Guide to electrical installation

Correct wiring is the basis for reliable functioning of the servo system.
Route power and control cables separately. We recommend a distance of at least
200mm. This improves the interference immunity. If a motor power cable is used that
includes cores for brake control, the brake control cores must be separately shielded.
Ground the shielding at both ends. Ground all shielding with large areas (low impedance),
with metalized connector housings or shield connection clamps wherever possible. Notes
on connection techniques can be found on page 52.
Feedback lines may not be extended, since thereby the shielding would be interrupted
and the signal processing could be disturbed. Lines between amplifiers and external
brake resistor must be shielded. Install all power cables with an adequate cross-section,
as per IEC 60204 (ð p.28) and use the requested cable material (ð p. 53) to reach max.
cable length.
The following notes should help you to carry out the electrical installation.
Cable selection Select cables in accordance with IEC 60204 ð p.28.

Wiring Wire the BTB/RTO contact in series into the emergency off
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
