Motor chokes AX2090-MD50

A motor choke must be installed between the AX5000 and the motor from a certain motor cable length onwards. The motor choke reduces the commutation current flowing via the screen back into the AX5000 to a permissible value and can also provide a solution to EMC problems.

Installation of the motor choke AX2090-MD50-0012

WARNING

Risk of injury through electric shock!

De-energize all electrical components (servo drive, control cabinet etc.) before commencing the installation or deinstallation of the motor choke.

CAUTION

Destruction of the motor choke!

    • Always install the motor choke vertically on an earthed metallic mounting plate. If no metallic mounting plate is available, you must earth the motor choke; an earthing bolt is provided on the motor choke for this purpose.
    • Ensure adequate ventilation of the motor choke. The permissible ambient conditions are specified in the “Technical data” section.
    • It is essential to maintain the necessary distances to the AX5000 (see sketches below).

    The motor chokes for the AX5000 (a) with a max. rated channel current of 12 A are bolted to the mounting plate (d) below the device.
    ‘Figure 1’ shows a motor choke (b) for one channel.
    In the case of 2-channel devices, the motor chokes are bolted on top of one another; see ‘figures 2 and 3’. The spacer (e) is supplied with the motor choke.

     

    Motor chokes AX2090-MD50 1:

    Electrical connection

    The motor choke is connected using the ‘plug & play’ method. The two plugs of the existing motor cable are unplugged from the AX5000 and plugged into the sockets on the motor choke. The two plugs of the integrated motor choke cable are then plugged into the socket of the AX5000.

    Motor chokes AX2090-MD50 2:

    Connection cables

    Use exclusively Beckhoff motor cables and firmly tighten the connecting plugs. Max. brake away torque - M4 thread = 1,5 Nm ±0,1 Max. brake away torque - M3 thread (motor plug)  = 0,6 Nm ±0,1
