Selection of Setup, Selection of Setup, Selection of Setup, Selection of Setup, Selection of Setup, enables a choice of one of the
two Setups; however, this presupposes that
parameter 004 has been set to Multi Setup.
Catch-up/Slow-down Catch-up/Slow-down Catch-up/Slow-down Catch-up/Slow-down Catch-up/Slow-down is selected if the reference
value is to be increased or reduced by a
programmable percentage value set in parameter
219.
Slow-down Catch-up
Unchanged speed 0 0
Reduced by %-value 1 0
Increased by %-value 0 1
Reduced by %-value 1 1
Preset reference Preset reference Preset reference Preset reference Preset reference enables a choice of one of the two
preset references, in accordance with the table in
parameter 215 and 216. To be active, Preset
reference, on has to be selected.
Preset reference, on Preset reference, on Preset reference, on Preset reference, on Preset reference, on is used for shifting between
external reference and preset reference. It is assumed
that External/preset [2] has been selected in
parameter 214. Logic '0' = external references active;
logic '1' = one of the two preset references is active.
Precise stop Precise stop Precise stop Precise stop Precise stop corrects the ramp-down time to obtain a
high repetitive accuracy of the stopping point.
Pulse reference Pulse reference
Pulse reference Pulse reference
Pulse reference is selected if a pulse sequence
(frequency) of 0 Hz is used, corresponding to Ref
MIN
,
parameter 204. The frequency is set in parameter
327, corresponding to Ref
MAX
.
Pulse feedback Pulse feedback
Pulse feedback Pulse feedback Pulse feedback is selected if a pulse sequence
(frequency) is selected as a feedback signal. See
also page 50.
Analogue reference Analogue reference Analogue reference Analogue reference Analogue reference is selected to enable change of
reference by means of an analogue reference signal.
See also page 50.
If other inputs are connected, these are added up,
taking account of their signs.
Analogue feedback Analogue feedback Analogue feedback Analogue feedback Analogue feedback is selected if closed loop
regulation with an analogue signal is used.
Reset and start Reset and start
Reset and start Reset and start Reset and start is used for activating start at the
same time as reset.
Scaling of the input signal is effected in parameters
338 and 339.
NB!
If Reference or Feedback has been selected
on more than one terminal, these signals will
be added with signs.
336 Terminal 1, min. scaling
(AI 1 SCALE LOW)
Settings:
0.0 - 20.0 mA [0 - 200]
★
0.0 mA [0]
Function:
This parameter determines the value of the reference
signal that is to correspond to the minimum reference
value set in parameter 204.
If the Time-out function of parameter 317 is to be
used, the setting must be > 2 mA.
Description of choice:
Set the desired current value.
337 Terminal 1, max. scaling
(AI 1 SCALE HIGH)
Setting:
0.0 - 20.0 mA [0 - 200]
★
20.0 mA [200]
Function:
This parameter sets the value of the reference signal
that is to correspond to the maximum reference value
set in parameter 205.
Description of choice:
Set the desired current value.
338 Terminal 2, min. scaling
(AI 2 SCALE LOW)
Settings:
0.0 - 10.0 V [0 - 100]
★
0.0 V [0]
Function:
This parameter is used for setting the signal value that
corresponds to the minimum reference value set in
parameter 204.
Description of choice:
Set the desired voltage value.
