A7 – ICM-42100 (-I100)
Description
The ICM-42100 option resides inside the DMC-40x0 enclosure and accepts sinusoidal encoder signals instead of
digital encoder signals as accepted by the ICM-42000. The ICM-42100 provides interpolation of up to four 1-volt
differential sinusoidal encoders resulting in a higher position resolution. The AFn command selects sinusoidal
interpolation where n specifies 2
n
interpolation counts per encoder cycle (n=5 to 12). For example, if the encoder
cycle is 40 microns, AF10 results in 2 10 =1024 counts per cycle, or a resolution of 39 nanometers per count. With the
ICM-42100, the sinusoidal encoder inputs replace the main digital encoder inputs. The ICM-42100 provides a 15-
pin D-sub connector for the encoders on each axis, a 15-pin D-sub for analog inputs, a 44-pin D-sub for I/O, and a
44-pin D-sub for the motor command signals. Two ICMs are required for 5- thru 8-axis controllers.
Note: Hardware Rev B of the the ICM-42100 supports the use of standard differential quadrature encoders
for axes that will not be using the sinusoidal encoders. A standard ICM-42100 does not support the
use of single ended quadrature encoders. Contact Galil if a single ended quadrature encoder is
required when using the ICM-42100, or if you require encoder inputs with a Rev A ICM-42100
The ID command will indicate the hardware Rev of the ICM-42100 where Rev B will return Rev 1 and
Rev A will return Rev 0. A typical response from ID with a ICM-42100 Rev B is shown below.
