Overview of Sequence Creation
A sequence is a feature that automatically executes the predefined steps in a given order. By combining separate steps into a sequence, you can simulate various waveforms.

A sequence comprises multiple steps, which will be executed in a given order. A single sequencecan comprise up to 1024 steps. The execution of the last step normally concludes the sequence. If
you set the repetition count of a sequence, however, the sequence will be repeatedly executed until
it reaches to the last count.

Sequence execution procedure

1 Set the operating conditions for the sequence.
2 Set the operating conditions for the steps.
3 Execute the sequence.

When the maximum time is set to be automatically scaled
When the [Auto] check box of [Max time] is selected, you can specify either [Roll mode] or [Normalmode].

 Roll mode
The X-axis and Y-axis are simultaneously scaled. The display range is defined by subtracting theminimum time setting from the maximum time setting.

 Normal mode
In normal mode, the minimum time is fixed to a given value whereas the maximum time isscaled.
When the [Scrolling within the specified range] check box is selected, the graph is scaled whenthe monitored value exceeds the maximum time on the X-axis. In this case, the time range to be
scrolled is defined by subtracting the minimum time setting and the scrolling time from the
maximum time setting.
For example, if the minimum time is set to 0 s, the maximum time is set to 23 s, and the scroll
time is set to 10 seconds, the time range will be 13 s (calculated from 23-0-10).

About Operating Modes
The PWX Series functions as a constant-voltage source or a constant-current source. In constantvoltage (CV) mode, the PWX Series holds the output voltage to a certain value regardless of theload change. Whereas in constant-current (CC) mode, the PWX Series holds the output current to acertain value regardless of the load change. These operating modes are determined by the following three factors.
Output voltage setting (Vs)
Output current setting (Is)Load resistance (RL)
The figure below explains the operating modes.

The load resistance is denoted as “RL”. The resistance, which is calculated from the voltage and current settings (RC=Vs/Is), is denoted as “Rc”. The PWX Series is designed to function in CV mode
within A range, and function in CC mode within B range. A and B are divided by the “RL=Rc” boundary line. On this boundary line, the output voltage equals the voltage setting, and the output current equals the current setting. When the load resistance RL is greater than the resistance Rc, thePWX Series operates in CV mode as the operating point (p point) lies within A range. In this case, thecurrent setting (Is) equals the current limit.
While the PWX Series is operating in CV mode, the output voltage is hold to a certain level. Output
current “I”, on the other hand, is determined by the equation I=Vs/RL and is lower than the current
limit “Is”. The flowing current may not equal the current setting.
For the loads in which transient peak current flows, the current limit “Is” needs to be set higher thanthe peak value.
In contrast, when the load resistance RL is lower than the resistance Rc, the PWX Series operates in
CC mode as the operating point (q point) lies within B range. In this case, the voltage setting (Vs)equals the voltage limit.
While the PWX Series is operating in CC mode, the output current is hold to a certain level. Output
voltage “V”, on the other hand, is determined by the equation V=Is/RL and is lower than the current
limit “Vs”. The flowing voltage may not equal the voltage setting.
For the loads which causes the transient voltage surge, the voltage limit “Vs” needs to be set higher
than the voltage surge.

Crossover point
The operating modes (CV or CC) automatically switches due to the changes in the load. A crossover
point is referred to as the point where the operating mode switches.
For example, if the load changes and the output current reaches to its limit while in CV mode, thePWX Series switches to operate in CC mode for protecting the load. Likewise, if the output voltage
reaches its limit while in CC mode, the PWX Series switches to operate in CV mode.

About Operating Modes

CV/CC modes operation example
The following cases take the PWX Series with rated output voltage 100 V and rated output current
10 A as examples.
First, assume that 8 Ω load resistance (RL) is connected to the output terminals of the PWX Series,
and the output voltage and output current are set to 30 V and 5 A respectively. In this case, the PWX
Series operates in CV mode because RL (8 Ω) is greater than Rc (Rc=30 V/5 A=6 Ω). You can still raisethe voltage up to 40 V (calculated from Vs = ls x RL, that is, Vs = 5 A x 8 Ω = 40 V) in CV mode. If you
attempt to raise the voltage any further, however, the voltage reaches to the crossover point and
the PWX Series automatically switches to operate in CC mode. To allow the PWX Series to continue
operating in CV mode, raise the current limit.
Next, assume that 5 Ω load resistance (RL) is connected to the output terminals of the PWX Series,
and the output voltage and output current are set to 30 V and 5 A respectively. In this case, the PWX
Series operates in CC mode because RL (5 Ω) is lower than Rc (Rc=30 V/5 A=6 Ω). You can still raise
the current up to 6 A (calculated from Is=Vs/RL, that is, Is=30 V/5 Ω=6 A) in CC mode. If you attempt
to raise the current any further, however, the current reaches to the crossover point and the PWX
Series automatically switches to operate in CV mode. To allow the PWX Series to continue operatingin CC mode, raise the voltage limit.
