Only staffs qualified and trained in electrical engineering are allowed to wire up the Motor. Check the assignment of the servo terminal and the motor.Compare the rated voltage and the rated current of the devices.
Always make sure that the motors are de-energised 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.
Never undo the electrical connections to the motor when it is live.
Control and power leads may be live, even if the motor is not running.
Note
Failure free operation
Ensure that the servo terminal and the motor are earthed properly.See below for further information regarding EMC shielding and earthing.Earth the mounting plate and motor housing.
Only use cables approved by Beckhoff for operating the AM8100 with the “one-cable technology” (OCT).
Route the power and control cables as separately as possible from one another (separation > 20 cm).This will improve the immunity of the system to electromagnetic interference.If a motor power cable is used which includes integral brake control leads, then these brake control leads must be shielded.The shielding must be connected at both ends (see sectionShielding concept)
Install all cables carrying a heavy current with an adequate cross-section, as per EN 60204. The recommended cross-section can be found in the technical data.
Wiring
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).
