Three-phase synchronous motor English
Installing and uninstalling safety devices:
The electric motor may not be commissioned without first mounting the safety
devices.
The motor must be put out of operation when installing and dismantling components
and systems which are provided for monitoring the motor for safe operation.
Danger on physical contact:
Make sure that the electric motor has come to a standstill and is secured against
accidental 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 protective conductor system is correct and its functionality has been checked.
• The cables are not in contact with the surface of the motor.
• 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
Notes on the brake function (if present):
The brake is designed as a holding brake with an emergency stop function.
(power failure and 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 and the cooling system.
Checks during commissioning:
• Release the brake, if necessary.
• Have all the modules of the motor such as the brake, encoder, fan etc. been checked and are they in
compliance with the conditions of use?
• Were all electrical connections executed correctly and tightened properly? (observe wiring diagrams,
see Section 8 and respectively the enclosed wiring diagrams).
• Have all protection measures which eliminate the possibility of physical contact with live parts, hot
surfaces, rotating and moving parts been followed and are these measures fully functional?
• Have all output elements been mounted and adjusted in accordance with the manufacturer's
instructions?
