[2] Analog input 54
Function:
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
Configuration Mode and par. 20-12 Reference/Feedback Unit , respectively.
par. 1-00
NB!
This parameter is used in open loop only.
Function:
Enter the maximum acceptable value for the remote reference. The Maximum Reference value and
unit matches the configuration choice made in par. 1-00
erence/Feedback Unit , respectively.
NB!
If operating with par. 1-00
par. 20-14 Maximum Reference/Feedb. must be used.
Function:
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
Maximum Reference/Feedb. ). When using preset references, select Pre-
closed loop see par. 20-14
set ref. bit 0 / 1 / 2 [16], [17] or [18] for the corresponding digital inputs in parameter group 5-1*
Digital Inputs.
Function:
Select the reference input to be used for the first reference signal. Par. 3-15
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.
