Table 4-1.
The parameters of a step program.
Choosing gradient ( ), means that a
voltage endpoint
for the actual phase is
programmed together with
current and power limiting values
. A linear voltage
gradient is made with zero (for the first phase) or the programmed endpoint of the
phase before (for the next phases) as starting point and the programmed endpoint as
No.
