VLT AQUA Low Harmonic Drive Operating Instructions
When Freeze output is active, the frequency
converter cannot be stopped via a low
'start [13]' signal. Stop the frequency
converter via a terminal programmed for
Coasting inverse [2] or Coast and reset,
inverse [3].
For digital control of the up/down speed is
desired (motor potentiometer). Activate this
function by selecting either Freeze
reference or Freeze output. When Speed up
is activated for less than 400 msec. the
resulting reference will be increased by 0.1
%. If Speed up is activated for more than
400 msec. the resulting reference will ramp
according to Ramp 1in 3-41 Ramp 1 Ramp
Up Time.
Same as Speed up [21].
Selects one of the four set-ups. Set
0-10 Active Set-up to Multi Set-up.
Same as Set-up select bit 0 [23].
(Default Digital input 32)
Select Pulse input when using a pulse
sequence as either reference or feedback.
Scaling is done in parameter group 5-5*.
Select which ramp to use. Logic "0" will
select ramp 1 while logic "1" will select
ramp 2.
Activates 14-10 Mains Failure. Mains failure
inverse is active in the Logic "0" situation.
The input terminal, for which the Run
permissive has been programmed must be
logic "1" before a start command can be
accepted. Run permissive has a logic 'AND'
function related to the terminal which is
programmed for [8] Start, [14] Jog or [20]
Freeze Output, which means that in order to
start running the motor, both conditions
must be fulfilled. If Run Permissive is
programmed on multiple terminals, Run
permissive needs only be logic '1' on one
of the terminals for the function to be
carried out. The digital output signal for
Run Request ([8] Start, [14] Jog or [20]
Freeze output) programmed in parameter
group 5-3* Digital outputs, or parameter
group 5-4* Relays, will not be affected by
Run Permissive.
A signal applied will put the frequency
converter into Hand mode as if button
[Hand On] on the LCP has been pressed
and a normal stop command will be
overridden. If disconnecting the signal, the
motor will stop. To make any other start
commands valid, another digital input must
be assign to Auto Start and a signal applied
to this. The [Hand On] and [Auto On]
buttons on the LCP has no impact. The Off

button on the LCP will override Hand Start
and Auto Start. Press either the [Hand On]
or [Auto On] button to make Hand Start and
Auto Start active again. If no signal on
neither Hand Start nor Auto Start, the motor
will stop regardless of any normal Start
command applied. If signal applied to both
Hand Start and Auto Start, the function will
be Auto Start. If pressing [Off] on the LCP
the motor will stop regardless of signals on
Hand Start and Auto Start.
A signal applied will put the frequency
converter into Auto mode as if the LCP key
[Auto On] has been pressed. See also [53]
