1.7 Setup

1.7.1 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.
DANGER
Deadly voltages can occur, up to 900 V. Risk of electric shock! Check that all live
connection points are safe against accidental contact.
Never undo the electrical connections to the motor when it is live. Risk of electric
shock! The residual charge in the capacitors of the drive can produce dangerous
voltages up to 10 minutes after the mains supply has been switched off.
Even when the motor is not rotating, control and power leads may be live. Measure
the DC-link voltage and wait until it has fallen below 60 V.
CAUTION
The surface temperature of the motor can exceed 100°C in operation. Danger of
light burns! Check (measure) the temperature of the motor. Wait until the motor
has cooled down below 40°C before touching it.
CAUTION
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.
