Parameter Description
[20] Freeze output Freezes actual motor frequency (Hz). The
frozen motor frequency is now the point of
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 - 1-23 Motor Frequency.
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 [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 3-41 Ramp 1 Ramp
Up Time.
[22] Speed down Same as [21] Speed up.
[23] Set-up select Selects one of the four set-ups. Set
bit 0 0-10 Active Set-up to Multi Set-up.
[24] Set-up select Same as [23] Set-up select bit 0.
bit 1 (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 Activates 14-10 Mains Failure. Mains failure
inverse inverse is active in the Logic "0" situation.
[51] Hand/Auto Selects Hand or Auto Start. High = Auto On
Start only, Low = Hand on only.
[52] Run The input terminal, for which the Run
Permissive 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 5-4* Relays, will not be affected by
Run Permissive.
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.
A signal applied will put the frequency
converter into Auto mode as if [Auto On]
has been pressed. See also [53] Hand Start.
