Machine Health
Vibration and shock sensors are being integrated into the encoder or the motor
to provide asset health insights. The ADXL1002 ultralow noise
(
25 μg/
√
Hz in ±50 g
range
)
, high frequency, ±50 g MEMS accelerometer provides high data bandwidth
vibration sensing up to 11 kHz
(
3 dB point
)
with a resonant frequency of 21 kHz.
ADXL1002 provides a lower cost and lower power alternative to piezoelectric
sensors. ADXL1002 enables monitoring of slow rotating equipment down to DC
while also reducing calibration requirements when compared to piezo sensors.
ADXL354 is a low noise, low power, 3-axis MEMS accelerometer in a small
(
3 mm
× 5 mm
)
package with a digital interface, SPI
(
3- and 4-wire
)
, and I

C to provide
a compact solution for vibration sensing integration in encoders.
The ADI OtoSense
™
Smart Motor Sensor is an AI-based, full turnkey hardware
and software solution for condition monitoring of electric motors, combining
best-in-class sensing technologies with leading-edge data analysis. Agnostic of
motor type, ADI OtoSense SMS covers the most critical diagnostics, translating
data into actionable insight that enables you to forecast maintenance cycles and
avoid unplanned downtime.
Network Interface
Smart manufacturing is based on a network of intelligent motion applications
sharing data between the assets and the higher-level control and management
network. ADI's robust, low power, and low latency PHYs include the ADIN1200
(
10/100
)
PHY and the ADIN1300
(
10/100/1000
)
PHY. Both these Industrial Ethernet
PHYs were developed for industrial applications that require operating ambient
temperature up to 105°C and have been extensively tested to EMC and robustness
standards to operate in harsh industrial applications. Low latency PHYs enable
a lower cycle time network that can support more devices connected to the
network and meet the timing requirements for complex, high performance deter-
ministic motion applications. For deterministic Industrial Ethernet connectivity,
ADI's layer 2 Industrial Ethernet embedded 2-port switches. fido5100 and fido5200
support PROFINET, Ethernet/IP, EtherCAT, Modbus TCP, and Ethernet POWERLINK
Industrial Ethernet protocols with any processor, any protocol, any stack.
Motion Controller
The motion controller provides the processing engine to generates the PWM
signals to drive the power semiconductors and receives the current and position
feedback signals to control the motors speed and torque. Robust, high ambient,
high power density power management solutions are required to power the
controller, which is often an FPGA or a processor with optional power supply
sequencing and power telemetry capabilities. Analog Devices' Power by Linear
™
power management ICs and power modules provide the foundation for powering
today's and tomorrow's intelligent motion applications. The motion controller is
often located in a central rack that needs to communicate over a large distance
to the encoder. This is where ADI's isolated and nonisolated RS-485 transceivers
are used for serial communication of the encoder position feedback information
to the motion controller. The ADM3066E, a ±12 kV IEC ESD protected, full-duplex
50 Mbps RS-485 transceiver, provides a high bandwidth, high ambient
(
125°C
)
,
robust communications solution in a small 3 mm × 3 mm package size for
encoder applications.
