Networking AC Drives with built-in Modbus Communications

GS-RS485-4gRS485 comm board, 8 port, GS-RS485-8 gRS485 comm board, 8 port,

RS485 Communication Boards

The RS485 Communication Boards provide an easy means to break out the RS485 signal to several drives at one location. This is a star configuration, but the transmission errors are negligible, so this configuration is acceptable for proper operation of the VFDs.

Add Ethernet Connectivity for Advanced Functionality
Add Ethernet connectivity and open up the path to the most advanced functionality today.
When using our Hx-ECOM100 Modbus TCP/IP Ethernet Modules in our DL05/06, DL205 and DL405 family of PLC's or our Kepware OPC Servers allowing Ethernet connectivity to the Danfoss FC51 Micro Drive . The NET485 Modbus is a simple device with software all packaged inside a simple cable. The NET485 Modbus will take your serial modbus data stream and convert it to Modbus TCP Ethernet packets with no changes to your software.

Software: The NET485 Modbus is preloaded with Modbus firmware and maps all current serial Modbus commands and registers to Ethernet Modbus TCP commands and registers.

Product Range

1 x 200–240 V AC 0.18–2.2 kW

3 x 200–240 V AC 0.25–3.7 kW

3 x 380–480 V AC 0.37–7.5 kW

VLT® Micro Drive is a genuine VLT® frequency converter with unsurpassed reliability, user-friendliness, condensed functionality, and extremely easy to commission.

Terminal numbers are named in the same manner as in the rest of the VLT® family.

Despite the compact size and the easy commissioning, VLT® Micro Drive can be set up to perform perfectly even in complex application set-ups. Approximately 100 parameters can be set to optimize energy efficiency and operation.

 

Coated PCB standard

For harsh environments.

Real space saving side-by-side

A compact book style design allows real side by side mounting without derating.

Minimum penetration of dust

VLT® Micro Drive is designed to keep the forced ventilation away from the electronics. Printed circuit boards are well protected inside the drive.

Built-in RFI

Radio disturbance from motor cables is limited with the built-in RFI filter allowing for 15 m motor cables (screened). Meets EU norms.

Built-in brake functions

With built in DC and AC brake functions, VLT® Micro Drive can transform kinetic energy in the application into braking power to slow down the motor. A brake chopper is built-in the drives from 1.5 kW upwards.
