6.3 Additional setting-up
Refer as required to the following sections later in this chapter:
• De-rating the Drive
• Calibrating the analog input
• Specifying a different initially displayed parameter
• Using the programmable parameter to indicate rate of flow
If required, refer also to the following:
• Appendix D Optimising the Dynamic Performance on page 93
• Appendix H Storage and Transfer of Parameter Values on page 108
(cloning)
6.4 De-rating the Drive
Follow this procedure if the output current of the Drive is to be de-rated;
this should have been established when the Installation Guide was being
followed.
1. Set
4.07 Symmetrical current limit Kc1 at the required percentage of
the rated output current of the Drive. The value will define the 2-
second overload current.
2. If gain sequencing is to be used (see Appendix D Optimising the
Dynamic Performance on page 93), repeat the previous step for the
following parameters:
4.24 Symmetrical current limit Kc2
4.28 Symmetrical current limit Kc3
3. Perform the following, as appropriate:
Version _AN
Initiate the save operation by setting parameter XX.00 at 1000.
Execute the operation by performing either of the following:
• While the display is in Edit mode, press at the same time:
•Setparameter
10.38 at 100 (via serial communications)
Version _SL
Version _AN
(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 thestore 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.
4. Version _
AN:Sothatthesaved values are used after the next
power-up, ensure parameter
0.50 is set at no (0).Ifyouhaveto
change the setting, immediately afterwards execute the operation,
as described in step 3.
5. Version _
SL:Sothatthestored valuesareusedafterthenext
power-up, ensure parameter
0.50 is set at 4 (boot2).Ifyouhaveto
change the setting, immediately afterwards execute the operation,
as described in step 3.
6.5 Calibrating the analog input
When the speed is being controlled by an analog speed reference, the
analog input that is in use (high- or standard-precision, depending on
Drive version) can be automatically calibrated for the actual voltage
range of the speed reference.
Procedure
1. Ensure the Hardware enable contact is open.
2. If not already performed, follow the instructions in Unlocking
Standard Security on page 42.
3. Version _
AN: Check the lower line of the alphanumeric display
states
inh.
Version _
SL: Check that the value of parameter 0.01 is 0.
4. Apply the required speed-reference voltage (not exceeding ±10V)
for maximum speed, as follows:
Version _
AN: STANDALONE connector, pins 13 and 12
Version _
SL: SIM EMC connector, pins 4 and 3
5. Set parameter
7.25 Calibrate analog input 1 full scale at 1.
6. The scale factor is automatically entered in parameter
7.53V/f scale.
7.25 automatically returns to 0.
7. Perform the following, as appropriate:
Version _AN
Initiate the save operation by setting parameter XX.00 at 1000.
Execute the operation by performing either of the following:
• While the display is in Edit mode, press at the same time:
•Setparameter
10.38 at 100 (via serial communications)
Version _SL
Version _AN
(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 thestore 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.
8. Version _
AN: So that the saved valuesareusedafterthenext
power-up, ensure parameter
0.50 is set at no (0).Ifyouhaveto
change the setting, immediately afterwards execute the operation,
as described in step 3.
9. Version _
SL:Sothatthestored values are used after the next
power-up, ensure parameter
0.50 is set at 4 (boot2).Ifyouhaveto
change the setting, immediately afterwards execute the operation,
as described in step 3.
This procedure can be repeated, as required.
6.6 Analog input scaling
To adjust the full scale speed with a higher resolution, a scaling factor
needs to be introduced. This is possible by using the following
parameters:
7.55 Analog input scaling numerator
7.56 Analog input scaling denominator
7.57 Analog input scaling enable
To increase the resolution, ensure that large numbers are selected for
the numerator and denominator.
Ensure the motor shaft is disconnected for the
following two procedures. This will allow the motor to
run without the limitation of end stop or mechanical
limitations.
Procedure
Example:
Full scale analog input = 9.0V
Full scale speed = 3000rpm
1. Enable analog input scaling by setting parameter
7.57 to 1
2. ThescalingfactorrequiredtooperatetheDrivefroma9Vanalog
input for 3000rpm:
3. Enable the Drive and set controller to full scale speed. Check the
motor makes the required speed. If the speed is not quite reaching
the required full scale speed, make minor changes to the scaling
factor.
4. Perform the following, as appropriate:
Version _AN
Initiate the save operation by setting parameter XX.00 at 1000.
Execute the operation by performing either of the following:
• While the display is in Edit mode, press at the same time:
•Setparameter
