Issue Number: 4
1 Introduction
1.1 Important information about this User
Guide and the Installation Guide
Variable speed drives may be hazardous if misused.
Carefully follow the instructions in this User Guide, and
especially those in Chapter 1 Safety Information in the
Installation Guide.
Read this User Guide before starting the installation or the
setting up process.
This User Guide is arranged on a step-by-step basis to lead you through
the following:
• When to refer to the Installation Guide
• Making signal and data connections
• Learning how to operate the Drive
• Setting up the Drive for the majority of applications
When a motion controller is used for controlling the M’Ax (Drive), this
User Guide does not contain all the information required for setting up
the Drive. In this case, refer to this User Guide in conjunction with the
instruction manual(s) for the motion controller. This is necessary not only
for setting up the Drive and servo system, but also for ensuring the user
is made aware of all the related safety issues.
For advanced programming of the Drive, refer to the M’Ax Advanced
User Guide which can be obtained from the Drive Centres and
Distributors listed at the end of this User Guide.
1.2 Models and versions of the Drive
The M’Ax is a range of high-performance single-axis servo amplifiers for
controlling permanent-magnet brushless motors that are fitted with a
Control Techniques Speed Loop Module (SLM).
Each model in the M’Ax range can be supplied in either of two versions,
each possessing a variation in functionality specific to a particular type of
application. The version code is a suffix to the model number. See
Table 1.1 and Table 1.2 .
Table 1.1 Model sizes, model numbers and current ratings
*For M’Ax 412:
A line reactor is required when the load duty cycle is ≥70% duty
cycle and the overall cycle rms current is ≥12A.

1.3 Familiarising yourself with the Drive
before installing it
If this is your first encounter with the M’Ax, you may wish to try it out in a
convenient environment before installing it. From this, you can learn
how to set up and control it. Appropriate guidance is given later in this
User Guide.

1.4 Methods of control
Each version can be operated as a standalone unit where all the control
functions take place in the Drive (host mode); each version is supplied
configured for this form of control. Alternatively, a Drive (in particular,
version _SL) can be configured by the user to be controlled by an
external host (motion controller) communicating by

technology
whichisanEIA485two-wirehigh-speeddatacommunicationsnetwork
specially designed by Control Techniques for linking the elements of
servo systems. By this means digital control and synchronisation are
maintained between all the elements. Data, which consists of unit
addresses, parameter numbers and values, is transferred at 125µs
intervals and at a rate of 2.5Mbits/second.
