Function description
The Remote Speed Reference function is part of the Speed Reference Generation
function. It forms a speed reference signal from the remote source (typically a
system level controller or an adjustable analog input).
The Remote Speed Reference function produces a local speed reference that becomes
the speed reference used by the Speed Reference Generation function if the drive is
in remote mode (when Local mode active is False). Remote mode is enabled using
the DDI Remote/Local button.
The remote speed reference is formed by selecting an automatic or manual reference.
The automatic reference is usually a signal from a system level controller. The
manual reference is usually an analog input signal or a constant setpoint. The
selection of the automatic or manual reference source is determined by Auto mode
select. If the variable selected by Auto mode select is True, then the automatic
reference is used. If the variable selected by Auto mode select is False, then the
manual reference is used.
If the automatic reference is used, then the remote speed reference is set equal to the
signal selected by Auto analog ref sel.
If the manual speed reference is used, then the remote speed reference is set to either
a selectable or a constant value, depending on the value of Manual speed ref sel. If
Manual speed ref sel is False, then the remote reference is set equal to the signal
selected by Man analog ref sel. If Manual speed ref sel is True, then the remote
reference is set equal to Speed setpoint 0.
The selection of the remote speed reference described in the preceding paragraphs
applies when Jog request is False. When Jog request is True, the remote speed
reference is set to the value of Remote jog speed. More information on Jog request is
available in the Sequencer Commands function help.

Speed Reference Generation
The Speed Reference Generation function coordinates the activities involved in
selecting and processing the speed reference signal.
Function description
The Speed Reference Generation function selects the speed reference signal from a
local or remote source. The local source is the DDI/keypad (details on forming the
local reference are available in the Local Speed Reference function help). The remote
source is typically a system level controller or an adjustable analog input.
Information on the formation of the remote reference is available in the Remote
Speed Reference function help.
The Speed Reference Generation selects the local reference if Local mode active is
True. It selects the remote reference if Local mode active is False. Select the value
of Local mode active with the DDI Remote/Local button.
