Parameter Descriptions Chapter 9
If this input is configured at the same time as Stop-Clear Faults, then only the
Clear Faults input can actually cause faults to be reset.
3 = Aux Fault: If the input is open, an Auxiliary Input fault (fault 2) is generated.
The Aux Fault Input Function is active at all times regardless of the selected logic
control source.
4 = Stop - CF (Stop - Clear Faults): An open input always asserts a stop
command. While the stop is asserted, the drive ready status is off. A closed input
allows the drive to start. An open-to-closed transition is interpreted as a clear
faults request. The drive clears any existing faults.
If Start is configured, then Stop - Clear Faults must also be configured to prevent
a digital input configuration alarm condition. Stop - Clear Faults is optional in all
other circumstances.
5 = Start: An open-to-closed transition generates a run command if start from
the terminal block is enabled via the Logic Mask (276) and Start Mask (277).
If Start is configured, then Stop - Clear Faults must also be configured to prevent
a digital input configuration alarm condition.
6 = Fwd/Reverse (Forward/Reverse): An open input sets the direction to
forward if direction control from the terminal block is enabled via the Logic
Mask (276) and Direction Mask (279). A closed input sets the direction to
reverse. If the state of the input changes and the drive is running or jogging, the
drive changes direction.
If the Fwd/Rev input function is assigned to more than one physical digital input
at a time, a digital input configuration alarm is asserted.
7 = Run: An open-to-closed transition on this input generates a a run command
if start from the terminal block is enabled via the Logic Mask (276) and Start
Mask (277). If the input is open, the drive will stop.
The purpose of this input function is to allow a 2-wire start while the direction is
being controlled by some other function.
8 and 9 = Run Forward and Run Reverse: If start and direction control from
the terminal block are enabled via the Logic Mask (276), Start Mask (277), and
Direction Mask (279), an open-to-closed transition on one or both inputs while
the drive is stopped causes the drive to run unless the Stop - Clear Faults 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 is asserted.
IMPORTANT The Aux Fault input function is not intended for a fast output power kill. The
drive will not fault until the software detects the change of state of this input.
If this input function is not configured, the fault will not occur.
