Selected Parameters
Command Enable (Bit 8) : A 1-bit field used to select one of the
three logic commands in the Drive. For details see table 7.D.
If the command enable bit is set to 1 in Logic Command 3, then
Logic Command 3 is the active logic command accepted by the
Drive. If the command enable bit in logic command 3 is set to 0, then
the Logic Command 1 is checked. If the command enable in Logic
Command 1 is set to 1, then Logic Command 1 is the active logic
command accepted by the drive. If the command enable in Logic
Command 1 is set to 0, the Logic Command 2 is the active logic
command accepted by the Drive. The Logic Command 2 enable bit is
ignored.

A Stop request from any Logic Command word will always be
acknowledged, regardless of the state of the command enable bit.
J og 2 (Bit 9) : A 1-bit field specifying the drive to select the Jog 2
Speed (Parameter 639). When set to 1, the contactor will close and
velocity regulation will begin.
The drive will continue to run using the Jog 2 Speed reference until
this bit is set to 0. At this time, velocity reference will be set to zero
and the drive will regenerate to a stop. Once the motor has stopped,
velocity regulation will stop. The contactor will remain closed for the
time specified by Jog Dwell (Parameter 711). The ramp function can
be selected while jogging by properly programming JOG RAMP
ENABLE (Parameter 626).
Jog 1 (Bit 10) : A 1-bit field specifying the drive to select the Jog 1
Speed (Parameter 638). When set to 1, the contactor will close and
velocity regulation will begin.
