Three-phase synchronous motor English
Danger on physical contact:
Make sure that the electric motor has come to a standstill and is secured against
unintentional restarting before you touch it.
Only touch the output shaft when it is electrically isolated and the motor has come to a
standstill. Otherwise there is a risk due to the rotating rotor.
Danger of burns! Never touch the motor housing when the motor is running at rated
load. The surface temperatures on the motors may exceed 70 °C
5.2 Checks prior to commissioning
• The drive is undamaged and is not located within the danger zone of other equipment.
• The motor is correctly aligned and fastened. All screwed connections are correctly tightened.
• All the appropriate safety devices (mechanical, thermal, and electrical) are mounted.
• The motor connections have been made correctly.
• The cables are not in contact with the surface of the motor.
• The protective conductor system is correct and its functionality has been checked.
• The drive is not blocked (release brake, if present).
• Emergency stop functions have been checked.
• Fan is connected properly and its function has been checked.
5.3 Commissioning, operation
Note on brake function (if present):
The brake is designed as a holding brake with an emergency stop function.
(power failure, emergency stop)
It must not be used as a working brake.
Commissioning must be carried out exclusively by qualified personnel.
Please refer to the commissioning instructions for the converter.
Checks during commissioning:
• Release the brake, if necessary.
• Has the functionality of all motor modules such as the brake, encoder, fan, etc., been checked
and are the conditions of use met?
• Have all electrical connections been made correctly and tightened (observe wiring diagrams,
see Section 8 and respectively the enclosed wiring diagrams)?
• Have all protection measures that eliminate the possibility of contact with live parts, hot
surfaces, and rotating and moving parts and modules been observed and are these measures
fully functional?
• Have all output elements been mounted and adjusted in accordance with the manufacturer's
instructions?
• Are measures in place to ensure that the maximum permitted speed n
max
of the motor cannot
be exceeded? The maximum permitted speed n
max
is the highest permitted operating speed
for short-time duty.
Checks during operation:
• Listen out for unusual noises.
• If scraping, scratching, grinding, or other similar noises occur, stop the drive immediately and
locate the cause.
