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.
To which products this chapter applies
This chapter applies to ACS800 units which employ RMIO-01 board from revision J
onwards and RMIO-02 board from revision H onwards.
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 terminal labelling
Optional modules (Rxxx) may have identical terminal designations with the RMIO
board.
