2-2 Selecting Other System Components
Interface Cables
Standard Allen-Bradley motor power and encoder feedback cables, as
well as communications cables, are available to complete your motion
control system and provide reliable, trouble free start-up. Refer to
“Options and Accessories” on page A-1 for optional equipment. Use
of these cables is required for compliance to the European
Electromagnetic Compatibility (EMC) Directive and to protect your
warranty rights.
ULTRA 200 Series Features Stand-alone Design
A single unit fully encloses all electronics, including both the power
supply and a built-in shunt regulator. An external transformer is not
required on the main power line. All connectors and indicators are
accessible and clearly marked on the front panel.
High Performance Microcontroller Technology
Dual microcontrollers perform all digital current, velocity and
position loop calculations as well as the motor commutation
calculation.
IPM Technology
IPM (Intelligent Power Module) technology in the output stage
provides a high frequency, digital PWM (Pulse Width Modulation)
sine wave that controls the current loop, including overcurrent, short
circuit and overtemperature protection.
Analog and Digital Interfaces
All ULTRA 200 Series drives allow the user to select one of the
following analog or digital command interfaces:
● ±10 Volt analog interface – position, velocity or torque control
● Presets (from one to eight binary inputs) – torque or velocity
control
● Quadrature encoder digital interface – electronic gearing position
follower
● Step/Direction digital interface – position control
● CW/CCW (step up/step down) interface – position control
● Indexing (available only on 1398-DDM-010X, 1398-DDM-020X,
1398-DDM-030X, 1398-DDM-075X and 1398-DDM-150X.
Encoder Control
A single, motor mounted encoder provides complete commutation
information and velocity feedback.
