Motors, Drives & Controls
The Q9 Series of adjustable-speed drives are designed with oversized transistors and heavy-duty dc bus capacitors. The electronic operator interface has an LCD and simple keypad layout. Windows-based software aids programming and monitoring. The drive’s HVAC features include a fire-speed circuit that forces the drive to run at a preset speed during a smoke purge, and a damper-permissive function that can be used to protect from over-pressuring ductwork. Other drive features include PID control, wire-break function and common communications protocols.

Large-capacity ac drive
The SJ700 Series large-capacity ac drive features an improved sensorless vector control algorithm that enables the unit to develop more than 150% starting torque at 0.3 Hz. Using the “0 Hz Domain” open-loop control mode, the drive can develop 130% torque at 0 Hz, which is critical for vertical lift applications. The drive also has a simplified auto-tuning process, built-in sequence programming, voltage surge suppression, advance trip avoidance and configurable sink/source logic on programmable I/O.

Solid-state overload relay
The Motor Insight overload relay features solid-state motor protection with ground fault detection; power, voltage and current monitoring; and flexible communications options. Add-on communication adapters enable users to choose among DeviceNet, Modbus, Profibus and Ethernet/IP protocols, as well as several I/O options. The overload relay system can be used with applications such as coal-bed methane well pumps, low-speed mixers, can pumps, mag drive pumps, fractional horsepower pumps and motors and submersible pumps.

Servo drive with embedded software
The PositionServo is a servo drive with programming and configuration software embedded inside the drive. The software %%MDASSML%% MotionView OnBoard %%MDASSML%% allows the drive to run without having specific servo drive software loaded into a computer. The drive also has communication capabilities such as Ethernet/IP, DeviceNet and Profibus DP protocols. Advanced debugging tools allow users to save variable watch configurations as project files for later recall. Other features include a memory chip, digital and analog I/O and instant drive setup.

Motor management system
The TeSys T motor management system records motor history, statistics and time-stamped faults to give users a real-time view of their motor control. The system consists of a multifunction protection device %%MDASSML%% separate from the automation system %%MDASSML%% and an operator control unit for reading and modification of monitored parameters. The device supports up to five fieldbus types, and offers six motor control functions including overload, two-step and two-speed modes. It guards against motor malfunctions such as overload and current peak.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
