203 Reference site
(REFERENCE SITE)
Value:
✭Hand/Auto linked reference
(LINKED TO HAND/AUTO)
[0]
Remote reference (REMOTE)
[1]
Local reference (LOCAL)
[2]
Function:
This parameter determines the location of the active
reference. If Hand/Auto linked reference [0] is selected,
the resulting reference will depend on whether the
frequency converter is in Hand or Auto mode.
The table shows which references are active when
Hand/Auto linked reference [0], Remote reference [1] or
Local reference [2] has been selected. The Hand mode
or Auto mode can be selected via the control keys or
via a digital input, parameters 300-307 Digital inputs.
Reference
handling Hand mode Auto mode
Hand/Auto [0] Local ref. active Remote ref. active
Remote [1] Remote ref. active Remote ref. active
Local [2] Local ref. active Local ref. active
Description of choice:
If Hand/Auto linked reference [0] is chose
n, the motor
speed in Hand mode will be decided by the local
reference, while in Auto mode it depends on remote
references and any setpoints selecte
d.
If Remote reference [1] is selected, the motor speed will
depend on remote references, regardless of whether
Hand mode or Auto mode has been cho
sen.
If Local reference [2] is selected, the motor speed
will only depend on the local reference set via the
control panel, regardless of wh
ether Hand mode
or Auto mode has been selected.
204 Minimum reference, Ref
MIN
(MIN. REFERENCE)
Value:
Parameter 100 Configuration = Open loop [0].
0.000 - parameter 205 Ref
MAX
✭ 0.000 Hz
Parameter 100 Configuration = Closed loop [1].
-Par. 413 Minimum feedback
- par. 205 Ref
MAX
✭ 0.000
Function:
The Minimum reference gives the minimum value
that can be assumed by the sum of all references.
If Closed loop has been selected in parameter 100
Configuration, the minimum reference is limited by
parameter 413 Minimum feedback.
Minimum reference is ignored when the local reference
is active (parameter 203 Reference site). The unit for
the reference can be seen from the following table:
Unit
Par. 100 Configuration = Open loop Hz
Par. 100 Configuration = Closed loop Par. 415
Description of choice:
Minimum reference is set if the motor is to run
at a minimum speed, regardless of whether
the resulting reference is 0.
205 Maximum reference, Ref
MAX
(MAX. REFERENCE)
Value:
Parameter 100 Configuration = Open loop [0]
Parameter 204 Ref

- 1000.000 Hz
✭ 60 Hz/50 Hz

) Global factory setting different from North
American factory setting).
Function:
The Maximum reference gives the maximum value
that can be assumed by the sum of all references.
If Closed loop [1] has been selected in parameter
100 Configuration, the maximum reference cannot be
set above parameter 414 Maximum feedback.The
Maximum reference is ignored when the local reference
is active (parameter 203 Reference site).
The reference unit can be determined on the
basis of the following table:
Unit
Par. 100 Configuration = Open loop Hz
Par. 100 Configuration = Closed loop Par. 415
Description of choice:
Maximum reference is set if the motor speed is not
to exceed the set value, regardless of whether the
resulting reference is higher than Maximum reference.
