Actual signals and parameters
Description
Scales the analogue output AO1 signal.
Scaling factor. If the value is 100%, the reference value of the drive signal
corresponds to 20 mA.
Example: The nominal motor current is 7.5 A and the measured maximum
current at maximum load 5 A. The motor current 0 to 5 A needs to be read as 0
to 20 mA analogue signal through AO1. The required settings are:
1. AO1 is set to CURRENT with parameter 15.01.
2. AO1 minimum is set to 0 mA with parameter 15.03.
3. The measured maximum motor current is scaled to correspond to 20 mA
analogue output signal by setting the scaling factor (k) to 150%. The value is
defined as follows: The reference value of the output signal CURRENT is the
motor nominal current, that is 7.5 A (see parameter
the measured maximum motor current correspond to 20 mA, it should be
scaled equal to the reference value before it is converted to an analogue
output signal. Equation:
k × 5 A = 7.5 A => k = 1.5 = 150%
Defines the source or constant for value.
Parameter index or a constant value. See parameter
for information on the difference.
For example, default value 001.005 (signal 01.05) is used for actual torque.

Run Enable, parameter lock etc.
Sets the Run Enable signal on, or selects a source for the external Run Enable
signal. If Run Enable signal is switched off, the drive does not start or stops if it
is running. The stop mode is set with parameter
After the drive stops on Run disable condition, the drive does not restart
automatically if the run enable signal is switched on with the Start command is
ON. A new Start command has to be given for a new start.
Run Enable signal is on.
External signal required through the Fieldbus Control Word (bit 3).
Digital input DI7 is the signal source.
Digital input DI9 is the signal source.
Digital input DI11 is the signal source.
