CEC. Refer to your local requirements.
Power Wire Connections
Attach the motor cables:
• Use the T1, T2 and T3 terminals. Use lugs/crimps or terminals (lugs and crimps are to be provided by the
customer).
Attach the power source cables:
• Use the L1, L2 and L3 terminals. Use lugs/crimps or terminals (lugs and crimps are to be provided by the
customer).

The Benshaw M2L 3000 family of medium voltage variable frequency motor drives features a unique power circuit, and a
state-of-the-art control platform, to provide the utmost in performance and application flexibility.
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 synchronous motors.
This section provides an overview of the drive architecture, along with descriptions of major system components.
M2L 3000 Overview
The M2L 3000 variable frequency drive consists of two major system elements, shown in Figure 4; A Converter (Input
Power Stage) and an Inverter (Output Power Stage). The purpose of the Converter is to convert incoming voltage from the
AC mains into DC. The DC is passed to the Inverter using standard high-voltage shielded cable, where it is converted into
variable voltage, variable frequency 3-phase AC, then applied to the motor.

Most modern MV VFDs employ dual energy conversions (i.e. AC-to-DC and AC-to-DC), but are constrained to have these
constituent elements located in close physical proximity to each other, to avoid electrical complications that would compromise the operation of the drive, and adversely affect reliability. The M2L 3000 is not constrained in this manner. The Inverter
can be located adjacent to, or remotely from, the Converter without causing any adverse affects on the operation of the
drive. This feature imparts great application flexibility to users who may have space constraints, or choose to locate the heat
producing Converter away from environmentally conditioned equipment rooms or spaces.
33
M2L 3000 Series VFD
Converter
The Converter, or Input Stage, consists of a medium voltage transformer and full-bridge rectifiers that convert the incoming AC mains
voltage to a fixed source of DC. Individual 3-phase bridge rectifiers
are connected in series, as shown in Figure 5, to produce the required DC voltage for the inverter.
The Converter does not contain any capacitors for energy storage.
Energy storage in the drive is distributed among identical power
modules in the drive’s Inverter. The distributed capacitive energy
storage greatly reduces arc flash potential and substantially improves reliability.
The transformer is a standard rectifier grade transformer consisting
of a single 3-phase primary winding, with three (3) secondary windings, appropriately phase shifted to yield an 18-pulse current waveform in the primary for low harmonic distortion. The total harmonic
distortion (THD) of the primary current is typically ~2.3% for a 1000
hp, 4160 VAC drive operating at full power, which easily complies
with IEEE 519 distortion requirements.
Typically, the primary voltage of the transformer is identical to the AC
operating voltage of the motor; however, the M2L 3000 can accommodate 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. In this case, the
primary winding would be specified to be 2300 VAC or 13.8 kVAC.
The secondary winding voltages have been selected to generate the
DC voltage needed to synthesize AC waveforms for 4160 VAC at its
output terminals.
Two typical size Converter enclosures (small and large frame) are
shown in Figure 6, with all electrical components contained within the
enclosures. The enclosure design allows for top or bottom entry of all
cable connections between the AC mains and the Inverter.
The Converter is forced-air cooled. Cooling air is drawn through filters on the front of the enclosure by multiple blowers mounted on the
top. The Converter is designed to function with “N-1 Redundancy”
(for example only 2 of 3, or 4 of 5 blowers operating), providing redundant protection and high operating availability. Filter elements are
provided in series on the front of the enclosure, to block the ingress
of dirt and dust particulates. The filter assembly mounts over a protective screen, welded to the enclosure, that prevents inadvertent
contact with the resident high voltages when the filter media is removed for cleaning or replacement.
The enclosure also contains internal baffles that route air flow
through critical areas of the transformer, and across the rectifier assemblies. Thermal sensors are located in the input air stream to the
blowers, to detect over temperature conditions. The standard Converter enclosure is rated for NEMA 1 applications. Enclosures with
other environmental ratings are available.

Converter Details
The standard transformer consists of a single 3-phase primary winding, with three 3phase 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 conditions. Variations of ±5% can be accommodated by jumpering the incoming AC cables
to the to +5% tap for high line conditions and the -5% tap for low line conditions.
Three secondary windings are physically shifted on the transformer core to yield voltages that are phase displaced by ±20 electrical degrees with respect to the primary
winding. Figure 4 shows the schematic diagram of a typical transformer.
Each secondary winding is connected to a dedicated 6-pulse, full-wave bridge rectifier
that converts AC to DC, as shown schematically in Figure 7.
The DC terminals of all three (3) rectifier bridges are connected in series, such that the
appropriate output voltage is generated at the output of the VFD.

Inverter
The role of the Inverter is to convert DC voltage produced by the Converter to variable voltage, variable frequency AC, to be
applied to the motor terminals. The Inverter utilizes a topology known as Modular Multi-Level Converter (M2LC), which offers
many benefits.
M2LC topology allows the Converter to be located remotely from the Inverter, for the ultimate in application flexibility. The
Inverter is a modular design enabling rapid drive repair by simple removal and replacement of a faulty module or “cell”. Replacing a cell can be done in a matter of minutes, minimizing downtime and process interruption.
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.
A cell consists of Insulated Gate Bipolar Transistors (IGBTs), capacitors, associated
control, communication and gating circuitry, heatsinks, and sensors; all housed in a
metal enclosure. A depiction of the cell is shown below in Figure 9.
Figure 9: IGBT Cell
Each cell contains IGBT switching devices and film capacitors. These film capacitors
offer significant improvements over conventional electrolytic capacitor technologies.
This technology is more stable, and safer, than conventional capacitors that can explode from the buildup of high pressures within the capacitor if a failure should occur.
Embedded cell circuitry provides intelligence for control and communication. Communication with the central control system of the drive occurs over optical fiber, using an
Ethernet protocol that greatly improves speed and noise immunity. Each cell is designed to sense voltage and current, eliminating the need to place external voltage and
current sensors on the motor leads.
The elimination of external sensors removes single points of failure, improving drive reliability.

AC Outputs
Inverter Packaging
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.
The cells in each phase work together to create the AC output waveform. Pulse width
modulation (PWM) control is used to convert DC voltage into a low distortion AC waveform, which is applied to the motor terminals labeled A, B and C in Figure 10. Each output phase provides an equivalent waveform for optimal harmonic characteristics. As
such, output filters are not required. Additionally, the Inverter has been designed to
work with standard, non-inverter grade motors commonly found in use today.

The front view of a typical small frame 1500 hp Inverter is shown below in Figure 11.
Other specialized configurations of the Inverter can be utilized for higher horsepower
and/or voltage applications. The typical enclosure is partitioned into 3 sections: Cell, Input/Output and Control. The enclosure contains internal structural members that provide strength, rigidity and voltage isolation, with bolt-on metal covers for each section
attached to the structural members.

WARNING: Do not remove the Cell or Input/Output Section covers to access 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.
WARNING: Potentially hazardous voltages will remain in the cells until
the internal capacitors are able to de-energize. Wait at least 30 minutes
after main power is removed for the stored voltages to dissipate if removing the Inverter Cell or Input/Output section covers. Do not rely solely on
the voltage values displayed on the HMI to determine if it is safe to remove the covers on the Inverter Cell and Input/Output sections.
WARNING: The Control section contains 240V control power when active. The Control section does not contain medium voltage levels supplied from the mains, and can be carefully accessed by qualified personnel while medium voltage from the AC mains is applied to the system.
CAUTION: Special care must be taken with the cover over the Control
section and all access panels. A ground wire is attached to the inside of
that cover that ties it to ground potential. It is important that the connection integrity of this wire be maintained to avoid compromising the immunity of the Inverter to Electromagnetic Interference (EMI.).

Figure 12: Typical 1500 hp Inverter – Front View with Covers Removed
Figure 12 represents a typical small frame, 1500 hp, 18 Cell Inverter with the front covers removed. IGBT cells can be seen as 3 vertical columns in the right side of the enclosure. The leftmost vertical column, located closest to the center of the enclosure, is
Phase A followed by Phases B and C. The AC midpoint of each phase is located behind
the grey panels covering the AC terminals and inductive filters.
Internal cabling routes the AC outputs from the phases to the Input/Output section of the
Inverter, in the area located in the lower left of the enclosure. Also shown in this section
are components associated with the pre-charge function and current loop power for the
IGBT cells.
The Input/Output section of the enclosure is the area where power connections are
made to the Inverter. AC output cables from the motor are attached to landing pads on
the right side of the Input/Output section, while high voltage cables that interconnect the
Converter and Inverter are attached to landing pads on the left side. The enclosure allows for top or bottom entry of both AC and DC cables.
The Inverter is forced-air cooled. Air is drawn through filters on the front of the enclosure
by blowers mounted on the top. The Inverter is designed to function with only 3 of the 4
blowers operating at any given time, providing redundancy and high operating availability. Two filter elements are provided in series on the front of the enclosure to block the
ingress of dirt and dust particles. The filter assembly mounts over a protective screen,
ages when the filter media is removed for cleaning or replacement.
The compartmental nature of the Inverter’s internal design provides baffling to route air
flow through critical areas of the enclosure. The standard Inverter enclosure is rated for
NEMA 1 applications.
For testing and checkout purposes, the Inverter is designed with a power supply system
that enables control power to be applied without medium voltage main power being applied.

5 - Operation
This section provides basic operation instructions for the M2L 3000 HMI (Human-Machine Interface) controller.
WARNING: Only qualified personnel familiar with the use and hazards of
medium voltage equipment are to perform work described in this set of
instructions.
Introduction The HMI is an interactive controller and display which provides the ability to both monitor and
control operation of the drive.
Custom parameters are accessible to modify the characteristics of drive performance. Refer to
Section 5 - Parameter List, for the complete list of user accessible parameters in tabular format,
and to Section 6 - Parameter Descriptions, for explanations of how each parameter is used. Initial
setup of basic parameters may be required for your site application, and should be configured
during drive commissioning. Many parameters can also be adjusted while the drive is running, as
noted in the parameter tables in Section 5 of this manual.
CAUTION: Parameter settings and adjustments should be performed by those
familiar with VFD and motor operation characteristics. It is not recommended
for users unfamiliar with these concepts.

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.
Navigation Menu This menu is visible at all times, at a fixed position at the bottom of the screen. The navigation
buttons can be used to switch between different views.
Drive Controls Located to the right of the Navigation Menu, the Drive controls also remain visible regardless of
the active View.
This area will contain Start/Stop buttons when the drive is configured for HMI control, and
Running/Stopped status indicators for other control modes. If the default view is not selected, this
area will also display the output frequency while the Drive is running.
42
Status Indicators
5 - Operation
The general status indicators shown on the Main HMI view give an overview of the Drive status.
Blinking indicators on this screen are designed to draw attention so that error conditions can be
quickly resolved.
Ready This indicator will turn green when the Drive is ready to run. If the Drive is configured for HMI
control, the 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. Refer to Section 7 - Fault Conditions,
for a complete list of Faults, descriptions and solutions.
Once the underlying cause of a fault is resolved, the fault can be cleared by pressing the Reset
button to the left of the fault name. A fault reset can also be performed by a configured digital
input, or by a plant PLC writing to the control register.
Lockout Lockout conditions will prevent the Drive from running. When any lockout occurs, the status
indicator on the right and the Lockouts Warnings Limits button will blink orange. Unlike faults,
lockouts do not latch; the lockout will clear as soon as the underlying condition is resolved, without
a manual reset.
Any lockout condition that occurs while the Drive is running will trigger a fault with the same name.
This fault is latched, so that the lockout cannot be cleared before it is seen by the operator.
Warning Warning conditions are less serious than faults or lockouts, and will not prevent the drive from
running. Some warnings, such as Cell Board Temperature, indicate that a meter is approaching
the trip point, and a fault or lockout is likely to occur. When a warning occurs, the indicator on the
right will display solid yellow. If no lockout is active, the Lockouts Warnings Limits menu button will
also turn yellow.
Limit Limits are triggered when following normal operation would cause the Drive to fault. The Drive will
temporarily ignore some parameter settings, such as Acceleration Ramp Time, in order to run
without faulting. When a limit occurs, the indicator on the right will display solid yellow. If no
lockout is active, the Lockouts Warnings Limits menu button will also turn yellow.
43
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. Check the Event Log for
other conditions that may have already cleared.
NOTE: The HMI will automatically navigate to display the first active lockout,
warning, or limit. If other conditions are active, the additional navigation
buttons at the top of the screen will change color.
44
5 - Operation
Getting the Drive Ready
The ready state indicates that the Drive is ready to run. Until the Drive is ready, all run commands are ignored.
Apply control power to the drive. Control power provides power to run the Drive inverter and the HMI. The HMI
will turn on, and the fans on the inverter cabinet will start.
CAUTION: The drive is not equipped with a power switch of any type. Control and Main power
must be supplied separately by means of appropriate line application equipment or switchgear.
Contact Benshaw for assistance in the selection of applicable devices.
NOTE: If main power (e.g. 4160V nominal) is not applied, a “No DC Bus Fault” will occur. After
main power is applied, press the Reset button next to the fault name on the HMI
NOTE: If a series of question marks are displayed on the HMI over each display field, there is a
failure in connectivity between the Drive inverter and the HMI. Check to ensure proper seating
of the interconnection cables.
The automatic pre-charge sequence of the cell capacitors will initiate on start-up. When the pre-charge is
complete, and any fault or lockout conditions are cleared, the Main view will indicate a ready state.

Operating the Drive
NOTE: Basic parameter settings for your application were set during 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.
commissioning. If changes from those settings are required, select Parameter Settings
from the navigation menu to select and change any parameters required.
1. Navigate to the Main view.
2. Select Setpoint to set the desired speed of the motor in Hz.
NOTE: The allowable range of 0-300Hz presented by the HMI will not always match
parameter settings. If a value is entered outside of the range defined by the Minimum
Frequency and Maximum Frequency Drive parameters, the setpoint will change to the
nearest acceptable value.
3. To start the motor, select Start. The Drive will accelerate according to the Start Mode and
other parameter settings.
4. To stop the motor, select Stop. The Drive will stop the motor according to parameter settings.
NOTE: A negative setpoint is not used to run the Drive in reverse. The Run Reverse
button takes the inverse of the speed setpoint to run at a negative frequency.
NOTE: If reverse capabilities are enabled, select either Run Forward or Run Reverse to
start the motor.
NOTE: The speed setpoint can be adjusted at any time while the drive is running.
46
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:
5 - Operation
DC Pole Voltage
This value reflects voltage stored in the system capacitors.
DC Bus Current
This value reflects the DC Bus current.
Peak Temperature (C)
This value reflects the highest measured temperature from all cell temperature monitors.
Motor Voltage LL (Line-to-Line)
This value reflects the voltage that the drive is sending to the motor.
Phase Currents
This value reflects the individual RMS motor phase currents.
Motor kW
This value reflects the real power on the motor, or “motor load in kW”.
WARNING: Potentially hazardous voltages will remain in the cells until the capacitors are
able to de-energize. Wait at least 30 minutes after main power is removed for the stored
voltages to dissipate if removing the Inverter Cell or Input/Output section covers. Do not
rely solely on the voltage values displayed on the HMI Meter Values screen to determine
if it is safe to remove the covers on the Inverter Cell and Input/Output sections.
47
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.
Ground Fault
This value reflects the ground fault analog input. The Drive is typically configured to trip when the
ground fault input exceeds 5V in either the positive or negative direction.
Motor kW
This value reflects the real power on the motor, or motor load, in kW.
Voltage
This value represents the DC Bus voltage.
Frequency
This graph shows the output frequency of the motor in green, and the frequency command in
blue.
NOTE: The scale of each meter can be changed using the Min and Max buttons below
the graph. An option in the HMI settings can be used to reset all trend ranges to their
default values.
NOTE: These values are displayed in real time only, and not stored within the system.
48
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.
Depending on the parameter, the HMI will display either a numeric value, or a drop-down
selection.
NOTE: Some parameters cannot be changed while the drive is running. The HMI will

selected to view the current value, but the HMI will not allow that value to be changed.
This lock can be adjusted in Settings.
49
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. The Edit button can be used to create and
delete parameter sets, copy all values from the active parameter set, or restore factory default
settings.
NOTE: If no parameter sets have been created, the parameter set selection buttons will

be generated for each motor. If the motors are identical, the values from parameter set 1
can be copied to all other required sets. Any additional changes to parameter settings
should then be copied across each parameter set.
50
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. Section 7 - Parameter Descriptions explains how to
adjust analog I/O settings.
NOTE: The status of this screen only reflects the meter values read by the HMI, and is
not a guarantee that voltage is absent from the I/O wiring. Control power should be
removed before servicing any I/O wiring.
51
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.
NOTE: Yellow or red meter values indicate abnormal conditions in the cell, tied to
warnings and faults. Black text in the Capacitor Voltage columns is normal while the drive
precharges, and should change to green before precharge completes.
When any cell is faulted, the numbered indicator on the left will turn red. Specific faults can then
be viewed by pressing the button around the indicator. Multiple cells can fault at the same time,
and multiple fault conditions can be present in each cell. See Section 8 – Fault Conditions for
information on each type of cell fault.
NOTE: For Drives with 12 or more cells per phase, meters are only displayed for 1 cell at
a time, with a cell selection menu taking up most of the screen.
WARNING: Potentially hazardous voltages will remain in the cells until the capacitors are
able to de-energize. Wait at least 30 minutes after main power is removed for the stored
voltages to dissipate if removing the Inverter Cell or Input/Output section covers. Do not
rely solely on the voltage values displayed on the HMI Meter Values screen to determine
if it is safe to remove the covers on the Inverter Cell and Input/Output sections.
52
5 - Operation
RTD 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.
Digital Output 0 from the RTD Module must be wired to one of the digital inputs of the drive as an
enable signal in order for the Drive to respond to RTD trips.
Configured as a Run Enable will stop the motor according to the programmed Stop Mode
whenever an RTD Trip occurs.
Configured as a Drive Enable will cause the Drive to coast to a stop whenever an RTD Trip
occurs, regardless of Stop Mode setting.
Digital Output 1 of the RTD module indicates when any RTD temperature is above the WARNING
level, and may be interfaced to customer control logic.
Digital Output 2 of the RTD module indicates when any RTD temperature is above the TRIP level,
and may be interfaced to customer control logic.
NOTE: If no RTD module is connected, the warning and trip levels can still be adjusted. This can
cause the HMI to display an RTD trip, but it will have no effect on the operation of the Drive.
53
M2L 3000 Series VFD
Event Log Recent events from the Drive event log can be viewed on the HMI. These events are stored in the
Drive, and are saved after a power cycle. When the Event Log button is pressed on the navigation
menu, the newest events automatically load.
Ten events at a time are displayed on the HMI, with the most recent event at the top of the list.
Use the Next and Previous buttons to navigate between older events, and the Newest button to
return to the most recent events.
Some events store additional diagnostic information, viewable as text. Use the Info button next to
any event to display the info text.
NOTE: If the Next button has been used to view older events, navigating back to the Event Log
will no longer automatically load the newest events. 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.
Available from Benshaw.com.
NOTE: The Event Log can also be configured as a traditional fault log; turn this option on in
Settings to show ten faults at a time, and hide all other events.
54
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.
Show Faults Only
Turn this option ON to remove all non-fault events from the Event Log. This will also change the
text on the navigation menu to Fault Log.
Filter Meters
By default, all meters in the Meter Values view are displayed with a simple Window filter. This
makes the values easier to read, and less sensitive to noise. This filter is not applied to the Output
Frequency, which will always display the raw value from the Drive.
OFF
Meter values are updated as fast as the HMI can read them from the Drive, about five times per
second.
Window Sample Range: 1 - 10
Meters are displayed as an average of the last set of values read from the Drive. The Sample
setting determines the size of the window, and how often the displayed value will update.
Low Pass Sample Range: 1 - 10
Alpha Range: 0.01 - 0.99
Meters are displayed using an internal low pass filter algorithm. A higher Alpha value increases
the response of the filter. The Sample setting determines how often the display is updated with the
new calculated value.
55
M2L 3000 Series VFD
Project Type
There are three configurations of the Drive that require different view options on the HMI. Simple
variations between Drive installations, such as voltage levels and plant interface, do not require
special HMI views. This selection should be set during commissioning, and will not need to
change.
Standard
A single Inverter, controlling a single motor. This is the default option for Drives.
Sync
Synchronous Transfer. Additional Benshaw equipment allows a single inverter to control multiple
motors. Motors, one at a time, can be connected to the Drive, run to match line frequency, and
transferred across the line. All motors in a system can be connected to the line, or one motor can
be run at a variable frequency.
This option adds two new selectable views to the navigation menu, for status information of the
Synchronous Transfer PLC.
Parallel
For the highest horsepower loads, multiple Inverters are connected in parallel to run a single
motor. The HMI then shows data for all inverters, along with combined diagnostic information.
This option adds an additional menu to the HMI, described in a separate manual for Parallel
Drives.
Security
Use this button to open security settings. These settings determine if the Parameter Settings can
be changed from the HMI, and for how long. A User pin can unlock parameters for thirty minutes,
and the Master pin can be used to disable parameter protection.
NOTE: Security settings are only applied to parameters. If the HMI is configured as the
active control source, any user can still access the Start and Stop buttons in the control
area.

Function Group Parameters
FUNCTION-00 (40161) Start Mode Value: 0: Accel
1: Flying Start
2: DC Brake then Start
Start Mode determines what happens when a Start Command is received.
0: Accel, follows the Acceleration Profile (DRIVE-12) from zero speed.
1: Flying Start, determines the speed of a freewheeling motor, and resumes the Acceleration Profile from that point. Used in fan type applications (starting in a spinning
load).
2: DC Brake then Start, the drive applies a DC current to brake the motor before starting a normal acceleration profile from zero speed. Used in fan type applications where
the fan may be freewheeling backward, and needs to be stopped before restarting the
drive.

0: Coast to Stop, disables the output of the drive, allowing the motor to coast to a stop.
1: Decel, follows the Deceleration Profile (DRIVE-14) to zero speed.
2: Coast then DC Brake, the drive allows the motor to coast before applying a DC current to brake the motor. The amount of time coasting is defined by the Coast to Brake
Time (FUNCTION-06).
3: Decel then DC Brake, follows the Deceleration Profile (DRIVE-14) until applying a
DC current to brake the motor. The transition from deceleration to braking occurs when
the drive output reaches the value defined by the Decel to Brake Frequency (FUNCTION-09).
producing braking torque.
When the Start Mode (FUNCTION-00) is set to “DC Brake then Start”, the Starting
Brake Time determines how long the system will apply the DC Brake (a DC current),
used to stop a freewheeling motor before starting. The amount of braking is determined
by the Starting Brake Level (FUNCTION-04).
Brake Level determines how much current the DC Brake will use to stop a freewheeling
motor before starting. This value represents a percentage of the Motor Rated Current
(DRIVE-01), the duration of which is determined by the Starting Brake Time (FUNCTION-03).
Time is used to prevent the drive from being quickly restarted if the motor is still decelerating from a Stop command. Stop Delay Time imposes a delay after the drive determines that the motor has stopped, by monitoring it’s voltage and current, before it can
be started again.

be set to 1.0.
FUNCTION-15 (40130) Motor Thermal Overload
Value: 0 – 99 % Default: 0
Hot/Cold Ratio
The Motor Thermal Overload Hot/Cold Ratio determines the amount of available ther-
mal capacity for a motor that has been running at full load current. The default value of
60% is typical and appropriate for most motors. If required, custom values can be derived from the hot and cold locked rotor times available from most motor manufacturers. A motor that is already hot from previous running will trip the motor overload
sooner than a cold motor.
FUNCTION-16 (40072) Motor Cooling Type Value: 0: Self Cooled
Default: 0
1:-Blower Cooled
Motor Cooling Type defines the type of cooling provided for the motor. Self Cooled indi-
cates that the motor is equipped with shaft-driven cooling, which requires current derating at lower speeds due to less cooling air flow. Blower Cooled indicates that the motor
is equipped with a separately powered cooling device that does not require low speed
derating.

When enabled, the Computer Card monitors communications from a modbus master at
a specified IP address. If the drive is running and the Computer Card does not receive
a poll from the master within the specified time-out period, a fault will occur and the
drive will stop. Set the time-out value and IP address to non-zero values to enable this
feature.
This feature may be used for failsafe operation when some external protective or con
trol device that normally polls the drive malfunctions or losses communication. Rather
than interlocking a status output from that device with the drive’s run command, this
method enables the drive to declare a specific fault to indicate the reason that the drive
stopped

AFN-05 (40144) Skip Frequency Low 3
AFN-06 (40145) Skip Frequency High 3
The Skip Frequency function locks out certain frequencies that can cause resonance in
the driven equipment. The drive will accelerate and decelerate through these frequencies but will not remain at the locked out frequencies. Three different Skip Frequency
ranges can be programmed (AFN-01 through AFN-06).
AFN-07 (40146) Dwell Enable Value: 0: Disabled
The Dwell Function enables the drive to ramp to the programmed Dwell Frequency
(AFN-08), and remain there for the programmed Dwell Time (AFN-09) before continuing the programmed acceleration or deceleration ramp.

When the Dwell function is enabled in AFN-07, this value determines the frequency at
Dwell Time (AFN-09).
AFN-09 (40148) Dwell Time
When the Dwell function is enabled in AFN-07, this value determines the duration of
time that the drive will remain at the frequency programmed in Dwell Frequency (AFN-
08).
AFN-10 (40164) Flying Start Current Level
When the Start Mode (FUNCTION-00) is set to “Flying Start”, a sequence is enabled to
“catch the motor on the fly”. This sequence can be defined in the following steps:
1 - Current Application: The drive applies a low level current to the motor
2 - Frequency Ramp: Beginning at the selected starting (AFN-14) fre-
quency, the drive ramps output frequency down until the speed of the motor
is matched
3 - Voltage Adjust: The drive sets the voltage to the appropriate level based
on the frequency determined in Step 2.
Once this sequence is complete, the drive then accelerates along the programmed acceleration profile.
Flying Start Current Level defines the low level current output used to begin the Flying
Start sequence Step 1. While in Flying Start sequence Step 2, the output voltage is reduced as necessary to maintain current below the Flying Start Current Level.
AFN-11 (40165) Flying Start Current
Flying Start Current Application Time defines the length of time for Step 1 of the Flying
Start sequence. The drive applies the Flying Start Current Level (AFN-10) before continuing with the flying start sequence.

Refer to I/O-40 through I/O 44 (AI #1) for I/O-44 through I/O-71 (AI #2 through AI#8) range and parameters.
The Process and Input Value Low/High parameters define the scaling for each of the Analog Inputs.
The “Input” parameters describe the electrical signal going into the analog input. If it is a
4-20mA type analog input, the units are in milliamps. If it is a 0-10V or -10 to 10V type
analog input, the units are in volts.
The “Process” parameters describe what that electrical signal is translated to. These parameters are entered as a percentage of the full scale process variable. The process variable is determined by the Analog Input Function selection.
For example, if Speed Reference is selected for the Analog Input Function, then the process variable is percentage of the Maximum Frequency parameter (DRIVE-10).
For scaling to the fullest, set Process Low to 0% and Process High to 100%, then set Input Low to the minimum electrical signal, and Input High to the maximum electrical signal.
For scaling to a different gain, or to incorporate an offset, adjust these four parameters as
necessary.

8 – Fault Conditions
8 – Fault Conditions
This section contains a Fault Condition Table which provide descriptions, along with a suggested course of action, for each
Fault condition possible in the M2L 3000 drive.
Table Key
Fault Codes Each Fault has a unique code.
Fault Displayed Fault Displayed represents what will be displayed to the user on the HMI, at the top por-
tion of the Main Screen.
Reaction Type Different faults result in the drive reacting in different ways. In some fault conditions, the
drive immediately stops outputting voltage and opens the main contactor, resulting in the
motor coasting to a stop. For others, it can follow the deceleration ramp profile to a stop.
For those that stop immediately, some assert a shunt trip. Some faults require that the
control power be cycled in order to reset them. The Reaction Type column codes are defined as:
C The drive stops voltage output immediately, and the motor/load coasts to a
stop
D The motor/load decelerates to a stop following the deceleration ramp profile
S The drive asserts a shunt trip fail safe relay
F Requires a control power cycle to reset
Description The Description column provides basic information regarding what has occurred within
the system when a specific fault occurs.
Course of Action This column contains the recommended actions that can be taken in the field by on-site
technicians to remedy the fault condition. If the condition persists, contact Benshaw for
further assistance, or to arrange on-site repair.
WARNING: At any time the system is energized with Medium Voltage
power, apply appropriate personal protective equipment (PPE) and follow
safe electrical work practices when operating or working near the system.
See NFPA 70E.
Cabinet Fault Limit: <10kA @ 10 Cycles
Min Arc Boundary: 40 Inches
Recommended Min. PPE: #1 at > 40 inches
WARNING: Only qualified personnel familiar with the use and hazards of
medium voltage equipment are to perform work described in this set of instructions
WARNING: Before performing visual inspections, tests, or maintenance
on the equipment, disconnect all sources of electric power. Assume that
circuits are live until completely de-energized, tested, and tagged.
Pay particular attention to the design of the power system. Consider all
sources of power, including the possibility of backfeeding.
Use a properly rated voltage sensing device to confirm that the power is
fully removed.
93
M2L 3000 Series VFD
WARNING: Always perform applicable lock-out/tag-out procedures (either
general or site-specific) before performing any maintenance or troubleshooting on the system.
WARNING: To avoid potentially lethal levels of both AC and DC voltages,
do not remove the cover to access the Input/Output section of the Inverter
while the Inverter is energized.
WARNING: Potentially hazardous voltages will remain in the cells until the
capacitors are able to de-energize. Wait at least 30 minutes after main
power is removed for the stored voltages to dissipate if removing the Inverter Cell or Input/Output section covers. Do not rely solely on the voltage values displayed on the HMI Meter Values screen to determine if it is
safe to remove the covers on the Inverter Cell and Input/Output sections.
WARNING: The Control section contains 240V control power when active.
The Control section does not contain medium voltage levels supplied from
the mains, and can be carefully accessed by qualified personnel while medium voltage from the AC mains is applied to the system.
WARNING: Replace all devices, doors, and covers before applying power
to this equipment.
CAUTION: The contacts on the supplied shunt trip relay must be connected to the feed breaker. The shunt trip is used to protect the drive and
motor from damage in the event of certain fault conditions.
CAUTION: Special care must be taken with the cover over the Control
section and all panels. A ground wire is attached to the inside of that cover
that ties it to ground potential. It is important that the connection integrity
of this wire be maintained to avoid compromising the immunity of the Inverter to Electromagnetic Interference (EMI.)
CAUTION: Always be aware of electrostatic discharge (ESD) when working near or touching components inside the drive. Handling of components
sensitive to ESD should be done by qualified personnel only, familiar with
ESD mitigation techniques.
CAUTION: Parameter settings and adjustments should be performed by
those familiar with VFD and motor operation characteristics. It is not recommended for users unfamiliar with these concepts.

Occurs when the motor thermal
overload I2T calculation exceeds 100%.
Parameters that can affect the motor
thermal overload I2T calculation
exceeding 100% include:
Motor Rated Current (DRIVE-
01)
Motor Thermal Overload Level
(FUNCTION-11)
Motor Thermal Overload Time
(FUNCTION-12)
Motor Service Factor (FUNC-
TION-14)
Motor Cooling Type (FUNC-
TION-16).
Occurs when the inverter thermal
overload I2T calculation exceeds 100%.
Occurs when the drive is running and
the DC bus voltage drops 15% below
the expected nominal level.
Verify that the parameters are set
appropriately for the motor, and that the
motor is not operating beyond its capability.
The overload protection can be relaxed by
setting either the Motor Thermal Overload
Level (FUNCTION-11) higher, or setting the
Motor Thermal Overload Time (FUNCTION-
12) longer. It may even be defeated by
turning off the Motor Thermal Overload
Enable (FUNCTION-10). Doing either of
these risks damaging the motor.

If this is caused by a seasonal drop in the
utility voltage, the taps on the primary side of
the front end transformer can be moved
down 5% to boost its output voltage by 5%.
Front end transformers supplied by Benshaw
have taps for -5%, 0% and +5%.
This condition could also be caused by the
loss of one or more fuses or diodes in the
front end rectifier.

Occurs when the drive is running and
the calculated phase current imbalance
exceeds the level set in the Output

by the Output Phase Loss Trip Time
parameter (FUNCTION-29).
Occurs when the drive is running and
detects the loss of an input phase, or a
blown fuse or damaged rectifier diode in
the rectifier section.
This condition could be caused by:
current imbalances that occur at the
beginning of a ramp
a loose or open power wiring con-
nection
a damaged motor
Set the Output Phase Loss Enable
(FUNCTION-27) parameter to Disabled, and
observed the three phase currents on the
Meter Trending screen while the motor is
starting. If the currents are only imbalanced
at the beginning of the ramp, extend the
Output Phase Loss Trip Time (FUNCTION-
29) parameter, and set the Output Phase
Loss Enable (FUNCTION-27) parameter
back to Enabled.
Check power wiring connections between the
inverter and the motor.
This condition could be caused by:
loss of one input phase from the
power source (blown supply fuse,
loss of phase from the utility source

It is also possible that the motor current
could have dropped out if the drive was not
supplying enough voltage. In this case, the
motor would either stop spinning, or spin
slowly before the fault occurs. Verify that the
Motor Rated Voltage (DRIVE-02) parameter
matches the motor nameplate.

Precharge
timeout fault
Reaction
Type
Description Course of Action
The fault is triggered if the cell
capacitors do not charge to 90% of
nominal within 30 seconds of first
applying control power, or after resetting
of a fault.
Verify that all upstream switchgear for the
medium voltage supply to the drive is closed.
Reset the fault, then monitor capacitor
voltages on the Cell Status screen as the
drive attempts to precharge. If there is only
one cell with capacitors that are not charging
like the others, replace that cell.
If medium voltage is available to the drive,
and none of the cell capacitors charge, then
the Precharge Board is not closing its
precharge relays. The Precharge Board
receives the command to close its relays
from Digital Output 1 on the Remote IO block
by a 120VAC signal on wire 50.
Verify that Digital Output 1 is receiv-
ing 120VAC on wire 6B
Verify that Digital Output 1 closes
during precharge, and supplies
120VAC on wire 50
If the LED on Digital Output 1 indi-
cates that it is closed, but does not
supply 120VAC on wire 50, the digital output may have failed. Replace
the digital output module.
If Digital Output 1 is functioning normally, the
Precharge Board may have failed, or there
may be a loose connection to the Precharge
Board. Be sure to remove Medium Voltage
and allow time for the cell capacitors to
discharge before accessing the Precharge
Board.
Verify that wires 50 and 7 are se-
curely connected to the Precharge
Board
Verify that the thick white wires are
securely connected to the main contactor tabs and studs on the Precharge Board.
If all wires are securely connected,
the Precharge Board may have
failed. Replace the Precharge Board.
If medium voltage is available to the drive,
the drive has multiple Precharge Boards in
parallel, and all of the cells charge to a value
that is only a fraction of the expected voltage
before the Precharge timeout fault occurs,
one of the multiple precharge circuits may
have a loose connection, or failed
component. Follow the same troubleshooting
