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
Application Program (Factory Macro)
• specifications of the inputs and outputs of the board.
To which products this chapter applies
This chapter applies to ACS800 units which employ the RMIO board.
Note for the ACS800-02 with enclosure extension and the ACS800-07
The connections for the RMIO board shown below apply also to optional terminal
block X2 available for the ACS800-02 and ACS800-07. The terminals of the RMIO
board are wired to terminal block X2 internally.
Terminals of X2 accept cables from 0.5 to 4.0 mm
2
(22 to 12 AWG). Tightening
torque for screw terminals is 0.4 to 0.8 Nm (0.3 to 0.6 lbf ft). For disconnecting wires
from spring terminals, use a screw driver with a blade thickness of 0.6 mm
(0.024 in.) and width of 3.5 mm (0.138 in.), e.g. PHOENIX CONTACT SZF 1-
0,6X3,5.
Note on external power supply
WARNING! If the RMIO board is supplied from an external power source, 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.
