•
In addition to the L1, L2 and L3 supply voltage
inputs on the power supply module, the servo
system has other supply voltage inputs, including
external 24 V DC. Before commencing repair
work, check that all supply voltage inputs have
been switched off and that the necessary
discharge time for the intermediate circuit
capacitors has elapsed.
•
The supply of power to the servo system must be
switched off for repair work. Before disconnecting
or connecting the hybrid cable or disconnecting
cables from the connection box and/or the power
supply module, ensure that the mains supply is
disconnected and the necessary discharge time
has elapsed.
WARNING
HIGH VOLTAGE
The ISD 410 servomotors are electrically powered servo
drives with DC link circuits. The capacitors in the DC links
hold stored energy even after the supply voltage has been
switched off. The total capacitance of the DC link is higher
than that of an individual servomotor because the
servomotors in the system are configured as a group with
their DC links connected in parallel. For this reason, the
capacitor discharge times must always be observed
without fail.
CAUTION
Never connect or disconnect the hybrid cable to or from
the servomotor when voltage is present. Doing so will
damage the electronic circuitry. Observe the discharge
time for the DC link capacitors.
3.4 Qualified Personnel
Installation, commissioning and maintenance of the
ISD 410 servo system may only be carried out by qualified
personnel.
For the purposes of this document and the safety
instructions in this document, qualified staff are trained
staff who are authorised to fit, install, commission, earth
and label equipment, systems and circuits in accordance
with the standards for safety technology and who are
familiar with the safety concepts of automation
engineering.
Additionally, the personnel must be familiar with all the
instructions and safety measures described in these
operating instructions.
They must have suitable safety equipment and be trained
in first aid.
3.5 Due Diligence
The operator and/or fabricator must ensure that:
•
the servomotor is used only as intended
•
the servomotor is operated only in a perfect
operational condition
•
the operating instructions are always available
near the servomotor in complete and readable
form
•
the servomotor is fitted, installed, commissioned
and maintained only by adequately qualified and
authorised personnel
•
these personnel are regularly instructed on all
relevant matters of occupational safety and
environmental protection, as well as the contents
of the operating instructions and in particular the
instructions it contains
•
the product markings and identification markings
applied to the servomotor, as well as safety and
warning instructions, are not removed and are
always kept in a legible condition
•
the national and international regulations
regarding the control of machinery and
equipment, that are applicable at the place of use
of the servo system, are complied with
•
the users always have all current information
relevant to their interests about the servo system
and its use and operation
3.6 Intended Use
The servomotors are intended to be installed in machines
used in commercial and industrial environments.
To ensure that the product is used as intended, the
following conditions must be fulfilled before using the
ISD 410 servomotor:
•
Everyone who uses one of our products in any
manner must read and understand the
corresponding safety regulations and the
description of the intended use
•
Hardware must be left in its original state, which
means that no structural changes may be made
to the hardware
•
Software products may not be reverse-engineered
and their source code may not be altered
•
Damaged or faulty products may not be installed
or put into service
