Sequence Builder
A sequence is a function that performs a specific action, such
as changing the AC output voltage, frequency, or waveform, or
outputting a trigger signal, at a predetermined point in time
(step). T h e PCR-LA Ser i e s syste m is provided wi t h a
sequence function. To enable the PCR-LA Series system to
use a sequence, however, change points (steps) must be
specified/ edited and then transferred to th e system to be
controlled . Seq u e n c e Bui l d e r doe s this for you. T his
application has several useful functions including sequence
wizards that automatically generate test data based on entered
parameters and a function for printing out sequence data.
Basically, the sequence wizard performs simulations based
on specified sequence steps. For simulations involving an
instantaneous power failure, voltage fluctuation, or abrupt
phase shift in the single-phase output, however, all you need
to do is enter the relevant para meters, a fter wh ich the
sequence wizard automatically creates the ideal sequence
for the test.
Any or all of the following items can be set for each step. Up
to 100 steps can be specified.
Step items to be edited
Time ....................................... Set the duration of the step.
• S e tt ing rang e 0.0 01 s ec ond s to 999 hou rs 5 9
seconds 59.999 seconds
•
Minimum increment 0.001 seconds (resolution: 1 ms)
Voltage ................................... Set the voltage (Vrms) to be output in the step. This
voltage setting is held until the next step begins.
• Setting range 0.0 to 305.0 Vrms
• Minimum increment 0.1 Vrms
* For a three-phase output, set a phase voltage. The
voltage is changed simultaneously with respect to the
time axis.
Voltage ramp .........................Set this item when you want the [Voltage] specified in
the previous step to gradually change to the [Voltage]
specified in this step, over the specified [Time].
Frequency .............................. Set the frequency (Hz) to be output in this step. This
frequency setting is held until the next step begins.
• Setting range 1.00 to 999.9 Hz
• M ini mum in c re men t 1. 00 to 99. 99 H z (se tti ng
resolution: 0.01)
100.0 to 999.0 Hz (setting resolution: 0.1)
* For a three-phase output, the frequency is changed
simultaneously with respect to the time axis.
Frequency ramp ..................... Set this item when you want the [Frequency] specified
in th e p r ev iou s s t e p to gra d ua lly cha n ge to the
[Frequenc y] specified in thi s step, over the spec ified
[Time].
Wave bank ............................. From the Wave Bank Server, select the waveform to be
used in this step.
• Setting range No. 0 to No. 13
No. 0 is dedicated to a sine waveform, while Nos. 1 to
13 are the Wave Bank Server’s current wavefor ms.
Output .................................... Indicates whether to supply power.
Trigger ................................... Set this item when you want to output a trigger signal
from the BNC co nnect or on th e ba ck pan el of th e
PCR- LA Serie s sys tem when this step is execute d.
This signal can be used as a trigger for an oscilloscope
or the like.
Waveform synchronization .... Set this item when you want this step to be executed
after the next zero crossing of the output voltage.
Software Quick Wave Sequencer SD04-PCR-L(E)
Implements highly flexible simulation test environments through the use of a waveform bank and the
sequence operation functions of the PCR-LA Series.
Arbitrary waveform creation software Quick Wave Sequencer [model name: SD04-PCR-L(E)] allows you to perform AC power line simulations by exploiting the
functions of the PCR-LA Series system. This lets you create any desired power conditions, including abnormal power feed statuses that rarely occur with general
commercial power lines, and ideal power feed statuses.

(featuring a three-phase output driver).
Supports the se tti ng of individual in ter-w ire phase
differences for a three-phase system
With a three-phase system, differences can be set between
individual phases, and sequence control (for changing the
voltage and frequency, etc.) can be exerted over either all
the phases or one of the three phases (U, V, or W).
Easy reproduction of simulation tests
The created test data can be saved as a configuration file,
making it easy to perfor m the same test again at a later
date. It is also possible to transfer the configuration file via
e-mail or a commercial BBS and reproduce the same test
on a PCR-LA Series system at a remote location.
Test summary print-out
A summary of the created test data can be printed out for
checking.
Software Operation Concept
Quick Wave Sequencer [model name: SD04-PCR-L(E)]
consists of two applications - Sequence Builder and Wave
Bank Server - which run in conjunction with each other.
