Motor control and I/O board (RMIO)

What this chapter contains

This chapter shows
• external control connections to the control board of the inverter unit with the
ACS800 standard control program (Factory macro)
• specifications of the inputs and outputs of the board.
Note: This chapter describes the standard I/O connections of the RMIO board
controlling the inverter unit. There is also another RMIO board which controls the
supply unit. The supply unit I/O connections are reserved for internal use (no
customer connections are possible or allowed). See chapter
for the description of the supply unit I/O interface.

Note on cabinet-installed ACS800 drives

The terminals of the RMIO board are optionally wired to terminal block X2. The
connections shown below apply also to terminal block X2 (the markings are identical
to the ones on the RMIO board).
Terminals of X2 accept cables from 0.5 to 4.0 mm
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 screwdriver with a blade thickness of 0.6 mm (0.024")
and width of 3.5 mm (0.138"), for example Phoenix Contact SZF 1-0,6X3,5.

Note on the terminal labelling

Optional modules (type Rxxx) may have terminal designations that coincide with
those of the RMIO board.
