Connecting the supply voltage
Never remove or attach the connections while voltage is applied.
WARNING!
Electric shock
Contact with live parts will result in serious injury.
Switch off the supply voltages to all connected devices!
Hazardous values may still be present up to 5 minutes after the voltage is switched off,
due to residual charges in the servo amplifier’s capacitors. When the shaft is rotating
(externally driven, running down) the motor acts as a generator. This means that
hazardous voltages will be present at the connection terminals.
The direction of rotation of the servo motor is determined by the phase sequence of the
supply voltage. The servo motor is designed so that the motor shaft rotates to the right
when it is connected as shown in Fig. 7-15.
Any change to the direction of rotation must be made via the servo amplifier. Servo
amplifiers can change the direction of rotation of the servo motor by changing the phase
sequence electronically.
