2.5.3. Encoder Monitor

Both encoder interfaces are equipped with a monitoring circuit that can detect open circuit as well
as short circuit of each encoder channel. Each encoder channel has a LED showing the status:
Green light means OK, no light means fault. An encoder fault will result in an "Option error" 192
if encoder monitoring is activated via parameter 3239 (master) and 3209 (slave).

2.5.4. Option Card Layout

MCO 350 control terminals are plug connectors with screw terminals; the terminal blocks are
duplicated to enable use of the same MCO 350 in all frame sizes. See illustration to locate the
terminal blocks:
