Connecting the Drive

Follow the instructions in this chapter for product familiarisation as
well as permanent installation.
Personnel requirements
The Drive must be installed and operated only by
personnel having the necessary training or experience.
WARNING
Motor safety
If this is the first time the Drive has been operated,
ensure that no damage or safety hazard could arise
from the motor starting unexpectedly.
WARNING
For product familiarisation as well as full installation,
the motor must be fixed down and the shaft guarded
against inadvertent contact.
Stored charge
The Drive contains capacitors that remain charged to a
potentially lethal voltage after the ac supply has been
disconnected. If the Drive has been energized, the AC
WARNING
supply must be isolated at least five minutes before
work may continue.
Wait 30 seconds after removing power to the Drive
before inserting or removing control cables as 'hot
plugging' cables can result in damage to the Drive or
SLM.
CAUTION

Making electrical connections

Setting up the Drive without an AC supply...
If required, the Drive can be set up for the application without the use of
an ac supply. In this case, an Auxiliary back-up supply must be
connected. Before continuing, see Types of back-up supplies on page
17 and Appendix E Auxiliary Back-up Supply on page 99.
Sending a motor-overload alarm to the system or
motion controller
A motor-protection alarm is indicated by software parameter 10.17
changing to logic state 1. This can be detected by the controller in either
of the following ways:
• Reading parameter 10.17 via serial communications; in this case,
make the appropriate signal connections shown in Example signal
connections on page 7 and see Appendix C Serial Communications
on page 87.
• Assigning a digital output to parameter 10.17 and making a dedi-
cated signal connection from the Drive to the controller; in this case,
before continuing, see Appendix F Motor Thermal-Overload Protec-
tion on page 104.
