173 [DPI Loss Action]

Selects the speed reference that will be selected
when a “DPI Px Loss” alarm occurs on the HIM
that is providing the speed reference.
“Hold OutFreq” (1) - selects the last HIM
commanded speed reference.
“Goto Preset1” (2) - selects the value that was
saved in parameter 101 - [Preset Speed 1].
Important: The HIM reference is not retained if
power is lost or removed.
NOTE: The user must verify that the HIM is not
the sole stopping source and that an alternate
stop source is available. If the HIM is the sole
stopping source and it is disconnected, the drive
will fault regardless of the configuration in
parameter 238 [Fault Config 1].
NOTE: To avoid or override a DPI loss fault and
keep the drive running, change the respective bit
that corresponds to the DPI port (bits 16…18) in
parameter 238 [Fault Config 1] to a value of “0”
to disable the fault.

193 [Man Ref Preload]

Enables/disables a feature to automatically load
the present “Auto” frequency reference value into
the HIM when “Manual” is selected. Allows
smooth speed transition from “Auto” to
“Manual.”
