STEP – Differential step and direction outputs
The STEP option configures the ICM interconnect module with differential step and direction outputs. Single-ended
step and direction outputs are standard. See the individual ICM sections in Integrated Components for pinout
information.
Part number ordering example: DMC-4010-C012-I000(STEP)
Amplifier Enable Configurations
The default amplifier enable configuration for the ICM interconnect modules is 5V, HAEN, SINK. This is 5V logic,
high amplifier enable, and sinking. The amplifier enable configuration can be configured at the factory or in the
field. It is recommended that the correct amplifier enable configuration be ordered from the factory when using the
ICM-42000 (-I000) or the ICM-42100 (-I100). The Galil internal amplifiers will work with any amplifier enable
configurations set on the interconnect module.
See the Amplifier Interface section in Chapter 3 for more information.
Part number ordering example: DMC-4010-C012-I000(24V,HAEN,SINK)
5V – 5V Amplifier Enable Voltage
Uses the DMC-40x0 internal 5V for the amplifier enable circuit.
12V – 12V Amplifier Enable Voltage
Uses the DMC-40x0 internal 12V for the amplifier enable circuit.
24V – 24V Amplifier Enable Voltage
ICM is configured to be run from an external power supply of 13 -24VDC.
LAEN – Low Amplifier Enable
The controller sets the amplifier enable signal to logic low to enable the drive.
HAEN – High Amplifier Enable
The controller sets the amplifier enable signal to logic high to enable the drive.
SINK – Sinking Amplifier Enable
The amplifier will sink to controller ground with 5V and 12V options or to external supply ground when 24V is
ordered.
Source – Sourcing Amplifier Enable
The amplifier will source the internal 5V, 12V or the external 13-24V DC supply.
