Control interfaces

The following diagram shows the control interfaces and I/O options of the inverter
unit.
The front cover of frame R5i has a platform for the CDP 312R control panel; frames
R2i to R4i require an additional platform kit if the panel needs to be mounted on the
module.
For frame R6i to R8i (and multiples), the control panel is to be installed on a door
platform, available as a separate kit.

Optional module 1: I/O extension (RAIO,
RDIO), pulse encoder interface (RTAC), or
fieldbus adapter (e.g. RMBA, RDNA, RPBA)
Optional module 2: I/O extension (RAIO,
RDIO) or pulse encoder interface (RTAC)
Optional module 3: DDCS communication
option (RDCO-0x)
The fibre optic channels provided by the
RDCO module can be used for I/O extension
(using NAIO/NDIO modules), pulse encoder
connection (NTAC module), fieldbus
connection (Nxxx fieldbus adapter modules),
