B091/B088: Stop Mode / Restart Mode Configuration – You can configure how the
inverter performs a standard stop (each time Run FWD and REV signals 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
frequency matching). The Run command may turn OFF briefly, allowing the motor to
coast to a slower speed from which normal operation can resume.
