Guide For Electrical Installation; Connection Of The Motors With Preassembled Cables - Kollmorgen AKM2G Serie Manual De Instrucciones

1.6.2 Guide for electrical installation

Check that the servo amplifier and motor match each other. Compare the rated voltage
l
and rated current of the unit. Carry out the wiring according to the wiring diagram in the
instructions manual of the servo amplifier. The connections to the motor are shown in
chapter "Connector Pinout" from (➜ # 245).
Install all cables carrying a heavy current with an adequate cross-section, as per
l
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 amplifier a
motor choke 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 earth-
l
ing 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
l
brake control leads must be shielded. The shielding must be connected at both ends (see
instructions manual of the servo amplifier).
Cabling:
l
Route power cables as separately as possible from control cables
l
Connect the feedback device.
l
Connect the motor cables, install motor chokes (if applicable) close to the amplifier
l
Connect shields to shielding terminals or EMC connectors at both ends
l
Connect the holding brake, if used
l
Connect shielding at both ends.
l
Connect up all shielding via a wide surface-area contact (low impedance) and metallized
l
connector housings or EMC-cable glands.
Requirements to cable material:
l
Capacity
Motor cable: less than 150 pF/m
Feedback 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 feedback and power con-
l
nections.
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 amp-
l
lifier.
For a detailed description of configured cables, please refer to the regional accessories
manual.
