Control of the inverter unit and motor
As standard, the drive is equipped with one control panel (type CDP-312R) on the
inverter module cubicle door. The user controls the motor with this control panel or
through fieldbus when the control unit of the inverter unit is equipped with an optional
fieldbus adapter module.
Control panel
The control panel is the user interface of the supply and inverter units of the drive,
providing the essential controls such as Start/Stop/Direction/Reset/Reference, and
the parameter settings for the control programs. The suffix “LM” on the control panel
display denotes ACS800-17LC. More information on using the panel can be found in
the inverter unit firmware manual delivered with the drive.
The control panel is wired to the supply unit and inverter unit using a Y-splitter.
Connections and use of the I/O in the inverter unit

Circuit boards
1)
The RDCU is equipped with an auxiliary power interface board (RAPI) when not equipped with
terminals for connecting external control voltage (option +G307). The RAPI ensures that the “POWER
FAIL” function of the RMIO board can be carried out in case the 24 V auxiliary power to the RDCU is
interrupted ie, the fault and alarm loggers have enough time to write collected data into the flash
memory.
Abbr. Description
RDCU Drive control unit. Note that in units with several modules in parallel, there is a branching
unit (APBU or NPBU) between the modules and the control unit.
