Note When 01 is set on b180, and key is pressed, initialization starts immedi-
ately and there is not any way to restore the previous parameter setting. MX2
doesn't have a method to trigger the initialization by key action as others
Omron inverter models have.
Stop Mode/Restart Mode Configuration: B091/B088 – You can configure
how the inverter performs a standard stop (each time Run FWD and REV sig-
nals turn OFF). Setting B091 determines whether the inverter will control the
deceleration, or whether it will perform a free-run stop (coast to a stop). When
using the free-run stop selection, it is imperative to also configure how you
want the inverter to resume control of motor speed. Setting B088 determines
whether the inverter will ensure the motor always resumes at 0 Hz, or whether
the motor resumes from its current coasting speed (also called active fre-
quency matching). The run command may turn OFF briefly, allowing the
motor to coast to a slower speed from which normal operation can resume.

tered parameters in Uxxx and
