Danfoss micro drive: Control ac motors up to 30 HP
Compact VLT micro drives now available with more power, M5 frame size.
Renee Robbins
Danfoss Drives has added an M5 frame size to its VLT Micro Drive family. The M5 frame size is 11.5 in. H x 6.5 in. W x 9.8 in. D, and covers the three-phase 380 - 480 VAC, 25 - 30 HP range. The drive offers true side-by-side mounting without any derating due to its compact book-style design.
An Automatic Energy Optimizer function allows the drive to consume less energy, while the Automatic Motor Adaptation feature leverages the motor's full operating potential. According to the company, users will also benefit from up to 150% more torque for up to a full minute, eliminating the need to oversize the drive.

In addition to the new M5 frame size, VLT Micro Drives are also available in single-phase 200 - 240 VAC, 0.25 - 2 HP; three-phase 200 - 240 VAC, 0.25 - 2 HP; three-phase 380 - 480 VAC, 0.5 - 3 HP; and three-phase 380 - 480 VAC, 15 - 20 HP power range configurations. The drive provides IP20 protection even without the terminal cover.
The VLT Micro Drive's smart logic controller integrates the drive and motor for optimum application performance. According to the company, users can program the controller to react on virtually any event, often eliminating the need for a PLC. Additional features include built-in AC and DC brake functions that help the drive transform kinetic energy from the application into braking power, and intelligent heat management and coated electronics for maximized drive reliability and life.
The drive features conformal coated PCBs per IEC 60721-3-3, class 3C3, and provide serial communication via RS 485 Modbus RTU and FC protocols. A detachable Local Control Panel (LCP) with or without a potentiometer, an LCP copy function, as well as a panel-front mounting kit for the LCP all facilitate ease of use. Approximately 100 parameters can be set to optimize energy efficiency and operation. A "flying start" feature provides more uptime, while an electronic thermal relay eliminates the need for external motor protection. A built-in RFI filter saves on cost and space.
