ADVANCED MOTION CONTROL MOVES
The simple language does not prevent you from
solving complex problems. The BDS5 has separate
acceleration and deceleration rates, as well as linear,
half S-curve, and full S-curve acceleration profiles.
The BDS5 has Macro Moves for applications where
simple indexes cannot do the job. A Macro Move is a
combination of up to 30 accelerations, traverses, and
decelerations, which are fully precalculated for faster
execution. You can program teach modes where
position end points can be changed by a factory
operator
•
MASTER/SLAVE - ELECTRONIC GEARBOX
The electronic gearbox is used to link two motors
together so that the velocity of the slave is
proportional to the velocity of the master. The ratio
can be from 32767:1 to 1:32767 and can be negative
to allow the slave to move in the opposite direction.
Also, the "index-on-gearing" feature permits phase
adjustments.
•
MASTER/ SLAVE - PROFILE REGULATION
With profile regulation you can control the slave's
motion profile according to an external master motor
or frequency. Profile regulation modifies the velocity
and acceleration of the slave axis without affecting the
final position of the move. You can use profile
regulation to implement "feed rate override."
•
MOTION GATING AND REGISTRATION
The BDS5 can precalculate moves to begin motion
within one millisecond after a transition on the GATE
input. This provides rapid and repeatable motion
initiation. The BDS5 has the ability to capture the
current position within 25 microseconds after a
transition of the HOME input. This results in fast
homing and accurate registration sequences.

The BDS5 has 100 program labels, 50 user-definable
variables, and 50 user-definable switches. It also has
15 mathematical/logical operations and over 150
system variables.
•
USER UNITS
Quantities such as position, velocity, and acceleration
are automatically scaled into user-defined units. This
feature lets you program the BDS5 in convenient units,
such as feet, inches, miles, RPM, and degrees.
•
SUPERIOR SERVO LOOP CONTROL
The BDS5 offers smooth, high-resolution control.
Standard BDS5 position repeatability is better than
one arc-minute, bidirectional. The BDS5 has a 32-bit
position word. The BDS5 position loop completely
eliminates the digital dither normally associated with
positioning systems. Long-term speed stability is
0.01%. The standard system converter (12-bit)
provides a resolution of 0.0005 RPM and a maximum
speed of 8000 RPM.
•
SELF-TUNING
The BDS5 can tune itself. You do not have to be a
servo expert to set up a system quickly. Just specify
the desired bandwidth, and let the BDS5 do the rest.
•
POWERFUL MICROPROCESSOR
The heart of the BDS5 is the 16-bit processor that
delivers high performance. The result: the BDS5 can
control a motor and execute its motion program faster
than a standard positioner can.
•
DIGITAL SERVO LOOPS
Both the position and velocity loops are totally digital.
The digital loops give the BDS5 features not available
in standard velocity drives, such as self-tuning, very
low velocity offset, and digitally-adjustable servo
tuning parameters. The optional analog input permits
you to use the BDS5 as an analog velocity drive.
•
FEED-FORWARD GAIN
The digital feed-forward gain reduces following error
and motion initiation delay, thereby increasing
machine throughput.
•
DIAGNOSTICS
The BDS5 offers a complete set of error diagnostics.
When an error occurs, the BDS5 displays an English
