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 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:
-Par. 413 Minimum feedback
- par. 205 Ref
MAX
✭ 0.000
Function:
The Minimum reference gives the minimum
value that can be assumed b
ythesumofall
references. The minimum reference is limited by
parameter 413 Minimum feedback.
Minimum reference is ign
ored when the local reference
is active (parameter 203 Reference site). The unit
for the reference is set in 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:
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.
The maximum reference cannot be set above
parameter 414 Maximum feedback .TheMaximum
reference is ignored when the local reference is
active (parameter 203 Reference site ).
The reference unit is set in 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.
206 Ramp-up time
(RAMPUPTIME)
Value:
1 - 60 sec.
✭ Depends on the unit
Function:
The ramp-up time is the acceleration time from 0
Hz to the rated motor frequency f
M,N
(parameter
104 Motor frequency, f
M,N
). It is assumed that the
output current does not reach the current limit (set
in parameter 215 Current limit I
LIM
).
Description of choice:
Program the desired ramp-up time.
