DMC-31000
Description
The DMC-31000 is an option that allows for the controller to accept sinusoidal encoder signals in addition to
standard, differential quadrature encoder signals
1
. The DMC-31000 option can provide interpolation for a single 1
V
pk-pk
differential sinusoidal encoder resulting in a higher position resolution. The AF command is used to select the
degree of interpolation, see AF in the Command Reference for more details.

NOTE
The DMC-31000 options
requires
differential signals if using a quadrature encoder.
See the
ID
command in the Command Reference for board identification.
When wiring either Sin/Cos
or
standard differential encoders on an axis will use the same pins, see Table 5.10 for
pin-outs.
The DMC-31000 requires specific firmware for the implementation of Sin/Cos encoders. Any unit ordered with this
option will automatically be loaded with this firmware at the factory. With this firmware, the maximum speed
settings will be increased from 22,000,000 [cts/s] to 50,000,000 [cts/s]. See the DMC-3x01x User Manual for more
information.
Analog Inputs
With the DMC-31000 the analog inputs are upgraded to 16-bit, ±10V configurable. See the DMC-3x01x User
Manual for more information.
