► EMC filter can be disconnected by EMC screw.

► Built-in DC reactor of EFC 5610 30 kW and above.

 

Safety Torque off(STO)

► Class 0 cutoff refers to EN60204-1 standard, and got SIL3 certificate.

Up to 45 °C ambient temperature without derating

 

Additional communication options

► In addition to PROFIBUS DP and CANopen also a SERCOS III, PROFINET IO, Ethernet IP, Modbus TCP, EtherCAT are available. Especially, the Rexroth exclusive SERCOS III communication function Communication rate could be microsecond level.

Application Fields

 

HVAC – Fans, pumps, air conditioning

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Energy savings calculator

► Keeps track of the achieved energy savings.

Life time reminder

► Reduces downtime by helping to organize the maintenance

schedule.

Speed tracing

► For smooth catching and restarting of a running fan.

Dry pump protection

► Automatically detects a dry running pump to protect the

equipment.

Pump cascading

► Use Application Specific Firmware and relay card,

4 maximum pumps could be circularly controlled by

frequency converter.

 

Textile and Dyeing – Heat setting stenter, twister, air-flow spinning

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Smart cooling concept

► Double duct design isolates heat sink and semiconductor to prevent semiconductor from pollution.

► No cooling fan up to 1.5 kW and detachable cooling fan above 1.5 kW for cotton fiber easy clean.

Import PCBA coating

► Coating materials is made in Germany, enhanced anticorrosion in high temperature and humidity.

Low voltage ride-through

► Derating output when voltage reduced on power grid.

DC generatrix

► DC generatrix operation to reduce the technical influence from instable power supply, and save energy through load sharing.

Metal processing machinery – Lathe, grinder, drill, planer, borin

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Compact design

► DIN rail and side by side mounting to save space.

High start torque

► To meet the process demand of high strength metal cutting, avoid overcurrent and overload during low speed operation .

Quick and dynamic response

► Accurate speed control for highly smoothness and quality especially for concavo-convex workpiece surface.

Over excitation braking

► Can help to reduce braking times up to 50 %, without an external break resistor.

Safety Torque off(STO)

► Frequency converter false tripping prevent for operation and maintenance safety.

 

Food and packaging – Conveyor, blow molding, blender, cutter, labeling

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Quick connectors and DIN rail mounting (up to 7.5 kW)

► Quick and easy installation and maintenance.

Rubber and plastic machinery – Scroll extruder, pelletizer, bagging

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Compact design

► DIN rail mounting (up to 7.5 kW) and side by side mounting (up to 22 kW), to save cabinet space.

High start torque, 200 % at 0.5 Hz

► To ensure the extruder can start up and operate during the uneven heating temperature environment.

High control accuracy, fast dynamic response

► Precise control is to ensure the material thickness evenly, in order to save cost and ensure the quality of products.

Torque limit and slip compensation

► Especially used for constant output torque. Minimize the torque fluctuation and improve the extrusion process quality.
