ii 1000 Series / Guide to Installation, Troubleshooting, and Maintenance
General Precautions
!
Attention
Only qualified personnel with the proper skills, instruction, and familiarity
with the drive and its applications should install, start up, operate,
troubleshoot, and maintain the drive. You must be familiar with the
electrical and mechanical components of the system to perform the
procedures outlined in this manual. Failure to comply may result in personal
injury, death, and/or equipment damage.
!
Attention
Failure to take proper precautions for electrical hazard could cause injury or
death.
!
Attention
Failure to follow industry safety standards and instructions in this manual
could damage the drive and void the manufacturer’s warranty.
!
Attention
The drive may be sensitive to electrostatic discharge. Static precautions are
required when servicing or repairing the unit.
!
Attention
If an aluminum electrolytic capacitor in the drive fails from a build-up of
internal pressure, a safety vent will operate, spraying electrolyte vapor from
the capacitor. If a capacitor vents, avoid contact with the liquid, avoid
inhaling the vapors, and ventilate the area. If your skin comes in contact
with the electrolyte, flush it immediately with cold water. If electrolyte gets
in your eyes, immediately remove any contact lenses and flush the open
eyes with plenty of clean water. If electrolyte is ingested, dilute it by
drinking warm water and seek immediate medical attention.
!
Attention
Drives are intended for fixed, permanent connection to earthed three-phase
supply mains. Use of EMC filters along with the equipment will increase
leakage current in the protective conductor and may affect compatibility
with residual-current-operated protective devices.
!
Attention
The drive provides solid-state motor overload protection. The level of
protection is dependent upon the rating of the unit (given in Table 2-2) as
well as the software overload specified by the user. Please refer to the
application documentation for instructions on adjusting the overload.

Safety Information iii
Installation Precautions
!
Attention
An incorrectly installed or operated drive can result in damage to the
equipment it controls. Make certain installation and operating specifications
are followed.
!
Attention
To provide protection against electrical shock, drives must be mounted in
an enclosure meeting at least the requirements of Protective Type IP20 (or
NEMA equivalent) according to EN60529 and with top surfaces meeting at
least the requirements of IP40 (or NEMA equivalent). It is recommended
that a key or tool be required to open the enclosure and that enclosure doors
be interlocked with the electrical supply disconnect.
!
Attention
The drive and associated equipment must be properly earth grounded.
!
Attention
Any site insulation tests must be performed before making electrical
connections to the drive.
!
Attention
The drive is not equipped with a supply-disconnecting device. An external
supply-disconnecting device must be provided to isolate incoming electrical
supplies during installation and maintenance work. This device should
comply with the requirements of EN 60204-1 as well as all applicable
national and local regulations.
Application Precautions
!
Attention
Emergency stop devices shall be located at each operator control station and
at other operating stations where emergency stop may be required. Control
inputs and keypad motor-control functions do not generate an emergency
stop of the motor and do not remove power that can cause hazardous
conditions. Regardless of the operating state, the drive’s motor output
terminals may be at dangerous voltage levels whenever input power is
applied and the bus is charged.

iv 1000 Series / Guide to Installation, Troubleshooting, and Maintenance
!
Attention
Drive functionality depends upon the application software installed. Some
application software offers automatic restart functions that allow the unit to
reset and resume operation after a fault. These functions must not be
enabled when hazardous conditions might arise from such action. Certain
features may present additional hazardous situations. Refer to the associated
application documentation for further safety information.
Service Precautions
!
Attention
Always disconnect and lock out all electrical supplies before working on the
drive or associated equipment. Do this before touching any electrical or
mechanical components associated with the drive application.
!
Attention
High voltage may be present even when all electrical power supplies are
disconnected. After switching off electrical power, wait at least 15 minutes
for bus circuit capacitors to discharge before working on the drive or
associated equipment. Use an appropriate voltmeter to further verify that
capacitors are discharged before beginning work. Do not rely exclusively on
the bus voltage indicator. Dangerous voltage levels may remain even when
the indicator is off.
!
Attention
High voltage may be present at the motor output terminals (U, V, W)
whenever input power is applied, regardless of whether the motor is
moving or not.
!
Attention
Before energizing the motor, verify that there are no loose components
associated with the drive train and that motor motion will not result in
injury or damage to the equipment.
Safe Service Practices
Follow industry-recognized safety procedures:

Product Overview 2-3
2.3 Family Overview
The 1000 family of AC drives provides digital flux vector control of ordinary three-phase
AC motors. The drives combine the latest insulated-gate-bipolar-transistor (IGBT), pulse-
width modulation (PWM), and digital signal processor (DSP) technologies with digital-
current-regulator (DCR) or digital-space-vector (DSV) control to deliver optimum motor
performance, complete programmability, and simplicity of operation. Variable-frequency
drive (VFD) operation is also available for cost-effective control of motor speed in
simple applications.
The complete family is comprised of the 1100, 1105, 1110, 1120, 1130, 1200, and 1230
series of variable-frequency drives as well as the 1140 variable-voltage drive. These
drives share a common architecture that provides a high degree of internal consistency.
By combining this core drive topology with unique input sections, the 1000 family
furnishes flexible, efficient, and cost-effective solutions to a variety of application needs.
Table 2-1 summarizes the various models within the family. The 1140 is described in a
separate publication.

2.3.1 Features
Performance Flexibility
The 1000 family accommodates a broad range of performance requirements. Units may
be configured for constant-torque operation for heavy-duty cyclic loads, variable-torque
operation for medium-duty requirements, or extended-torque operation for centrifugal
loads such as fans and pumps. The drive operates in a transducerless vector control mode
that does not require a feedback device and produces full torque to base speed with full
starting torque. For demanding applications, an incremental encoder or resolver interface
can be added for precise position, velocity, and torque regulation and improved dynamic
performance. Dual- and triple-encoder interfaces are also available for position-following
and dual-transducer applications. Variable-frequency control is alternately available for
applications that do not require critical velocity or torque control.

2-4 1000 Series / Guide to Installation, Troubleshooting, and Maintenance
Motor-Independent Design
The 1000 family drives operate any standard- or inverter-duty AC induction or
synchronous motor, making it ideal for retrofits and new applications alike. A unique,
proprietary digital current regulator (DCR) tunes the drive continuously in real time,
eliminating the usual current-loop tuning process required by conventional drives. Digital
space vector (DSV) control can be selected for reduced motor noise and low current
ripple.
Auto Tuning
Once routine electrical connections have been made, simple-to-use auto-tuning features
adjust virtually all motor- and load-dependent parameters. No motor maps are required.
Simply enter basic motor information from the nameplate, and the advanced setup
routines do the rest. The drive is completely tuned within minutes.
Control Options
Numerous control and interface options are available. The 16 MHz control module
provides variable-frequency drive (VFD) control for simple applications. The 20 MHz
and 40 MHz control modules are available in digital-current-regulator (DCR) and digital-
space-vector (DSV) versions. The 100 MHz, 270 MHz, and Compact 100 MHz control
modules provide for VFD, DCR, and DSV control. The Compact 150 MHz control
module provides VFD and DSV control. Each control module provides digital and analog
inputs and outputs as well as asynchronous serial communication capabilities. The 20
MHz, 40 MHz, 100 MHz, 270 MHz, and Compact 100 MHz modules also provide
synchronous serial communication capabilities. The 100 MHz and 270 MHz modules
include provision for an optional Anybus®module for communication using a variety of
industry-standard protocols, while the 100 MHz, 270 MHz, and the Compact 100 MHz
modules include provision(s) for a MaxStream™module for wireless communication.
Depending upon the control module, drives can accept motor and/or machine feedback
with a single, dual, or triple incremental encoder interface, a resolver interface, or
resolver and encoder interfaces. An optional analog interface module is also available for
expanding the analog I/O capabilities of a drive. One of three keypad/display units is
available, depending upon the application.
Application Software
A wide variety of software options is available to tailor a drive to its application, from a
fully featured velocity/torque control for general purposes to a host of powerful programs
pre-engineered for specific applications. Customization is possible with many programs
using UEdit™, a Windows-based programming tool that allows users extend an
application using IEC 1131 standard ladder diagrams and function blocks.
Braking Options
The 1000 family offers both dynamic and regenerative braking options. A dynamic
braking IGBT allows motor braking energy to be dissipated in an external resistor. This
dynamic braking control is included as standard on all 1120 drives and smaller 1105 and
1200 drives. It is optional on larger 1105 and 1200 drives and all 1100 and 1110 drives.
Appropriately sized external braking resistors are required. The 1130 and 1230 line-
regenerative drives provide true four-quadrant control without requiring dynamic
braking. Energy generated by stopping the motor and load is put back onto the power grid
rather than wasted as heat in a resistor.

Product Overview 2-5
Digital Setup, Easy Operation
A keypad and liquid crystal display provide a simple interface for setting and viewing
operating parameters and diagnostics. All controller settings are made digitally for
precision and repeatability. Readouts and fault messages are displayed in readily
understandable language. A graphical display option provides on-board oscilloscope-type
viewing of drive and system parameters.
Multiaxis Operation
A built-in high-speed synchronous communication port allows the motion of multiple
slave drives to be precisely coordinated. With optional master/slave software, the velocity
ratio and position phasing of the drives can also be controlled. Multiple motors can be
operated in parallel from a single drive using optional variable-frequency control.
Power Quality
A built-in link choke on the 1100, 1105, and 1110 drives and the unique low-capacitance
design of the 1200 provides near-unity overall power factor and low harmonic line
currents at all motor speeds. High-power 1100, 1105, and 1200 drives also offer a six-
phase (twelve-pulse) configuration for further minimizing line harmonics in critical
applications. The 1130 and 1230 line-regenerative drives provide near-unity power factor
for both motoring- and braking-type loads by using an IGBT bridge to control the flow of
power into and out of the drive.
Protection and Advanced Diagnostics
Drives monitor their operating conditions and provide a comprehensive set of overload,
short circuit, and other electronic protective features to ensure safe, reliable operation.
Faults indications are displayed in plain language. A log maintains a history of fault
occurrences and externally triggered events.
Serial Connectivity
An RS-422/485 serial interface is provided for connecting a drive to a process controller,
communication network, or programmable controller. A variety of popular
communication protocols is available. The 100 MHz and 270 MHz modules also accept
an Anybus®module with numerous industry-standard protocol options, and the 100 MHz,
270 MHz, and Compact 100 MHz modules accept MaxStream module(s) for wireless

Packaging
Compact and rugged, drives are available either enclosed or as an open chassis for
mounting inside an enclosure. Both versions can be foot-mounted to a wall or subplate or
flange-mounted through a cutout to dissipate heat outside an enclosure. Standard
packaged systems are also available that incorporate additional components within an
enclosure.

2.3.2 Drive Architecture
The general function of the drive is to convert a fixed voltage and frequency from an
electrical power source into a variable voltage and frequency for controlling an AC
motor. The basic architecture of the 1100, 1105, and 1110 drives is shown in Figure 2-2,
that of the 1120 drive in Figure 2-3, that of the 1130 and 1230 drives in Figure 2-4, and
that of the 1200 in Figure 2-5.
A rectifier section is used on the 1100, 1105, 1110, and 1200 drives to convert the fixed
AC line voltage into a DC bus voltage. The 1120 is a modular design intended for
operating a number of units from a common DC bus. Low-power drives use a diode
rectifier and resistors to charge the bus capacitors, which is then bypassed by a contact
once the bus is up to full voltage. Medium- and high-power drives use silicon-controlled
rectifiers (SCRs) to control the charging of the bus capacitors. High-power drives provide
for optional twelve-pulse (six-phase) connection of the input to reduce harmonic currents.
The 1110 drive is designed for single-phase operation using two, rather than three, AC
line voltage terminals. A rectifier control coordinates the charging of the bus.
A link choke and bus capacitors in the 1100, 1105, and 1110 drives form a filter that
smoothes the output of the rectifier section into a steady DC voltage. An optional
dynamic brake device on these units allows regenerative energy from the load to be
dissipated in an external resistor when the drive is braking. The link choke and dynamic
brake device are normally part of the converter supplying the DC bus to 1120 units.
A converter section is used on the 1130 and 1230 drives to regulate power flow between
the AC line and DC bus. The converter uses an insulated gate bipolar transistor (IGBT)
bridge to rectify the AC line voltage into a DC bus voltage. This section also regenerates
energy from the DC bus to the AC line when the drive is braking.
An inverter section consisting of six insulated gate bipolar transistors (IGBTs) is used to
power an AC motor. This section can produce sine-wave motor voltages and currents of
any desired amplitude by rapidly switching the IGBTs using a technique called pulse-
width modulation (PWM). A gate driver is used to pass switching signals from the drive
controller to the IGBTs.
Overall operation of the unit is regulated by a drive control that incorporates a digital
signal processor (DSP) and a digital current regulator (DCR) or digital space vector
(DSV) control. This high-speed digital control uses both voltage and current feedback to
regulate the output to the motor. Optional encoder and resolver interfaces are available to
provide closed-loop control of motor velocity and/or position. A dual encoder option is
available to slave the motor to other sections of a machine or to reduce machine
resonance using dual transducer control. Variable-frequency drive (VFD) operation is an
option for controlling AC motors in simple applications.
A keypad and displayon the control module provide access to operating and setup
parameters. The control module also provides analog and digital inputs that can be used
as input to and output from the drive. Serial communication channels are also available
for connecting drives to process controllers, communication networks, programmable
controllers, or personal computers.
