Selection of Setup, Selection of Setup, Selection of Setup, enables a choice of one of the Selection of Setup, Selection of Setup,
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 is selected if the reference
Catch-up/Slow-down Catch-up/Slow-down
value is to be increased or reduced by a
programmable percentage value set in parameter
219.

Preset reference Preset reference enables a choice of one of the Preset reference
Preset reference Preset reference
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 corrects the ramp-down time to
Precise stop Precise stop
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
parameter 204. The frequency is set in parameter
327, corresponding to Ref
Pulse feedback Pulse feedback
Pulse feedback Pulse feedback is selected if a pulse sequence Pulse feedback
(frequency) is selected as a feedback signal.
Analog reference Analog reference Analog reference Analog 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.

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
4.0 mA
H,I
0.0 mA
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
20.0 mA
Function:
,
MIN
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.
