be prevented, for example by using the Safe Stop
function or by safe disconnection of the
servomotors.
•
Do not disconnect the cables from the
servomotor while the servo system is connected
to mains voltage. Ensure that the mains supply is
disconnected and the required waiting time has
elapsed before disconnecting or connecting the
hybrid cable or disconnecting cables from the
connection box and/or the power supply module.
•
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
DISCHARGE TIME
The servomotors, the connection box and the power
supply module contain DC link capacitors, that remain
charged for some time after the mains supply is switched
off at the power supply module.
To avoid electrical shock, fully disconnect the power
supply module from the mains before carrying out any
maintenance on the ISD servo system or its components.
Wait for at least the time listed below before carrying out
maintenance work:
Number Minimum waiting time (discharge time)
0-60 servomotors 10 minutes
Note: High voltage may still be present even if the LED on the
ISD connection box is not lit!
Table 3.1 Discharge Time
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 personnel are
trained personnel 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 servo system and its components are used
only as intended.
•
the components are operated only in a perfect
operational condition.
•
the operating instructions are always available
near the servo system in complete and readable
form.
•
the servo system and its components are 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 components, 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.
