Reference range
(REFERENCE RANGE)
Value:
Min. reference - Max reference (min - max)
[0]
-Max. reference - Max. reference
(-max - +max)
[1]
Function:
In this parameter you select whether the reference
signal must be positive or whether it can be both pos-
itive and negative. The minimum limit may be a nega-
tive value, unless in parameter 100
Configuration
a
selection has been made of
Speed regulation, closed
loop
. You should select
Min ref. - Max. ref.
[0], if
Proc-
ess regulation, closed loop
[3] has been selected in
parameter 100
Configuration
.
Description of choice:
Select the required range.

Function:
Minimum reference is an expression of the minimum
possible value of the total of all references. If in pa-
rameter 100
Configuration
,
Speed regulation, closed
loop
[1] or
Process regulation, closed loop
[3] is selec-
ted, 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
Speed reg, closed loop [1]
rpm
Process reg, closed loop [3]
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.

Function:
The maximum reference gives the highest value that
can be assumed by the sum of all references. If
Closed
loop
[1]/[3] 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]

Process reg, closed loop [3]
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 ref-
erence.

Function:
You can choose between a linear, an S-shaped and
an S

ramp process.
Description of choice:
Select the required ramp type depending on the re-
quired acceleration/deceleration process.
