6.2.2 Command Assemblies
Command assemblies contain a control word and several fields used for setting values, requesting response
data, and commanding moves. A command assembly may be used to send one data command at a time (tar-
get position, target velocity, acceleration, deceleration or torque). The command type is specified in the Com-
mand Type field. A command assembly also specifies a Response Type, requesting a particular kind of data
in the response assembly.
A command assembly may contain both a Command Type and a Response Type to transmit a command and
request a particular response in the same assembly.
A valid Command Type is required to be set in each command assembly. Data outside the allowed range will
result in an Error Response Assembly.
The amplifier must be homed before motion is begun in position mode. Failure to home the amplifier will result
in a fault that must be cleared before amplifier operation can continue.

Control Word
The control word contains bits for enabling, moving, and handshaking with the
drive.
