enable/condition for Speed up and Speed
down to be used. If Speed up/down is used,
the speed change always follows ramp 2
(3-51 Ramp 2 Ramp Up Time and 3-52 Ramp
2 Ramp Down Time) in the range 0 -
parameter 1-23 Motor Frequency.
NOTICE
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 [2] Coast
inverse or [3] Coast and reset, inverse.
[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
parameter 3-41 Ramp 1 Ramp Up Time.
[22] Speed down
Same as [21] Speed up.
[23] Set-up select
bit 0
Selects one of the four set-ups. Set
0-10 Active Set-up to Multi Set-up.
[24] Set-up select
bit 1
Same as [23] Set-up select bit 0.
(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
Activates 14-10 Mains Failure. Mains failure
inverse is active in the Logic “0” situation.
[42] Ref source bit
0
An active input in bit 0 selects AI54 as the
reference source (see parameter group 3-1*
References, option [35] Digital input select).
An inactive input selects AI53.
[51] Hand/Auto
Start
Selects Hand or Auto Start. High = Auto On
only, Low = Hand on only.
[52] Run
Permissive
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.
[53] Hand start A signal applied will put the frequency
converter into Hand mode as if [Hand On]
has been pressed and a normal stop
command will be overridden. If discon-
necting 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. [Hand On]
and [Auto On] have no impact. [Off] will
override Hand Start and Auto Start. Press
either [Hand On] or [Auto On] 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] the motor
will stop regardless of signals on Hand Start
and Auto Start.
[54] Auto start A signal applied will put the frequency
converter into Auto mode as if [Auto On]
has been pressed. See also [53] Hand Start.
[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 Potenti-
ometer 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 parameter group 22-4*, Sleep Mode).
Reacts on the rising edge of signal applied!
[78] Reset
Preventive
Maintenance
Word
Resets all data in 16-96 Maintenance Word to
0.
[80] PTC Card1
All Digital Inputs can be set to [80] PTC Card
1. However, only one Digital Input must be
set to this choice.
