2 Safety Precautions
2.1 Definitions and Symbols
The following terms and symbols are used in this documentation
and also appear on C-Drive Series Amplifiers where safety-related
issues occur.
2.1.1 Protective Earth (Ground)
Figure 1: Protective Earth (Ground) Symbol
The Protective Earth (Ground) Symbol in the figure above appears
on labels affixed to the C-Drive Series Amplifiers, and this symbol
identifies terminal which is intended for connection to an external
(ground) conductor for protection against electric shock in case of
a fault, or the terminal of a protective earth (ground) electrode.
2.1.2 Direct Current

2.3 Safety Considerations
The following general safety precautions must be covered during
all phases of operation of this equipment. Failure to comply with
these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and
intended use of the equipment.
Disconnect or do not connect the power supply cable in the
following circumstances:
• If the power supply cable or any other attached cables are
frayed or damaged.
• If the unit is exposed to rain or excessive moisture, or liquids
are spilled on it.
• If the unit has been dropped or the case is damaged.
• If you suspect service or repair is required.
• When you clean the case.
To protect the equipment from damage and avoid hazardous
situations, follow these recommendations:
• Do not make modifications or parts substitutions.
• Return equipment to Newport Corporation for service and
repair.
• Do not block ventilation openings.
• Keep liquids away from unit.
• Do not expose equipment to excessive moisture (>90%
humidity).

3 Features and
Specifications
3.1 Product Overview
Figure 3: Front Panel System Identification.
The CDR-DCB and CDR-STEP models are PWM amplifiers for
DC brush and permanent magnet step motors, respectively. These
models operate from +48VDC power. Amp OK, Enable and
Step/Direction (for CDR-STEP only) signals are optically isolated
from the motor power.
17

18 Features and Specifications
CDR-DCB and CDR-STEP amplifiers are configured using CDR-
Util Windows software program via RS232 serial interface.
Built with surface-mount technology, these amplifiers offer a full
complement of features for DC brush and step motor control.
CDR-DCB can be set to either torque (current) or speed (voltage)
mode and is used typically with digital controllers that calculate
position and velocity from the motor's encoder.
CDR-STEP driver is able to micro-step precisely and reduce power
automatically.
Current-limit provides protection for motors while optimizing
acceleration characteristics.
The /ENABLE input logic level is active low. The input is
internally pulled up to +5V to interface with most types of standard
motion controllers.
MOSFET output stage delivers four-quadrant power for bi-
directional acceleration and deceleration of motors.
All models are protected against output short circuits (output to
output and output to ground). All models detect base plate over-
temperature condition. The amplifier will not latch the fault
condition.
3.2 Software for CDR-DCB / STEP
Newport C-Drive Setup Utility (CDR-Util ) software enables you
to configure the CDR-DCB or CDR-STEP amplifiers to drive user
specified motion devices. CDR-Util software is used to enter and
manage configuration information. The CDR-Util user interface
features a Windows-based layout designed for ease of use. The
software provides simple menus, list boxes, and push button
selections for control of the Newport’s CDR-DCB and CDR-STEP
amplifiers. Please refer to Section 4 for more detailed information.

3.4 Features and Specifications
3.4.1 System Features
• Windows software configurable motor drive settings.
• Operates from DC power with optical isolation between /Enable
and /Amp OK signals and power stages.
• Drives Newport positioners with motors up to 4 Amps.

20 Features and Specifications
• Separate motor and signal Sub-D type connectors for simpler
cabling.
• +5V @ 200mA available for encoder.
• Fail-safe /ENABLE Input
• Fault Protections: Short-circuits (output-to-output, output-to-
ground), over/under-voltage, and over-temperature.
