Danfoss VLT 5000 Series, Instruction Manual, Page: 104 / 240

5032-5052 200-240 V, VLT 5122-5552 380-500 V and
5042-5602 525-690 V the factory setting is 66 Hz.
See also parameter 205.
NOTE
The output frequency of the adjustable
frequency drive can never assume a value
higher than 1/10 of the switching frequen-
cy.
Description of choice:
A value from f
MIN
to the choice made in parameter 200
can be selected.
NOTE
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) [0]
- Max - + Max (-MAX-+MAX) [1]
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
0.000
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 Proc-
ess 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 param-
eter 100.
Speed control, open loop: Hz
Speed control, closed loop: rpm
Torque control, open loop: Nm
Torque control, speed feedback: Nm
Process control, closed loop: Process units
(par. 416)
Special motor characteristics, activated in parameter
101, use the unit selected in parameter 100.
205 Maximum reference
(MAX. REFERENCE)
Value:
Ref
MIN
- 100,000.000
50.000
Function:
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 maxi-
mum reference cannot be set higher than the maxi-
mum feedback (parameter 415).
Description of choice:
Set the desired value.
The unit follows the choice of configuration in param-
eter 100.
Speed control, open loop: Hz
Speed control, closed loop: rpm
Torque control, open loop: Nm
Torque control, speed feedback: Nm
Process control, closed loop: Process units
(par. 416)
Special motor characteristics, activated in parameter
101, use the unit selected in parameter 100.
