4.2.8 Modified Constants Mode
The modified constants mode is used to change or display user constants that have been changed from their
factory-preset values.
When any user constants have been changed in programming mode (b1-01 through o2-08), press the
DATA/ENTER Key in modified constants mode to display these user constants. (The initialize mode user
constants won’t be displayed.)
Changing Frequency Reference 1 to 30.00 in Modified Constants Mode
In the following example, user constants C1-01 (Acceleration time 1) and d1-01 (Frequency reference 1)
have been changed from their factory settings.
The settings for these two user constants are displayed, and the setting for d1-01 is changed from 60.00 Hz
to 30.00 Hz while C1-01 is set to 20.0 seconds.
