(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 fre-
quency 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

Description of choice:
If
Hand/Auto linked reference
[0] is chosen, the motor
speed in Hand mode will be decided by the local ref-
erence, while in Auto mode it depends on remote
references and any setpoints selected.
If
Remote reference
[1] is selected, the motor speed will
depend on remote references, regardless of whether
Hand mode or Auto mode has been chosen.
If
Local reference
[2] is selected, the motor speed will
only depend on the local reference set via the control
panel, regardless of whether Hand mode or Auto mode
has been selected.

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
Configura-
tion
, the minimum reference is limited by parameter
413
Minimum feedback
.
Minimum reference is ignored when the local refer-
ence is active (parameter 203
Reference site
). The unit
for the reference can be seen from the following table:

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.

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
Config-
uration
, the maximum reference cannot be set above
parameter 414
Maximum feedback
. The
Maximum ref-
erence
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

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 re-
sulting reference is higher than
Maximum reference
.
