Run Forward and Run Reverse. If the terminal block is the control source, an
open-to-closed transition on one or both inputs while the drive is
stopped will cause the drive to run unless the Stop – CF input
function is configured and open.
If one or both of these input functions are assigned to more than
one physical digital input at a time, a digital input configuration
alarm will be asserted.
Stop Mode B This digital input selects between two different drive stop modes.
If the input is open, then Stop Mode A selects which stop mode
to use. If the input is closed, the Stop Mode B selects which stop
mode to use. If this input function is not configured, then Stop
Mode A selects which stop mode to use.
Bus Reg Md B This digital input function selects how the drive will regulate
excess voltage on the DC bus.
If the input is open, then Bus Reg Mode A selects which bus
regulation mode to use. If the input is closed, then Bus Reg
Mode B selects which bus regulation mode to use. If this input
function is not configured, then Bus Reg Mode A selects which
bus regulation mode to use.
Speed Sel 1-3 One, two, or three digital input functions can be used to select
the Speed Select input function used by the drive. The open/
closed state of all Speed Select input functions combine to
select the speed reference.
There are seven possible combinations of open/closed states for
the three input functions: Speed Ref A Sel, Preset Speed 1-6,
and Purge Speed.
If the Speed Select input functions select Speed Ref A Sel, then
the value of that parameter further selects a reference source.
There are a large number of possible selections, including all
five presets.
If the input functions directly select one of the preset speed
parameters, then the parameter contains a frequency that is to
be used as the reference.
The Speed Select input function configuration process involves
assigning the functionality of the three possible Speed Select
input functions (Speed Sel 1-3) to physical digital inputs.
The table below describes the various reference sources that
can be selected using all three of the Speed Select input
functions. If any of the three Reference Select input functions
are not configured, then the software will still follow the table, but
will treat the unconfigured inputs as if they are permanently
open.
