For EtherCAT, stand-alone I/O systems with protection class IP 20 are available as EtherCAT Terminals.

Unlike the Bus Terminals, in which the fieldbus signals are realized in a Bus Coupler

on a terminal bus that is internally independent of the fieldbus,

the EtherCAT protocol remains fully intact within the individual terminal.

The EtherCAT coupler supports the operation of all Bus Terminals.

As far as the user is concerned, the analog inputs/outputs are handled no differently than in the other

series.

The information is processed as a byte array in the process image of the controller.

Analog and multifunction Bus Terminals can be adapted to each specific application.

Depending on the type, the registers of the analog Bus Terminals contain temperature ranges,

gain values and linearization characteristics.

The Bus Terminals store settings permanently in a fail-safe manner.

In addition, the Bus Terminals can be optionally controlled via the control system.

With function blocks (FB), the programmable logic controller (PLC) handles the

configuration of the entire periphery during the startup phase.

If required, the controller can upload the configuration data created centrally in order to manage and

store them centrally.

As a result, no new adjustments are required when changing bus terminals.

The controller automatically sets the required settings at power-up.

Mounting

Multiple mounting standards are available to meet common International

standards.

Smoothness

Smooth performance results from low-cog, low-harmonic distortion

magnetic designs.

Connectivity

Rotatable IP65 connectors, or straight connectors are both available

to provide flexibility. Single connectors/plugs (combined power and

feedback) are also available to minimize motor and cable cost (SFD and

Absolute Digital Encoders only).

Thermal

Windings are rated conservatively at 100°C rise over a 40°C ambient

while using 155°C (class F) insulation materials. Motors meet applicable

UL, ULC, and CE requirements and include thermistors.

Additional Options:

• Holding brakes

• Shaft sealing options available

• Feedback devices

• Shaft and mounting variations

• Custom windings

• Thermal sensor options

Features

Torque

0.64 to 72 Nm maximum continuous torque (5.6 to 640 lb-in) in 23 frame/

stack combinations. Specific torques are often available from multiple

frame sizes to optimize mounting and inertia matching capabilities.

Speed

Speeds up to 8000 rpm meet high speed application requirements.

Windings tailored to lower speeds are also available.

Voltage

AKM2G motors can be applied to all standard global voltages. Windings

are specifically tailored to work with drives powered by 120. 240. 400 or

480 Vac. AKM2G motors can be operated on DC voltages and voltages

of less than 120Vac; for these applications please contact Kollmorgen

Feedback

AKM2G motors include resolver, Absolute Digital Encoders, or SFD

(Smart Feedback Device) feedback options to meet specific application

requirements.

AKM®2G represents the latest evolution of the industry leading AKM motor product family.

With average continuous torque increases of 30%, OEMs and users can achieve substantial machine

performance increases without increasing the size of the motor.

The improved torque density allows a smaller motor to be used which reduces the machine footprint

without sacrificing performance.

• Extensive selection of feedback options to match application and performance requirements

• Ready for Industry 4.0 using data transfer / storage in motor feedback

• High efficiency electromagnetic design and materials to achieve IE-4 efficiency

• Shaft, mounting and connector options for optimal flexibility

• Energy saving holding brake option

• CE, UL, RoHS, REACH and EAC conformance

AKM®2G Servo Motor Series

AKM2G Motors Offer Extremely High Torque Density and High Acceleration The AKM2G high-

performance motor series offers a wide range of

mounting, connectivity, feedback and other options. These motors offer superb flexibility to meet

application needs with:

AKM®2G SERVO MOTOR SER I ES

• 6 frame sizes (58 to 192 mm)

• 23 frame-stack length combinations

• More than 70 standard windings

Greater Flexibility

More options to match needs

• AKM2G is designed to support a wider array of feedback, brake, thermal sensor and shaft

seal options – this greater flexibility means a higher probability of meeting application

requirements with a standard product.

• The AKM2G design has the potential for greater CoEngineering (modification) thanks to the

new housing design.  With a more flexible design for CoEngineering addressing applications

not covered by catalog standards is increased.

Higher Efficiency

Reduce energy consumption

• AKM2G has lower equivalent resistance than competitive solutions. For equivalent motor

frame sizes AKM2G will typically be more energy efficient (2-5%).

• Energy consumption is reduced with AKM2G compared to competitors.

Reduce machine space

• For equivalent torque it is possible to use a smaller size motor than competitive motors.

• The range of AKM2G sizes provides for optimizing for length or flange square depending on

which dimension is most critical.

• Use of the smaller motor saves space achieving equivalent performance in a smaller

footprint machine or saving space for other machine elements.

which dimension is most critical.

• Use of the smaller motor saves space achieving equivalent performance in a smaller

Increased Torque

Higher performance

• For a given frame size the AKM2G provides an average continuous torque increase of 30%

compared to competitive motors of equivalent size.

• Higher torque in the same package size increases machine performance (greater throughput,

move heavier loads, etc.).

Wider Speed Range

Faster operation

• For many AKM2G sizes the maximum speeds are higher than competitive motors.

• Higher speeds  operate machines faster  greater throughput.
