Table 4-1 and Figure 4-2 illustrate a step program. The programming and running of this
application are shown as Figure 4-1 and Figure 4-5.
Figure 4-2. Programming the voltage limiting profile in STEP mode. The parameters shown are the
same as those listed in Table 4-1.
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
