II.3 Commissioning
The procedure for commissioning is described as an example. A different method may be
appropriate or necessary, depending on the application of the equipment.
Only specialist personnel with extensive knowledge in the areas of electrical engineering /
drive technology are allowed to commission the drive unit of servoamplifier and motor.
Caution!
Check that all live connection points are safe against accidental contact. Deadly
voltages can occur, up to 900V.
Never undo the electrical connections to the motor when it is live. The residual
charge in the capacitors of the servoamplifier can produce dangerous voltages up
to 300 seconds after the mains supply has been switched off.
The surface temperature of the motor can reach 100°C in operation.
Check (measure) the temperature of the motor. Wait until the motor has cooled
down below 40°C before touching it.
Make sure that, even if the drive starts to move unintentionally, no danger can
result for personnel or machinery.
l Check the assembly and orientation of the motor.
l Check the drive components (clutch, gear unit, belt pulley) for the correct seating
and setting (observe the permissible radial and axial forces).
l Check the wiring and connections to the motor and the servoamplifier.
Check that the earthing is correct.
l Test the function of the holding brake, if used.
(apply 24V, the brake must be released).
l Check whether the rotor of the motor revolves freely
(release the brake, if necessary). Listen out for grinding noises.
l Check that all the required measures against accidental contact with live and
moving parts have been carried out.
l Carry out any further tests which are specifically required for your system.
l Now commission the drive according to the commissioning instructions for the
servo amplifier.
l In multi-axis systems, individually commission each drive unit
(servoamplifier and motor).
