3.2.5. Control unit (COU)
The COU incorporates the hardware for the control, monitoring and protection
functions of the drive, and the communication interfaces to the local control panel
and to the remote control hardware.
3.2.5.1. COU versions
The number of COUs in the drive depends on the configuration and application of
the drive:
– Typically, an ARU in combination with an inverter unit (INU) shares the control
unit of the first INU.
Depending on the selected options and the configuration of the drive, a
separate control unit is used for the ARU.
If an LSU is part of the drive, all rectifier- and line-related functions are
implemented in the control unit of the INU.
– A separate control unit is assigned to each INU that supplies a single motor.
– If several INUs supply one motor, they share one control unit.
For information on the number of control units and their location in the drive, see
“Appendix C - Mechanical drawings”.
The hardware components of a COU are fitted on a swing frame. The size of the
swing frame and the mounting position of the components depend on the cabinet
version where the swing frame is installed in Fig. 3-11.
