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 the
chapter Motor control and I/O board (RMIO).
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.
