Expanding CANopen inverter series

At the Hannover Messe 2018, SEW-Eurodrive introduced two new sizes for the Movitrac LTE-B+ frequency inverter series and in doing so is increasing the maximum output power to 37 kW. It provides a CANopen interface.

The frequency inverter can be used for applications such as small conveyor belts, fans, ventilators, barriers, treadmills, portable pumps, wool carding, and dynamic weighing of packages. It is now available in five sizes covering a power range from 0,37 kW to 37 kW for one-phase line voltages of 115 V and 230 V and three-phase line voltages of 230 V and 400 V. A CANopen interface is integrated.

The product features a motor control in V/f and LVFC for energy-optimized power injection with various loads as well as control of new energy-efficient motors based on permanent magnets. An integrated EMC filter for environments sensitive to interference and an integrated PI controller for basic quantity and flow rate control are provided.

The product features an emergency mode for critical applications. The design is made for small control cabinets or direct use in the field with IP-rated housing. Optional external control plate with organic light emitting diode (OLED) technology for plain text display of parameters and function data is another feature.

In addition to the normal version with an IP20 degree of protection for installation in the control cabinet, there is also a variant with an IP66/NEMA4 degree of protection for use in special ambient conditions. This enables these frequency inverters to perform their tasks even in dusty or wet conditions.
