Parameters — References and limits
201 Output frequency low limit (F
(OUT FREQ LOW LIM)
Value:
0.0 - f
MAX
Function:
In this parameter, a minimum motor frequency limit
can be selected that corresponds to the minimum
frequency at which the motor is to run.
The minimum frequency can never be higher than
the maximum frequency, f
If Both directions has been selected in parameter 200,
the minimum frequency is of no significance.
Description of choice:
A value from 0.0 Hz to the max. frequency selected
in parameter 202 (f ) can be chosen.
MAX
202 Output frequency high limit (FMAX)
(OUT FREQ HI LIM)
Value:
f - 132
MIN
Function:
In this parameter, a maximum motor frequency can be
selected that corresponds to the highest frequency at
which the motor is to run. The factory setting is 60
Hz for AKD 5001-5062 380-500 V, AKD 5001-5062
550-600 V and 5001-5027 200-240 V.
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.
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 always active in Process
control, closed loop (parameter 100).

Description of choice:
Set the desired value.
The unit follows the choice of configuration
in parameter 100.

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
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 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.

Process control, closed loop:
Special motor characteristics, activated in parameter
101, use the unit selected in parameter 100.
207 Ramp-up time 1
(RAMP UP TIME 1)
Value:
