Control connections

Drive control connections

The control connections are made on the terminal blocks provided in the swing-out
frame of the drive. Refer to the circuit diagrams delivered with the drive, and to
chapter

Supply unit control connections

The supply unit is controlled using the local control devices optionally mounted on
the cabinet door, i.e. the start switch, reset button and emergency stop button. No
additional control connections are used or needed. However, it is also possible to
• halt the supply unit by an external emergency stop button (if the unit is equipped
with a local emergency stop button, external buttons can be connected in series)
• read a fault indication through a relay output
• communicate with the unit through a serial communication interface.
Refer to the circuit diagrams delivered with the drive for the connection terminals for
the external control devices.

Connection procedure

Open the cabinet door(s).
Remove the locking screws at the edge of the swing-out frame and open the frame.
Remove any shrouds that limit access to the cable lead-throughs and cable trunking.
Run the cables into the inside of the cabinet through the grommets provided.
Top entry units only: If several cables need to be run through one grommet, use Loctite 5221 (cat. no.
25551) under the grommet to seal the cable entry.
Run the cables to the appropriate terminals. Wherever possible, use the existing cable trunking in the
cabinet. Use sleeving wherever the cables are laid against sharp edges. When running cables to the
swing-out frame, leave some slack in the cable at the hinge to allow the frame to open fully. Tie the cables
to the cable supports wherever necessary.
Cut the cables to suitable length. Strip the cables and conductors.
Twist the cable shields into bundles and connect them to the ground terminal nearest to the terminal block.
Keep the unshielded portion of the cables as short as possible.
Connect the conductors to appropriate terminals (see chapter
circuit diagrams delivered with the unit).
Refit any shrouds removed earlier. Close the swing-out frame, refasten, and close the cabinet door(s).
