(REFERENCE SITE)
Value:
★ Hand/Auto linked reference
(LINKED TO HAND/AUTO)) [0]
Remote reference (REMOTE) [1]
Local reference (LOCAL) [2]
Function:
This parameter decides which resulting reference is to
be active. If Hand/Auto linked reference [0] is selected,
the resulting reference will depend on whether the
VLT 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 chosen, 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 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.
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
MIN
- 1000.000 Hz ✭ 50.000 Hz
Parameter 100 Configuration = Closed loop [1]
Par. 204 Ref
MIN
- par. 414 Maximum feedback ✭ 50.000 Hz
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).
