Changing Parameter Settings or Values
This example explains changing C1-02 (Deceleration Time 1) from 10.0 seconds (default) to 20.0 seconds.
Note: During serial communication writing, if a parameter change is also attempted via the HOA keypad, a “BUSY - WRITE PROTECTED”
message will display. Parameter change will not be possible from the HOA keypad until an Enter command is received via the serial
communication to finish the serial writing process.
