The following notes should help you to carry out the electrical installation in a sensible
sequence, without overlooking anything important.
Cable selection
Select cables in accordance with EN 60204 ð p.22.
Grounding
Shielding
For EMC-compliant shielding and grounding ð p.38.
Ground the mounting plate, motor housing and CNC-GND of the
control system. Notes on connection techniques ð p.34.
Wiring
Route power leads and control cables separately.
Wire the BTB/RTO contact in series into the safety circuit of the
system.
— Connect the digital control inputs and outputs.
— Connect up AGND (also if fieldbuses are used).
— Connect the analog input source, if required.
— Connect the feedback device.
— Connect the encoder emulation, if required.
— Connect the expansion card
— (see corresponding notes from page 85 on).
— Connect the motor cable
— Connect shielding to EMC connectors (shield connection) at both
— ends. Use the motor choke (3YLN) if cable > 25 meters.
— Connect motor-holding brake, connect shielding to EMC
— connector/shield connection at both ends.
— If required, connect the external regen resistor (with fusing).
— Connect the auxiliary supply
— (maximum permissible voltage values ð p.22).
— Connect the main electrical supply
— (maximum permissible voltage values ð p.22).
— Connect the PC (ð p.58).
Final check
— Final check of the implementation of the wiring against the
— wiring diagrams that have been used.
