Important notes
Only specialist personnel with extensive knowledge in the areas of electrical engineering /
drive technology are allowed to commission the drive unit of servo amplifier and motor.
Deadly voltages can occur, up to 900V. Risk of electric shock! Check that
all live connection points (terminal boxes) are safe against accidental
contact. Never undo the electrical connections to the motor when it is live.
The residual charge in the capacitors of the servo amplifier can produce
dangerous voltages up to 10 minutes after the mains supply has been
switched off. Measure the DC-link voltage and wait until it has fallen
below 50V. Even when the motor is not rotating, control and power leads
may be live.
The surface temperature of the motor can exceed 100°C in operation.
Risk of burns! Check (measure) the temperature of the motor. Wait until
the motor has cooled down below 40°C before touching it.
The drive performing unplanned movements during commissioning cannot
be ruled out. Make sure that, even if the drive starts to move
unintentionally, no danger can result for personnel or machinery.
The measures you must take in this regard for your task are based on the
risk assessment of the application.

Guide for setup
The procedure for setup is described as an example. A different method may be appro-
priate or necessary, depending on the application of the equipment.
l
Check the assembly and orientation of the motor.
l
Check the wiring and connections to the motor and the servo amplifier. Check that
the earthing is correct.
l
Check whether the rotor of the motor revolves freely. 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 setup instructions for the servo amplifier.
l
In multi-axis systems, individually commission each drive unit (servo amplifier and
motor).
