Hardware description

Overview

Option +P906 allows the drive control unit to be installed separately from the main drive
module, for instance in a separate compartment. The external control unit option makes
the drive module removal easier, as the customer control cabling can stay in place while
the module is removed.
Several cables connect the control unit and the drive:
•
1 × 24 V power supply cable (with a ground connection)
•
2 × Safe Torque Off (STO) cables
•
1 × pair of optical cables for all major inverter power stack communication.
These cables are supplied with the module and come with plugs and sockets that allow
disconnection at either end.
