(if required)
Ensure the Drive is disabled by checking that the Hardware enable
contact is open or that parameter 6.15 is set at 0 , then perform either
of the following:
•
Initiate the store operation by setting parameter 0.50 at 2 ( Prog ).
Execute the operation by setting parameter 10.38 at 100 .
• Set 11.67 Flash update enable at 1 .
6.7 Specifying a different initially
displayed parameter
Version _ AN
1. If the value of an advanced parameter is to be displayed, set 0.35
User security code at 0 .
2. Set 0.38 Initial parameter displayed selector at the number of the
required parameter.
3. Initiate the save operation by setting parameter XX.00 at 1000 .
4. Execute the operation by performing either of the following:
•
While the display is in Edit mode, press at the same time:
• Set parameter 10.38 at 100 (via serial communications)
5. To use the saved values used after the next power-up, ensure
parameter
0.50 is set at no ( 0 ). If you have to change the setting,
immediately afterwards execute the operation, as described in step
4.
6. The value of the specified parameter is now displayed and will be
displayed every time the Drive is subsequently powered-up.
6.8 Setting up the programmable
parameter
Versions_AN,_SL
Parameter [ 0.46 ] can be assigned to any advanced parameter and given
a scaling factor. Typical uses are as follows:
•
Indicates the rate of flow in a way that is meaningful to the produc-
tion process (e.g cans per hour)
• Indicates the torque calculated from the motor current.
The default function is as follows:
0.1 x [
0.05
] speed feedback
1. Assigning [0.46] to another parameter.
Enter the number of the required parameter in [ 11.20 Parameter
0.46 assigned selector].
2. Changing the scaling for [0.46.]
Note the number of decimal places used by the values of the
parameter assigned to parameter [0.46]. Obtain the value of the
modifier from the following table.
3. Use [
11.21
] to define the required scaling factor, as follows:
[ 11.21 ] = [ 0.46 ] / [ XX.XX ] x M
Where:
[ XX.XX ] is the value of the parameter that is assigned to parameter
0.46 by parameter [ 11.20 ].
4. Perform the following, as appropriate:

5. Version _
AN
: So that the saved values are used after the next
power-up, ensure parameter 0.50 is set at no ( 0 ). If you have to
change the setting, immediately afterwards execute the operation,
as described in step 3.
6. Version _ SL : So that the stored values are used after the next
power-up, ensure parameter 0.50 is set at 4 ( boot2 ). If you have to
change the setting, immediately afterwards execute the operation,
as described in step 3.
This procedure can be repeated, as required.
Examples
Default settings.
Parameter assigned to parameter [ 0.46 ] = [ 3.02 ]
Number of decimal places used in the value of parameter [ 3.02 ] = 1
Therefore M = 1
Default setting of parameter [ 11.21 ] = 0.1
The value of parameter [ 0.46 ] is given by:-
[ 0.46 ] = [ 3.02 ] x [ 11.21 ] x M
For example, when [ 3.02 ] = 1500rpm, [ 0.46 ] is as follows:-
[ 0.46 ] = 1500 x 0.1 x 1 = 150
Approximate indication of torque.
1. Set parameter [
11.20
] at [
4.01
] or [
0.07
] (motor current magnitude).
2. Two decimal places are used in the value, therefore M = 10
3. Set parameter [ 11.21 ] at 0.16 (1.6 / 10 = 0.16) to represent the K
T
of
the motor. (Here K
T
is divided by 10 due to M = 10.)
4. Parameter [ 0.46 ] will indicate as follows:-
[ 0.46 ] = [ 4.01 ] x 0.16 x 10
When [ 4.01 ] is 2.75A:-
[ 0.46 ] = 2.75 x 0.16 x 10 = 4.4
