Description

  • The LMC Pro2 Motion Controller is installed in a cabinet.

  • The LMC Pro2 Motion Controller is connected to the Lexium™ MC12 multi carrier track with pre-assembled cables. If you do not use pre-assembled cables, make sure not to exceed a Sercos cable length of 50 m (164 ft).

  • The LMC Pro2 Motion Controller communicates with the Lexium™ MC12 multi carrier track via Sercos bus.

  • The Sercos bus

    is distributed from segment to segment via the Lexium™ MC communication interconnects.

Connecting the Sercos Bus to the Lexium™ MC12 multi carrier Track

The following describes the Sercos bus connection from the LMC Pro2 Motion Controller to the Lexium™ MC12 multi carrier track:

Step

Action

1

Connect the Sercos cables (5) to the LMC Pro2 Motion Controller (2).

2

Connect the Sercos cables (5) to the Lexium™ MC communication interconnect with the two Sercos connectors (7) at the top of a segment. Verify that the Lexium™ MC communication interconnect is fixed with its four corresponding screws (M3x8) to the segment, with a torque of 0.6 Nm (5.31 lbf-in).
The Sercos port P1 (CN12) of the controller must be connected to the Sercos port P1 of the Lexium™ MC12 multi carrier track.

NOTE: If you have to remove a connector from the cable, for example, to lead the cable through a cable bushing, make sure to reconnect the wires of the cable correctly to the connector afterwards. Observe the requirements for the degree of protection and the EMC regulations.
 WARNING
UNINTENDED EQUIPMENT OPERATION
Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Additional Wiring Example

Open track

With an open track, you need a communication interconnect (7) at the beginning of the open track with one Sercos (and one SFO) connector and a communication interconnect (9) at the end of the open track with one Sercos connector.
