References & Limits
201 Output frequency low limit, f
MIN
(MIN OUTPUT FREQ)
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
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
(MAX. OUTPUT FREQUENCY)
Value:
f
MIN
- 132 Hz
✭
60.0 Hz
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
MIN
to 132 Hz.

MAX
✭
0.000 bar/par 416
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:
Par. 100
Configuration
Unit
Open loop [0]
Hz
Process reg, closed loop [1]
Par. 416
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

Value:
Par. 100

Max. feedback
✭
32.000 bar/par 416
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
Unit
Open loop [0]
Hz
Process reg, closed loop [1]
Par. 416
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
✭
0.70 sec
Function:
The ramp-up time is the acceleration time from 0
Hz to the rated motor frequency f
