Notes on wiring

Performance data
}
Check the allocation of servo amplifier and motor. Compare the units' mains voltage
and rated current.
}
Make sure that the maximum permitted rated voltage at connections L1, L2, L3 or +DC,
-DC is not exceeded by more than 10 % (see EN 60204-1, paragraph 4.3.1). Otherwise
the servo amplifier (e.g. brake chopper) could be damaged.
Fuse protection
}
Provide adequate fuse protection for the mains voltage and 24 V supply. Please also
refer to the guidelines provided under "Residual current devices".
Cable layout
}
Power and control cables should be laid separately. We recommend a distance greater
than 20 cm. This will improve EMC noise immunity.
}
If you are using motor power cables with integrated brake control wires, the brake con-
trol wires must be shielded separately. Connect the shield at both ends.
Shielding
} Shields should be connected over a wide area (low impedance). Use metallised con-
nector housing or shielded terminals. Information on the connection technology can be
found under "Connection cables".
}
On shielded cables, the shielding must be continuous. Any interruptions must be
bridged over a wide area.
}
Cables between the servo amplifier and the external brake resistor should have their
own shield.
Connection cables
}
All power cables should have an adequate cross section in accordance with EN 60204
(see section entitled "Connection cables"). To achieve the maximum cable length, use
cable material of the quality described under "Connection cables".
E-STOP circuit
} The relay output for operational readiness (BTB) must be incorporated into the plant's
emergency stop circuit. BTB contact: No safe signal
