1 - NOTICES, MANUAL STRUCTURE AND TERMINOLOGY
1.1 - This manual covers the following items:
•
X-PLUS ET series stepping motor drives in all their standard versions.
•
Standard characteristics of special versions of X-PLUS ET series stepping motor drives (see
chapter 1.2).
•
For models and versions identification see also chapter 3.

•
Drive: electronic part of an electromechanical motion system, which receives some digital or
analog input signals from an external control system and gives to the stepping motor the
suitable phase excitation sequences, in order to obtain the mechanical movements required by
the control system. The drive can also communicate its status to the control system through
some logic signals. In this manual we consider the drive as a BDM (EN 61800-3, chap.3, Fig.1)
•
Control system: part of the machine which decides and controls all machine functions and gives
to the drive all execution commands. It could be a numerical or programmable control, a
personal computer or a specific control card. In the simplest machines it could also be a group
of sensors and electromechanical switches.
•
Electrical supply: all machine parts suitable to supply the drive in a correct way; anti-interference
filter, switches, protection systems and in some cases transformer.
•
Standard drives are all models (see chapter 3 for identification) whose characteristics comply
completely with those described in this manual. Special versions are all models in which some
characteristics differ from the description given in this manual. For these models, some part of
the manual does not apply and, in these cases, you must have the specific "variation sheet"
which becomes an integral part of the manual itself.
1.3 -
Products described in this manual (see identification code in chapter 3) complies with Low Voltage
(2014/35/CE) and Electromagnetic Compatibility (2014/30/CE).
Product standards:
1) UL 61800-5-1 1st Edition – Power Conversion Equipment
2) CSA C22.2 No.274 - Industrial control equipment.
1.4 -
Remember that, as stated in all regulations, compliance exists only when a product is installed and
used in accordance with its destination and following manufacturer prescriptions. Thereby, all
relevant indications about use, cautions, installation and limitations here described must be followed
by user in order to stay within safety and compliance limits: from this point of view, chapter 2, 8 and
10 are particularly important, but the entire content of this manual has to be carefully read and
considered in order to obtain the information necessary for a correct use.
1.5 -
Conformity declaration regarding above mentioned products is kept by R.T.A. (as manufacturer
residing in EEC country) together with technical construction file at authority disposal.
