7.1
0x6040 Controlword
This provides the primary method of controlling the behavior of the drive e.g. enabling,
disabling, resetting, etc. Table 7.1 describes the format of the control word. The
individual bits are used in combinations (see Table 7.2) to sequence the drive through
the state machine described in Figure 7-1.
LEGEND: ms = manufacturer-specific; r = reserved; oms = operation mode specific; h = halt;
fr = fault reset; hos = homing operation start; eo = enable operation; qs = quick stop; ev =
enable voltage; so = switch on
