4-76 LiquiFlo 1.5 AC Drive, Software Reference Version 1.2
4 = Stop - CF (Stop - Clear Faults): An open input will always assert a stop
command. While the stop is asserted, the drive ready status will be off. A closed input
will allow the drive to start. An open-to-closed transition is interpreted as a clear faults
request. The drive will clear 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 the terminal block
is the control source.
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
the terminal block is the control source. A closed input sets the direction to reverse. If
the state of the input changes and the drive is running or jogging, the drive will change
direction.
If the Fwd/Rev input function is assigned to more than one physical digital input at a
time, a digital input configuration alarm will be asserted.
7 = Run: An open-to-closed transition on this input generates a a run command if the
terminal block is the control source. 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 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 - 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 will be asserted.
10 = Jog: An open-to-closed transition on this input while the drive is stopped causes
the drive to start (jog) in the current direction. When the input opens while the drive is
running (jogging), the drive will stop.
The drive will not jog while running or while the Stop - Clear Faults input is open. Start
has precedence over jog.
11 and 12 = Jog Forward and Jog Reverse: An open-to-closed transition on one or
both inputs while the drive is stopped will cause the drive to jog unless the Stop - Clear
Faults input function is configured and open. Table 4.5 on page 77 describes the
actions taken by the drive in response to various states of these input functions.
!
ATTENTION: If a normal drive start command is received while the drive
is jogging, the drive will switch from jog mode to run mode. The drive will
not stop, but may change speed and/or change direction. Failure to
observe this precaution could result in severe bodily injury or loss of life.
