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):
•
FINDEL (1):
•
•
INIFIN (2):
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.
