6.7.8 STEP or RAMP Parameters
Step transients can be used to create discrete stair step like voltage and/or frequency
changes or smooth ramps. The default ramp time is 0.1 msec.
Ramps can be can be programmed in three modes:
• INIDEL (0): Initial & Delta: Programmed by initial and delta values
•
FINDEL (1): Final & Delta: Programmed by final and delta values
•
INIFIN (2): Initial & Final: Programmed by initial and final values
Step transients can be used to step frequency, AC voltage and phases.
The HOLD is ON, the last step values will be set as steady-state when the step execution
ends. Duration of each step is determined by: LENGTH = WIDTH + RAMP TIME
The following parameters are available in a STEP VALUES screen.
