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.
