Operating instructions

change always follows ramp 2 (par. 3-51 Ramp 2
Ramp Up Time and par. 3-52 Ramp 2 Ramp Down
Time) in the range 0 - par. 1-23 Motor Frequen-
cy.
NOTE
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].
[21] Speed up 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 1 in par. 3-41 Ramp
1 Ramp Up Time.
[22] Speed
down
Same as Speed up [21].
[23] Set-up
select bit 0
Selects one of the four set-ups. Set par. 0-10 to
Multi Set-up.
[24] Set-up
select bit 1
Same as Set-up select bit 0 [23].
(Default Digital input 32)
[32] Pulse input Select Pulse input when using a pulse sequence
as either reference or feedback. Scaling is done
in parameter group 5-5*.
[34] Ramp bit 0 Select which ramp to use. Logic “0” will select
ramp 1 while logic “1” will select ramp 2.
[36] Mains
failure
inverse
Select to activate function selected in
par. 14-10 Mains Failure. Mains failure is active in
the Logic “0” situation.
[37] Fire mode A signal applied will put the frequency convert-
er into Fire Mode and all other commands will
be disregarded. See 24-0* Fire Mode.
[52] Run Permis-
sive
The input terminal, for which the Run permissive
has been programmed must be logic “1” before
a start command can be accepted. Run permis-
sive has a logic ‘AND’ function related to the
terminal which is programmed for START [8], Jog
[14] or Freeze Output [20], which means that in
order to start running the motor, both
conditions must be fulfilled. If Run Permissive is
programmed on multiple terminals, Run permis-
sive needs only be logic ‘1’ on one of the
terminals for the function to be carried out. The
digital output signal for Run Request (Start [8],
Jog [14] or Freeze output [20]) programmed in
par. 5-3*, or par. 5-4*, will not be affected by Run
Permissive.
NOTE
If no Run Permissive signal is applied
but either Run, Jog or Freeze
commands is activated, the status line
in the display will show either Run
Requested, Jog Requested or Freeze
Requested.
[53] Hand start A signal applied will put the frequency convert-
er 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 the Off button on
the LCP the motor will stop regardless of signals
on Hand Start and Auto Start.
[54] Auto start A signal applied will put the frequency convert-
er into Auto mode as if the LCP button Auto On
has been pressed. See also Hand Start [53]
[55] DigiPot
Increase
Uses the input as an INCREASE signal to the
Digital Potentiometer function described in
parameter group 3-9*
[56] DigiPot
Decrease
Uses the input as a DECREASE signal to the
Digital Potentiometer function described in
parameter group 3-9*
[57] DigiPot
Clear
Uses the input to CLEAR the Digital Potentiome-
ter reference described in parameter group 3-9*
[60] Counter A
(up)
(Terminal 29 or 33 only) Input for increment
counting in the SLC counter.
[61] Counter A
(down)
(Terminal 29 or 33 only) Input for decrement
counting in the SLC counter.
[62] Reset
Counter A
Input for reset of counter A.
[63] Counter B
(up)
(Terminal 29 and 33 only) Input for increment
counting in the SLC counter.
[64] Counter B
(down)
(Terminal 29 and 33 only) Input for decrement
counting in the SLC counter.
[65] Reset
Counter B
Input for reset of counter B.
[66] Sleep Mode Forces frequency converter into Sleep Mode
(see par. 22-4*). Reacts on the rising edge of
signal applied!
[78] Reset
Preventive
Mainte-
nance
Word
Resets all data in par. 16-96 Maintenance Word
to 0.
