8.1 Important notes
WARNING
Serious risk of injury through electric shock!
• Only staff qualified and trained in electrical engineering are allowed to wire up the motor.
• Check the assignment of the servo terminal and the motor. Compare the rated voltage and
the rated current of the devices.
• Always make sure that the motors are de-energised during assembly and wiring, i.e. no
voltage may be switched on for any piece of equipment which is to be connected. Ensure
that the control cabinet remains turned off (barrier, warning signs etc.). The individual
voltages will only be turned on again during commissioning.
• Never undo the electrical connections to the motor when it is live. Control and power leads
may be live, even if the motor is not running.
Attention
Smooth operation
• Ensure that there the servo terninal and the motor are earthed properly. See below for
further information regarding EMC shielding and earthing. Earth the mounting plate and
motor housing. Further details of connection types can be found in Section 8.2
• Route the power and control cables as separately as possible from one another (separation
> 20 cm). This will improve the immunity of the system to electromagnetic interference. If a
motor power cable is used which includes integral brake control leads, then these brake
control leads must be shielded. The shielding must be connected at both ends (see below).
• Wiring:
Connect the resolver
Connect the motor cables
Connect shields to shield terminals or EMC connectors at both ends
Connect the motor holding brake
Attention
HF interference
• The ground symbol , which you will find in the wiring diagrams, indicates that you must
provide an electrical connection, with as large a surface area as possible, between the unit
indicated and the mounting plate in the control cabinet. This connection is to suppress HF
interference and must not be confused with the PE (protective earth) symbol (protective
measure according to EN 60204).
Follow the instructions in the circuit diagrams in Sections 8.3 to 8.6
