B084, B085: Initialization codes –
These functions allow you to restore the factory default
settings. Please refer to
“Restoring Factory Default Settings” on page 6–16
.
B086: Frequency display scaling –
You can convert the output frequency monitor on D001 to
a scaled number (engineering units) monitored at function D007. For example, the motor may
run a conveyor that is monitored in feet per minute. Use this formula:
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 deter-
mines 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.
In most applications a controlled deceleration is desirable, corresponding to B091=00.
However, applications such as HVAC fan control will often use a free-run stop (B091=01). This
practice decreases dynamic stress on system components, prolonging system life. In this case,
you will typically set B088=01 in order to resume from the current speed after a free-run stop
(see diagram below, right). Note that using the default setting, B088=00, can cause trip events
when the inverter attempts to force the load quickly to zero speed.
