Danfoss VLT 5000 Series Operating Instructions Manual page 116

See also parameter 205.
NB!:
The output frequency of the frequency converter
can never assume a value higher than 1/10
of the switching frequency.
Description of choice:
A value from f to the choice made in parameter
MIN
200 can be selected.
NB!:
If the maximum motor frequency is set at
more than 500 Hz, parameter 446 must be
set at 60° AVM [0] switching pattern.
203 Reference/feedback area
(REF/FEEDB. RANGE)
Value:
Min - Max (MIN - MAX)
- Max - + Max (-MAX-+MAX)
Function:
This parameter decides whether the reference
signal and the feedback signal are to be positive
or can be both positive and negative.
The minimum limit may be a negative value, unless
Speed control, closed loop has been selected
(parameter 100).
Choose Min - Max [0] if Process control, closed loop
has been selected in parameter 100.
Description of choice:
Choose the desired range.
204 Minimum reference
(MIN. REFERENCE)
Value:
-100,000.000 - Ref
MAX
Depends on parameter 100.
Function:
The Minimum reference gives the minimum value
that can be assumed by the sum of all references.
Minimum reference is only active if Min - Max [0] has
been set in parameter 203; however, it is always active
in Process control, closed loop (parameter 100).
Description of choice:
Is only active when parameter 203 has been
set to Min - Max [0].
Set the desired value.

The unit follows the choice of configuration
in parameter 100.
Speed control, open loop:
Speed control, closed loop:
Torque control, open loop:
Torque control, speed feedback:
Process control, closed loop:
Special motor characteristics, activated in parameter
101, use the unit selected in parameter 100.
205 Maximum reference
(MAX. REFERENCE)
Value:
Ref - 100,000.000
MIN
[0]
Function:
[1]
The Maximum reference gives the highest value that
can be assumed by the sum of all references. If
closed loop has been selected in parameter 100,
the maximum reference cannot be set higher than
the maximum feedback (parameter 415).
Description of choice:
Set the desired value.
The unit follows the choice of configuration
in parameter 100.
Speed control, open loop:
Speed control, closed loop:
Torque control, open loop:
Torque control, speed feedback:
Process control, closed loop:
Special motor characteristics, activated in parameter
0.000 101, use the unit selected in parameter 100.
206 Ramp type (RAMP TYPE)
Value:
Linear (LINEAR)
Sinusoidal (S1)
2
Sin (S2)
3
Sin (S3)
2
Sin filter (S2 FILTER)
Function:
There is a choice of 4 different ramp types.
