Reduce cabinet height
by directly stacking
rows of drives. Control
Techniques’ patented
Ultrafl ow™ technology
expels heat directly
outside of the cabinet
through the rear of the
drive* and removes heat
build-up in the cabinet.

Ultrafl ow™’s guided
internal airfl ow prevents

ingress on drive circuits and,
combined with conformal
coating, minimizes
contamination risk.

An intelligently controlled
fan optimizes fan lifetime
and minimizes acoustic
noise, while contributing
to the maximum thermal
cooling by Ultrafl ow™.

Ultrafl ow™ requires only
a 32 mm (1.25 in) hole
in the cabinet meaning
rapid, trouble-free
installation**

Ultrafl owTM is a registered Trademark of Control Techniques
* Drive heat dissipation can also be achieved via vents on top of the drive, as standard.
** Frames 2 and 3 require 2 x 32mm (1.5 in) holes

Motion Control

System Architecture

Drive-based Motion

(Decentralised/Distributed
Motion Intelligence)

In a distributed motion control system, the motion
control capability is distributed on-board the
individual drives. This includes the position loop,
motion profi le and sometimes even all or part of
the PLC logic.

◼ Each axis is fully independent, but coordination

can be achieved by synchronizing drives over
the network using Real-Time Motion over
EtherNet (RTMoE).

◼ In small machines, a drive-based system can be

standalone, whereas in larger systems it is more
commonly connected to a PLC (or IPC) over a
fi eldbus which, in this case, does not need to be
strictly deterministic.

M750 EtherNet

M751 Base

MCi210 Option Module

Key advantages

◼ A drive-based system off ers superior

motor control performance, as the
on-board loops typically run faster,
and it avoids the delays of network
communication.

◼ A distributed motion architecture can be

very cost-eff ective, as it forgoes the need
of an expensive central motion controller
and, by using the onboard logic, allows to
take some load off the central PLC.

◼ It is easily scalable, as the load of the

PLC, where present, does not increase
signifi cantly with the number of drives
connected.

◼ PC Tools provide similar ease of

commissioning and maintenance to a
centralised solution.

14

Controller-based Motion

(Centralized Motion
Intelligence)

A central controller generates the motion profi les of all axes
and in some cases even closes the position loop. In this
architecture the servo drives, often referred to as amplifi ers,
simply follow the setpoint they receive from the controller.

◼ The servo drives are normally connected over an EtherNet

network, using a fast and deterministic protocol such as
EtherCAT.

◼ In modern systems, the central controller, PLC-based or

IPC-based, tends to also implement all the machine logic.

Key advantages

◼ Ease of coordinating the motion of multiple axes in a single

program.

◼ Single storage location for the whole machine program,

and potentially even drive parameters, simplifying
maintenance.
