3-02 Minimum Reference
Range: Function:
Application
dependent*
[Application dependant] Enter the Minimum Reference. The Minimum Reference is the lowest value obtainable by summing
all references. The Minimum Reference value and unit matches the configuration choice made in
par. 1-00
Configuration Mode
and par. 20-12
Reference/Feedback Unit
, respectively.
NB!
This parameter is used in open loop only.
3-03 Maximum Reference
Range: Function:
Application
dependent*
[Application dependant] Enter the maximum acceptable value for the remote reference. The Maximum Reference value and
unit matches the configuration choice made in par. 1-00
Configuration Mode
and par. 20-12
Ref-
erence/Feedback Unit
, respectively.
NB!
If operating with par. 1-00
Configuration Mode
set for Closed Loop [3],
par. 20-14
Maximum Reference/Feedb.
must be used.
3-10 Preset Reference
Array [8]
Range: Function:
0.00 %* [-100.00 - 100.00 %] Enter up to eight different preset references (0-7) in this parameter, using array programming. The
preset reference is stated as a percentage of the value Ref
MAX
(par. 3-03
Maximum Reference
, for
closed loop see par. 20-14
Maximum Reference/Feedb.
). When using preset references, select Pre-
set ref. bit 0 / 1 / 2 [16], [17] or [18] for the corresponding digital inputs in parameter group 5-1*
Digital Inputs.
3-15 Reference 1 Source
Option: Function:
Select the reference input to be used for the first reference signal. Par. 3-15
Reference 1 Source
,
par. 3-16
Reference 2 Source
and par. 3-17
Reference 3 Source
define up to three different refer-
ence signals. The sum of these reference signals defines the actual reference.
This parameter cannot be adjusted while the motor is running.
