The Basic Line Module receives its control information via DRIVE-CLiQ from:

• CU320-2 Control Unit
• SINUMERIK 840D sl with
  • NCU 710.3 PN
  • NCU 720.3 PN
  • NCU 730.2 PN
  • Numeric Control Extensions NX10.3/NX15.3

Note: The thermostatic switch built into the braking resistor must be looped into the shutdown chain of the drive to prevent thermal overloading of the system in the event of a fault. If a braking resistor is not connected, a jumper must be connected between X21.1 and X21.2.
