Connection of the motors with preassembled cables

— Carry out the wiring in accordance with the valid standards and regulations.
— Only use Kollmorgen preassembled shielded cables for the resolver and power con-
nections.
— Incorrectly installed shielding leads to EMC interference and has an adverse effect
on system function.
— The maximum cable length is defined in the instructions manual of the used servo
amplifier.
For a detailed description of preassembled cables, please refer to the regional accesso-
ries manual.

Guide for electrical installation

— Check that the servo amplifier and motor match each other. Compare the rated vol-
tage and rated current of the unit. Carry out the wiring according to the wiring dia-
gram in the instructions manual of the servo amplifier. The connections to the motor
are shown in chapter "Connector Pinout" from p.131.
— 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.
In case of long motor cables (>25m) and dependent on the type of the used servo ampli-
fier a motor choke (3YL or 3YLN) must be switched into the motor cable (see instructions
manual of the servo amplifier and accessory manual).
— Ensure that there is proper earthing of the servo amplifier and the motor. Use correct
earthing and EMC-shielding according to the instructions manual of the servo ampli-
fier which is used. Earth the mounting plate and motor casing.
— If a motor power cable is used which includes integral brake control leads, then the-
se brake control leads must be shielded. The shielding must be connected at both
ends (see instructions manual of the servo amplifier).
— Cabling:

— Connect up all shielding via a wide surface-area contact (low impedance) and me-
tallized connector housings or EMC-cable glands.
