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
is selected if the reference
value is to be increased or reduced by a
programmable percentage value set in parameter
219.

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, onPreset reference, on
Preset reference, onPreset 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 stopPrecise stop
Precise stopPrecise stop
Precise stop corrects the ramp-down time to
obtain a high repetitive accuracy of the stopping
point.
Pulse referencePulse reference
Pulse referencePulse 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 feedbackPulse feedback
Pulse feedbackPulse feedback
Pulse feedback is selected if a pulse sequence
(frequency) is selected as a feedback signal.
Analog referenceAnalog reference
Analog referenceAnalog reference
Analog reference
is selected to enable change of
reference by means of an analog reference signal.
If other inputs are connected, these are summed,
taking account of their signs.
Analog feedback Analog feedback
Analog feedback Analog feedback
Analog feedback is selected if closed loop
regulation with an analog 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.

If Reference or Feedback has been selected on
more than one terminal, these signals will be
summed with signs.
336 Terminal 1, min. scaling
(AI 1 SCALE LOW)
Settings:
0.0 - 20.0 mA [0 - 200]
H,I 4.0 mA [40]
★ 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.
