Dynapar Introduces High Speed Absolute Encoder for Servo Duty

GURNEE, Ill.--(Business Wire)--Dynapar announces the introduction of the compact Acuro(TM )AD34
and AD35 Series absolute encoder. The new encoder utilizes the
company's proven OptoASIC engine for reliable absolute positioning and
speed feedback up to 10,000 RPM. This high-speed capability coupled
with an operating temperature range of up to 120 degrees C makes it
perfectly suited for use in servomotor applications. In addition to
its compact 37mm diameter and short mounting depth, the AD34/35
absolute encoder is available with an unbreakable Mylar code disc (100
degrees C maximum temperature) capable of up to 17 bits of singleturn
resolution.

Fully Digital Control Loop

The new OptoASIC technology is 100 percent digital and enables the
user to transition to a truly digital drive system. Conventional users
will benefit from the available analog sine wave signals for feedback
of speed and position data. In addition, the new absolute encoder will
provide fully digital position data up to 17 bits over the BiSS
interface with a variable clock rate up to 10 MHz. Backward
compatibility to most existing drives is not a problem when the unit
is ordered with SSI + analog output with 2048 sine/cosine periods per
revolution.

Integrated Diagnostic System

The AD34/35 has an integrated diagnostic system that controls and
regulates the data signals within the encoder. Maximum motor uptime is
achieved through monitoring of system errors or component aging well
before they affect the functionality of the encoder. A code
plausibility check guarantees that the output data always represents
true position, and operating temperature can be measured and read with
eight bit resolution. If programmable limits are exceeded, then the
data are transmitted over warning and alarm bits.

Special Mounting Shaft Saves Time and Money

The AD34 absolute encoder has an industry-exclusive notched 6mm
shaft. What makes this notched shaft unique is its one-step mounting
process. The user simply presses the encoder on the motor shaft in one
smooth motion and then secures the supplied flexible tether or torque
arm. The small notch in the shaft creates a friction fit within the
motor shaft, providing a solid mount with high torque transfer without
the use of adhesives, mounting screws, or keyways. The encoder is just
as easily removed by reversing the steps. The AD35 has a traditional
hub shaft arrangement that eliminates the need for flexible couplings.

Price and Availability

The AD34/35 encoder is built to order and immediately available
for the general market. Dynapar will market the encoder under its
Hengstler brand name, and list pricing starts around $275. For custom
OEM applications and volume pricing, contact a Dynapar representative
