6.1.9. Changing Data Value,Step-by-Step
Certain parameters can be changed step-by-step or by an infinite number of variables. This applies
to
Motor Power (par. 1-20), Motor Voltage (par. 1-22) and Motor Frequency (par. 1-23).
The parameters are changed both as a group of numeric data values and as numeric data values
using an infinite number of variables.
6.1.10. Read-out and Programming of Indexed Parameters
Parameters are indexed when placed in a rolling stack.
Par. 15-30 to 15-32 contain a fault log that can be read out. Choose a parameter, press [OK], and
use the up/down navigation keys to scroll through the value log.
Use par. 3-10 as another example:
Choose the parameter, press [OK], and use the up/down navigation keys to scroll through the
indexed values. To change the parameter value, select the indexed value and press [OK]. Change
the value by using the up/down keys. Press [OK] to accept the new setting. Press [Cancel] to
abort. Press [Back] to leave the parameter.
