Chapter 2

PowerFlex 7000 Overview

The PowerFlex 7000 is a general purpose, stand-alone, medium voltage drive that
controls speed, torque, direction, starting and stopping of standard asynchronous
or synchronous AC motors. It works on numerous standard and specialty
applications such as fans, pumps, compressors, mixers, conveyors, kilns, fan­pumps, and test stands in industries such as petrochemical, cement, mining and
metals, forest products, power generation, and water/waste water.

The PowerFlex 7000 meets most common standards from the National Electrical
Code (NEC), International Electrotechnical Commission (IEC), National
Electrical Manufacturers Association (NEMA), Underwriters Laboratories
(UL), and Canadian Standards Association (CSA). It is available with the world’s
most common supply voltages at medium voltage, from 2400...6600V.

Topology

The design focus is on high reliability, ease of use, and lower total cost of
ownership.

The PowerFlex 7000 uses a Pulse Width Modulated (PWM) – Current Source
Inverter (CSI) topology. This topology applies to a wide voltage and power
range. The power semiconductor switches used are easy-to-series for any medium
voltage level. Semiconductor fuses are not required for the power structure due to
the current limiting DC link inductor.

With 6500V PIV rated power semiconductor devices, the number of inverter
components is minimal. For example, only six inverter switching devices are
required at 2400V, 12 at 3300...4160V, and 18 at 6600V.

The PowerFlex 7000 also provides inherent regenerative braking for applications
where the load is overhauling the motor (e.g. downhill conveyors, etc.), or where
high inertia loads (e.g. fans, etc.) are quickly slowed down. The drive uses
Symmetrical Gate Commutated Thyristors (SGCTs) for machine converter
switches, SGCTs (for Active Front-end [AFE] rectifier configurations) for the
line converter switches and Silicon-controlled Rectifiers (SCRs) (for 18 Pulse
rectifier configurations).

The PowerFlex 7000 provides a selectable option for enhanced torque control
capabilities and increased dynamic control performance. This High Performance
Torque Control (HPTC) feature delivers 100% torque at zero speed and
provides torque control through zero speed with smooth direction transition.

Rockwell Automation Publication 7000-UM202B-EN-P - June 2014 13

Chapter 2 PowerFlex 7000 Overview

Rectifier Designs

Configurations

The PowerFlex 7000 offers three rectifier configurations for "B" Frame drives:

• Direct-to-Drive (AFE rectifier with integral line reactor and Common
Mode Choke)

• AFE rectifier with separate isolation transformer

• 18 Pulse rectifier with separate isolation transformer

Direct-to-Drive

Direct-to-DriveTM technology does not require an isolation transformer or
multiple rectifier bridges as in Voltage Source Inverter (VSI) topologies offered
by others. The approach is completely different. Instead of multiple
uncontrolled rectifiers, a single AFE rectifier bridge is supplied. The rectifier
semiconductors used are SGCTs. Unlike the diodes used in VSI rectifier bridges,
SGCTs are turned on and off by a gating signal. A PWM gating algorithm
controls the firing of the rectifier devices, very similar to the control philosophy
of the inverter. The gating algorithm uses a specific 42 pulse switching pattern
(Figure 1
and 11th harmonic orders.

Figure 1 - Typical PWM switching pattern, line voltage waveform

) called Selective Harmonic Elimination (SHE) to mitigate the 5th, 7th,

A small integral line reactor and capacitor addresses the high harmonic orders
(13th and above) and provides virtually sinusoidal input voltage and current
waveforms back to the distribution system. This delivers excellent line-side
harmonic and power factor performance to meet IEEE 519-1992 requirements
and other global harmonic standards in virtually all cases, while still providing a
simple, robust power structure that maximizes uptime by minimizing the number
of discrete components and the number of interconnections required.

A Common Mode Choke (CMC) mitigates the common mode voltage seen at
the motor terminals, so standard (non-inverter duty rated) motors and motor
cables can be used, making this technology ideal for retrofitting existing motor
applications.

AFE Rectifier with Separate Isolation Transformer

For applications when the line voltage is higher than the motor voltage, a
transformer is required for voltage matching. In this case, providing an AFE
rectifier with a separate isolation transformer is ideal (indoor and outdoor
transformer versions are offered). The isolation transformer provides the input
impedance (replaces the requirement for an integral line reactor) and addresses
the common mode voltage (replaces the requirement for a CMC that is supplied
in the Direct-to-Drive rectifier configuration). However, the AFE rectifier, its
operation, and advantages are the same as the Direct-to-Drive configuration.

18 Pulse Rectifier with Separate Isolation Transformer

For high power constant torque applications and/or when the line voltage is
higher than the motor voltage, a transformer is required for voltage matching
(indoor and outdoor transformer options are available). The 18 Pulse rectifier
uses SCRs instead of the SGCTs used for an AFE rectifier. When used for high
power constant torque applications, the 18 Pulse rectifier has lower losses than
the AFE rectifier, making it ideal for the highest power requirements. The 18
Pulse isolation transformer provides the required input impedance and addresses
common mode voltage just like the separate isolation transformer used with the
AFE rectifier. However, instead of a PWM rectifier switching pattern and a
single rectifier bridge, the 18 Pulse configuration mitigates line side harmonics
through harmonic current cancellation in the isolation transformer phase shifted
secondary windings. The inverter is the same configuration for all available
rectifier options.

Cooling Technology

These VFDs are supplied with heat sinks for most configurations and heat pipes
for the highest-power AFE configurations. While both configurations draw heat
away from the semiconductors, heat pipes are bigger, more efficient, and require
larger fans and airflow.

Information and graphics in this manual show both configurations.

Motor Compatibility

The PowerFlex 7000 achieves near-sinusoidal current and voltage waveforms to
the motor, resulting in no significant additional heating or insulation stress.
Temperature rise in the motor connected to the VFD is typically 3 °C (5.5 °F)
higher compared to across-the-line operation. Voltage waveform has dv/dt of less
than 50 V/

µs. The peak voltage across the motor insulation is the rated motor

RMS voltage divided by 0.707.

Reflected wave and dv/dt issues often associated with voltage source inverter
(VSI) drives are a non-issue with the PowerFlex 7000. Figure 5

shows typical
motor waveforms. The drive uses a selective harmonic elimination (SHE) pattern
in the inverter to eliminate major order harmonics, plus a small output capacitor
(integral to the drive) to eliminate harmonics at higher speeds.

Standard motors are compatible without de-rating, even on retrofit applications.

Motor cable distance is virtually unlimited. Rockwell Automation has tested this
technology for controlling motors up to 15 km (9.3 mi) away from the drive.

Operator Interface

The HMI Interface Board is an HMI-enabling device for the PowerFlex 7000
drive. It allows the user to acquire all the necessary executable tools,
documentation and reports required to commission, troubleshoot and maintain
the drive.

Via the HMI Interface Board, the user can choose the style and size of the desired
Windows-based operator terminal to interact with the drive (e.g. PanelView CE
terminal, laptop, or desktop computer). The HMI Interface Board removes past
issues with compatibility between the drive and configuration tools, as all the
necessary tools are acquired from the drive.

The HMI Interface Board is well suited for applications that require remote
placement of the operator terminal and remote maintenance.

Figure 15 - Operator Interface

Basic Configurations

There are three basic configurations for the HMI.

Remote-mounted HMI

The HMI is not mounted in the traditional location on the low voltage door of
the Variable Frequency Drive (VFD). A remote mounting plate, complete with
E-Stop push button, and HMI is supplied loose for the customer to mount
wherever desired. The HMI connects to the VFD via a hardwired Ethernet cable.
There is no significant functional distance limitation.

Rockwell Automation Publication 7000-UM202B-EN-P - June 2014 21

Chapter 2 PowerFlex 7000 Overview

This is ideal for non-PLC users wanting to control and monitor remotely (e.g. at
the driven machine, control room, etc.). Also ideal for customers having policies
in place to control access to medium voltage equipment and the associated
requirements of PPE when using the operator interface at the VFD, etc.

Locally-mounted HMI

Similar to the previously offered PanelView 550, the HMI is mounted on the LV
door of the VFD. There is also a service access port (RJ-45 connector) on the LV
door.

No HMI supplied

A service access port (RJ-45 connector) is located on the LV door of the VFD.
Customers use their own laptop as the HMI. All programs required to use the
laptop as the HMI are stored in the VFD. Their laptop is connected to the VFD
via a hardwired Ethernet cable, when required. This is ideal for unmanned sites,
where a dedicated HMI is not required.

Component Definition and Maintenance

This section provides an overview of the control components and cabling of your
PowerFlex 7000 “B” Frame drive. It also details a number of regular or recurring
maintenance tasks that will keep your drive in peak operating condition.

The following illustrations identify the control components and cabling of your
drives. Where appropriate, separate diagrams and instructions are available for
both the heat sink and the heat pipe “B” Frame models.

For information regarding power wiring and cabling connections (as might be
necessary for routine maintenance) refer to the PowerFlex 7000 “B” Frame
Installation Manual (7000-IN007_-EN-P

).

Control Power Off Tests

Perform the following checks before applying control power to the drive.
Rockwell Automation recommends that you complete these checks in the
sequence they are presented here.

This section is also available in the PowerFlex “B” Frame Commissioning Guide
(7000-IN006_-EN-P
drive testing.

); refer to that document for additional information on

Interlocking

When the input contactor option is purchased, a key interlock is provided to
prevent access to the medium voltage compartments of the drive unless the input
isolation switch is locked in the open position.

Where the input switching device is provided by others, Rockwell Automation
will provide a key interlock on the medium voltage compartment of the drive,
and a matching interlock for installation by others on the upstream device. The
interlock shall be installed in a manner that ensures the power to the drive is off
and the drive is electrically isolated whenever the key is freed.

Although Key interlocks shipped with all medium voltage equipment are aligned
in the factory, they often move out of position during shipping or are often
misaligned when the cabinet is set down on an uneven floor. The following
instructions will assist the field engineers in quickly and accurately aligning the
deadbolt key interlock with its counterpart.

Rockwell Automation Publication 7000-UM202B-EN-P - June 2014 23

Chapter 3 Component Definition and Maintenance

ATT EN TI ON : Servicing energized industrial control equipment can be

hazardous. Severe injury or death can result from electrical shock, burn, or
unintended actuation of control equipment. Hazardous voltages may exist in
the cabinet even with the circuit breaker in the off position. Recommended
practice is to disconnect or lock out control equipment from power sources, and
confirm discharge of stored energy in capacitors. If it is necessary to work in the
vicinity of energized equipment, the safety related work practices of NFPA 70E,
Electrical Safety requirements for Employee Work places, must be followed.

Figure 16 - Deadbolt assembly mounted to door

1. Lock out and isolate the drive from medium voltage. Verify with a hot
stick that there is no medium voltage present.

2. Determine that the key interlock is correctly aligned by securely bolting
the medium voltage doors of the cabinet closed and removing the key from
the lock. The key should turn easily; if any force is required to turn the key,
the deadbolt alignment requires adjustment.

3. Open the doors of the cabinet and inspect the key assembly. Place high
visibility grease on the pins of the deadbolt counterpart. The factory
recommends using yellow torque sealant, however if it is unavailable
almost any grease will do (Figure 17

).

24 Rockwell Automation Publication 7000-UM202B-EN-P - June 2014

Component Definition and Maintenance Chapter 3

Figure 17 - Deadbolt counterpart mounted to cabinet

4. Bolt the cabinet door closed so the pins on the dead bolt counterpart make
contact with the deadbolt assembly. Doing so should leave two marks of
torque sealant or grease on the assembly where the pins made contact (see

Figure 16 on page 24

).

Control / Cabling Cabinet Components

5. Slightly loosen the adjustment bolts on the counterpart and make the
necessary movements on the counterpart to ensure that the pins align with
the landing plates on the deadbolt assembly. As the amount of counterpart
movement required is an estimate, it may take a couple attempts to
properly align the assembly.

6. Clean the torque seal/grease from the key interlock once finished aligning
the counterpart.

Once properly aligned, the key should turn freely when the cabinet door is fully
bolted shut. If the key does not function when the door is tightly bolted closed,
adjustments will have to be made to the depth of the counterpart. This can be
done by adding shims on the landing plate where the counterpart is mounted.
