Bosch Rexroth AC Inverter Products and CtrlX Industrial Controller

Introduction

Bosch Rexroth offers a comprehensive range of variable speed drives (VSDs) and ctrlX automation solutions designed for efficient, scalable industrial control. The EFC series of AC inverter drives provides reliable motor control for applications such as pumps, fans, conveyors and general machinery, with options ranging from simple V/F control through to advanced sensorless vector control and integrated safety features.

The ctrlX automation platform delivers a flexible, open architecture for modern industrial environments, enabling seamless integration of control, I/O and communication systems. Designed to reduce engineering time and improve system performance, ctrlX supports a wide range of automation applications with future-ready connectivity.

Together, Bosch Rexroth VSDs and ctrlX provide a complete solution for industrial automation, motor control and machine building, allowing users to scale from standalone drive applications to fully integrated control systems.

Dual rated above 30kW
Single-phase 230Vac (nominal), 0.37kW to 2.2kW (constant torque)
Three-phase 400Vac (nominal), 0.37kW to 132kW (constant torque / variable torque)
IP20 single unit suitable for panel mounting
V/F and sensorless vector motor control
Dynamic braking included up to 22kW. External brake units are available for higher ratings.
Removable keypad, which can be panel mounted with a mounting kit
Built-in PLC functionality, allowing a fixed timed sequence to be created
Two option slots available
Supplied with dual-channel STO functionality

EFC3610

The EFC3610 is a general-purpose, entry-level AC inverter drive. With V/F control only, it is ideal for centrifugal fan and pump applications, as well as constant torque loads such as conveyors.

Dual rated above 5.5kW. Constant torque (150% overload) and variable torque (110% overload) ratings are given to each unit
At 4kW and below, units are rated for constant torque only (150% overload)
Single-phase 230Vac, 0.37kW to 2.2kW (constant torque)
Three-phase 400Vac (nominal), 0.37kW to 22kW (constant torque)
IP20 single unit suitable for panel mounting
V/F control only
STO not available
Dynamic braking included on all units
Removable keypad, which can be panel mounted with a mounting kit
Two option slots available
No PLC functionality

EFC5610 without STO

The EFC5610 without STO is a well-featured VSD up to 22kW. With sensorless vector control as well as V/F control, it is suitable for a range of industrial applications including conveyors, compressors, mixers and large fans.

Dual rated above 5.5kW. Constant torque (150% overload) and variable torque (110% overload) ratings are given to each unit
At 4kW and below, units are rated for constant torque only (150% overload)
Single-phase 230Vac, 0.37kW to 2.2kW (constant torque)
Three-phase 400Vac (nominal), 0.37kW to 22kW (constant torque)
IP20 single unit suitable for panel mounting
V/F and sensorless vector motor control
STO not available - factory-fitted product variation available; see below.
Dynamic braking included on all units
Removable keypad, which can be panel mounted with a mounting kit
Two option slots available
Built-in PLC functionality, allowing a fixed timed sequence to be created

Cold Plate

The cold plate version of the EFC5610 has all the benefits of the standard EFC5610, but without the heatsink. This allows it to be mounted in control cabinets with a high IP rating or where panel depth is restricted.

EFC5610 cold plate models are rated for constant torque applications (150% overload), but are also suitable for fan and pump loads
Single-phase 230Vac (nominal), 0.37kW to 2.2kW (constant torque)
Three-phase 400Vac (nominal), 0.37kW to 4kW (constant torque)
IP20 single unit suitable for panel mounting
No heatsink - must be mounted on a metal backplate to ensure VSD losses are dissipated effectively
Dynamic braking included on all units
Built-in EMC filters. The earth connection can be removed if required
Removable keypad, which can be panel mounted with an optional kit
Two option slots available for communications and I/O expansion
Supplied with dual-channel STO functionality

ctrlX Industrial Controller

The ctrlX industrial controller can be used in many different ways due to its flexibility and connectivity. The ctrlX platform can be configured and expanded to meet many Industry 4.0 requirements.

ctrlX Products

As well as the main ctrlX control unit, we offer the bus coupler, which allows connection to an EtherCAT bus and enables I/O modules to be added for expansion. Licences are available on a free trial basis and can be purchased once proof of concept has been established.

Please see our YouTube channel for an explanation of the ctrlX products, setup and functionality.
