Safety Information
1.1
Warnings, Cautions and Notes
A Warning contains information which is essential for
avoiding a safety hazard.
A Caution contains information which is necessary for
avoiding a risk of damage to the product or other equipment.
A Note contains information which helps to ensure correct
operation of the product.
1.2
Electrical safety - general warning
The voltages used in the drive can cause severe electrical shock and/or
burns, and could be lethal.
Extreme care is necessary at all times when working with or adjacent to
the drive.
Specific warnings are given at the relevant places in this Installation
Guide, and the accompanying User Guide.
The installation must comply with all relevant safety legislation in the
country of use.
1.3
System design
The drive is intended as a component for professional incorporation into
complete equipment or a system. If installed incorrectly, the drive may
present a safety hazard.
The drive uses high voltage and currents, carries a high level of stored
electrical energy, and is used to control equipment which can cause
injury.
Close attention is required to the electrical installation and the system
design to avoid hazards, either in normal operation or in the event of
equipment malfunction. System design, installation, commissioning and
maintenance must be carried out by personnel who have the necessary
training and experience. They must read this safety information and this
Installation Guide carefully.
To ensure mechanical safety, additional safety devices such as electro-
mechanical interlocks may be required. The drive must not be used in a
safety critical application without additional high integrity protection
against hazards arising from a malfunction.
1.4
Environmental limits
Instructions in this User Guide regarding transport, storage, installation
and use of the drive must be complied with, including the specified
environmental limits. The drive must not be subjected to excessive
physical force.
1.5
Compliance with regulations
The installer is responsible for complying with all relevant regulations,
such as national wiring regulations, accident prevention regulations and
electromagnetic compatibility (EMC) regulations. Particular attention
must be given to the cross-sectional areas of conductors, the selection
of fuses or other protection, and protective earth (ground) connections.
This Installation Guide contains instruction for achieving compliance with
specific EMC standards.
Within the European Union, all machinery in which this product is used
must comply with the following directives:
•
97/37/EC: Safety of machinery.
•
89/336/EEC: Electromagnetic Compatibility.
1.6
Safety of personnel
The STOP function of the drive does not remove dangerous voltages
from the output of the drive or from any external option unit.
The STOP and START controls or electrical inputs of the drive must
not be relied upon to ensure safety of personnel. If a safety hazard
could exist from unexpected starting of the drive, an interlock that
electrically isolates the drive from the AC supply must be installed
to prevent the motor being inadvertently started.
Careful consideration must be given to the functions of the drive which
might result in a hazard, either through their intended functions or
through incorrect operation due to a fault (e.g. stop/start, forward/
reverse, maximum speed).
Under certain conditions, the drive can suddenly discontinue control of
the motor. If the load on the motor could cause the motor speed to be
increased (e.g. in hoists and cranes), a separate method of braking and
stopping the motor must be used (e.g. a mechanical brake).
Before connecting the AC supply to the drive, it is important that you
understand the operating controls and their operation. If in doubt, do not
adjust the drive. Damage may occur, or lives be put at sisk. Carefully
follow the instructions in this Installation Guide.
Before making adjustments to the drive, ensure all personnel in the area
are warned. Make notes of all adjustments that are made.
1.7
Risk analysis
In any application where a malfunction of the drive could lead to
damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk. This would
normally be an appropriate form of independent safety back-up system
using simple electro-mechanical components.
1.8
Motor
Ensure the motor is installed in accordance with the manufacturer’s
recommendations.
Servo motors are designed to operate at elevated temperatures which
may reach 100
o
C. Where necessary, precautions to prevent human
contact should be taken.
1.9
Adjustment of parameters
Some parameters have a profound effect on the operation of the drive.
These parameters must not be adjusted without careful consideration of
the impact that would be made on the controlled system. Measures must
be taken to prevent unwanted changes from being made, e.g. due to
error or tampering.
