8.2 Guide to electrical installation
The following notes should assist you to carry out the electrical installation in a sensible sequence,
without overlooking anything important.
Cable selec-
tion Select cables according to EN 60204 (ðp.20)
Grounding
Shielding
EMC-compliant (EMI) shielding and grounding (ðp.47)
Earth (ground) the mounting plate, motor housing and CNC-GND of the controls.
Notes on connection techniques are on page42
Wiring Route power leads and control cables separately
Wire the BTB/RTO contact in series into the safety loop
— Connect the digital control inputs to the servo amplifier
— Connect upAGND (also if fieldbuses are used)
— Connect the analog setpoint, if required
— Connect up the feedback unit (resolver and/or encoder)
— Connect the encoder emulation, if required
— Connect the expansion card (see hints from page98)
— Connect the motor cables, connect shielding to EMI connectors at both ends
— Use motor chokes (3YL) for lead lengths >25m
— Connect the external regen resistor (with fusing) if required
— Connect aux. supply (for max. permissible voltage valuesðp. 19)
— Connect main power supply (for max. permissible voltage valuesðp. 19)
— Connect PC (ðp.69).
Final check — Final check of the implementation of the wiring,
—according to the wiring diagrams which have been used.
