Parameters — References and limits
201 Output frequency low limit (F
MIN
)
(OUT FREQ LOW LIM)
Value:
0.0 - f
MAX
✭
30.0 Hz
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
MAX
.
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
MAX
) can be chosen.
202 Output frequency high limit (FMAX)
(OUT FREQ HI LIM)
Value:
f
MIN
- 132
✭
60 Hz
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
✭
30.0 Hz
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.
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
✭
60.0 Hz
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.
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.
207 Ramp-up time 1
(RAMP UP TIME 1)
Value:
0.05 - 3600 sec.
✭
0.7 sec
Function:
The ramp-up time is the acceleration time from 0 Hz
to the rated motor frequency f
M,N
