Important notes

DANGER
Serious risk of injury through electric shock!
  • Only staff qualified and trained in electrical engineering are allowed to wire up the motor.
  • Check the assignment of the stepper motor output stage and the motor. Compare the rated voltage and the rated current of the devices.
  • Always make sure that the motors are de-energized during assembly and wiring, i.e. no voltage may be switched on for any piece of equipment which is to be connected. Ensure that the control cabinet remains turned off (barrier, warning signs etc.). The individual voltages will only be turned on again during commissioning.
  • Control and power leads may be live, even if the motor is not running.
Note
Smooth operation
  • Ensure that the motor is grounded properly. See below for further information regarding EMC shielding and earthing. Earth the mounting plate and motor housing.
  • Use only cables approved by Beckhoff for use with the
    AS1000 stepper motors.
  • Wiring:
  • Connecting the feedback cable (optional)
  • Connect the motor cables
  • Shielding at both ends (shield terminal or EMC plug)
Note
HF interference
  • The ground symbol , which you will find in the wiring diagrams, indicates that you must provide an electrical connection, with as large a surface area as possible, between the unit indicated and the mounting plate in the control cabinet. This connection is to suppress HF interference and must not be confused with the PE (protective earth) symbol (protective measure according to EN 60204).
