Analog-input selection
When parameter 1.14 is set at 0, 1 or 2, parameter 7.10 is automatically set at 1.36 in order to select parameter 1.36 as the destination
parameter for the analog input. The setting of 7.10 cannot then be changed.
Other settings of parameter 1.14 allow parameter 7.10 to be set at any value (including 1.36).
When parameter 7.10 issetatanyofthefollowing...
1.36
(irrespective of the setting of parameter 1.14)
4.08
3.22
... the parameters listed below are by-passed in order to simplify setting-up and increase speed of response to changes in the input signal:
7.01 Analog input
7.07 Analog input offset trim
7.08 Analog input scaling
7.09 Analog input invert
Parameter 7.54:sampletime=250µs
Pulse Mode
The analog input destination selector parameter 7.10 cannot be used when a Pulse reference is selected (i.e parameter 1.14 to 5).
This is due to the internal characteristics of the drive.
Analog-input scaling
Analog-input scaling operates only when 7.10 Analog input destination selector is set at 1.36 or 3.22 and 7.57 Analog input scaling enable is
set at 1.
The scaling should be used for final adjustment only. Keep the ratio of 7.55 over 7.56 below 1.1. Failure to do so will
possibly end up in speed reversal
The appropriate parameter, as follows, indicates the scaled speed demand:
1.36 Analog reference
3.22 Hard speed reference
