ICM-2900 Interconnect Module
The ICM-2900 interconnect module provides easy connections between the DMC-13X8 series
controllers and other system elements, such as amplifiers, encoders, and external switches. The ICM-
2900 accepts the 100-pin main cable and provides screw-type terminals for connections. Each screw
terminal is labeled for quick connection of system elements. The ICM-2900 provides access to all 4
axes of signals. The ICM-2900 does not provide connection to the auxiliary encoders. Connections to
the auxiliary encoders may be made through the ICM-2908.
