Motor control and I/O board (RMIO)
What this chapter contains
This chapter shows
• external control connections to the RMIO board for the ACS800 Standard Control
Program (Factory Macro)
• specifications of the inputs and outputs of the board.
Note on terminal labelling
Option modules (Rxxx) may have identical terminal designations with the RMIO
board.
Note on external power supply
External +24 V DC power supply for the RMIO board is recommended if
• the application requires a fast start after connecting the input power supply
• fieldbus communication is required when the input power supply is disconnected.
The RMIO board can be supplied from an external power source via terminal X23 or
X34 or via both X23 and X34. The internal power supply to terminal X34 can be left
connected when using terminal X23.
WARNING! If the RMIO board is supplied from an external power source via
terminal X34, the loose end of the cable removed from the RMIO board terminal
must be secured mechanically to a location where it cannot come into contact with
electrical parts. If the screw terminal plug of the cable is removed, the wire ends
must be individually insulated.
Parameter settings
In Standard Control Program, set parameter 16.9 CTRL BOARD SUPPLY to
EXTERNAL 24V if the RMIO board is powered from an external supply.
