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 mo-
tor are shown in chapter "Connector Pinout" from p.123.
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 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 cor-
rect earthing 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 control leads must be shielded. The shielding must be connected at
both ends (see instructions manual of the servo amplifier).
Cabling:
— Route power cables as separately as possible from control cables
— Connect up the resolver or encoder.
— Connect the motor cables, install motor chokes 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.
Connect up all shielding via a wide surface-area contact (low impedance) and me-
tallized connector housings or EMC-cable glands.
Requirements to cable material:
Capacity
Motor cable less than 150 pF/m
Resolver cable less than 120 pF/m
