References & Limits
201 Output frequency low limit, f
(MIN OUTPUT FREQ)
Value:
0.0 - f
MAX
Function:
In this parameter, a minimum motor frequency limit
can be selected that corresponds to the minimum
speed at which the motor is allowed to run.
Description of choice:
The value chosen can range from 0.0 Hz to
the frequency set in parameter 202 Output
frequency high limit, f
MAX
202 Output frequency high limit, f
(MAX. OUTPUT FREQUENCY)
Value:
f - 132 Hz
MIN
Function:
In this parameter, a maximum output frequency limit
can be selected that corresponds to the highest
speed at which the motor is allowed to run.
Description of choice:
A value can be selected from f
204 Minimum reference, Ref
(MIN.REFERENCE)
Value:
Par. 100 Config. = Open loop [0].
0 - par. 205 Ref
MAX
Par. 100 Config. = Closed loop [1].
-Par. 414 Minimum feedback - par. 205 Ref
Function:
Minimum reference is an expression of the minimum
possible value of the total of all references. If in
parameter 100 Configuration or Process regulation,
closed loop [1] is selected, the minimum reference is
limited by parameter 414 Minimum feedback. Minimum
reference is ignored if the local reference is active.
The reference unit can be defined from the
following table:
= factory setting. () = display text [] = value for use in communication via serial communication port

AKD 2800
Par. 100 Configuration
Open loop [0]
Process reg, closed loop [1]
Description of choice:
The minimum reference is preset if the motor
has to run at a minimum speed, regardless of
whether the resulting reference is 0.
205 Maximum reference, Ref
(MAX.REFERENCE)
Value:
Par. 100 Config. = Open loop [0].
Par. 204 Ref - 1000.000 Hz
MIN
Par. 100 Config. = Closed loop [1].
Par. 204 Ref - Par. 415 Max. feedback
MIN
Function:
The maximum reference gives the highest value that
can be assumed by the sum of all references. If Closed
loop [1] is selected in parameter 100 Configuration
the maximum reference cannot exceed the value
in parameter 415 Maximum feedback.
Maximum reference is ignored if the local
reference is active.
The reference unit can be defined from the
following table:
Par. 100 Configuration
Open loop [0]
Process reg, closed loop [1]
Description of choice:
Maximum reference is set, if the speed of the
motor is to be max. the set value, regardless
of the whether the resulting reference is greater
than the maximum reference.
207 Ramp-up time 1
(RAMP-UP TIME 1)
Value:
0.02 - 3600.00 sec
Function:
The ramp-up time is the acceleration time from 0
Hz to the rated motor frequency f
