1.6.2 Guide for electrical installation

Check that the servo amplifier and motor match each other. Compare the rated voltage and
l
rated current of the unit. Carry out the wiring according to the wiring diagram in the instruc-
tions manual of the servo amplifier. The connections to the motor are shown in chapter "Con-
nector Pinout" from (➜ # 200).
Install all cables carrying a heavy current with an adequate cross-section, as per EN 60204.
l
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 amplifier 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
l
and EMC-shielding according to the instructions manual of the servo amplifier which is used.
Earth the mounting plate and motor casing.
If a motor power cable is used which includes integral brake control leads, then these brake
l
control leads must be shielded. The shielding must be connected at both ends (see instruc-
tions manual of the servo amplifier).

Connect up all shielding via a wide surface-area contact (low impedance) and metallized con-
l
nector housings or EMC-cable glands.
Requirements to cable material:

Capacity
Motor cable: less than 150 pF/m
Resolver cable: less than 120 pF/m

1.6.3 Connection of the motors with preassembled cables

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

Route power cables as separately as possible from control cables
Connect the feedback device.
Connect the motor cables, install motor chokes (if applicable) close to the amplifier
Connect shields to shielding terminals or EMC connectors at both ends
Connect the holding brake, if used
Connect shielding at both ends.
