and reset. (See Unidrive manual for more information.)
Some example control word values for the Unidrive are given in the

the display will show "Inh" when set at 0, and depends on
#6.30 and #6.32 when set to 1. Setting #6.15 to 0 overrides
#6.30 and #6.32, and immediately disables the Unidrive.
The motor will coast to rest if it is running when the Unidrive
is disabled.

direction signals.
