1. Introduction
VF-S15 has trace function to retain the data at tripping and at triggering and to read out such
data until resetting the tripped inverter or turning off the power.
Up to 4 types of data can be selected from approximately 25, and 100 consecutive points can
be stored as trace data, which is useful for determining the cause.
RS485 communication and the software for trace function, PCT002Z-E, are used for VF-S15.
Use PC to read data.
*1: Please contact your Toshiba distributor for the software:PCT002Z-E.
*2: USB converters unit (optional), USB cable (optional,A-B connection type), and
commercially available USB cable are necessary to connect to the PC.
Refer to the Trace tool PCT002Z-E Instruction Manual (E6581857) for usage and connection.
PCT002Z-E cannot be used for trace function of VF-AS1 and VF-PS1.

2. Trace function
VF-S15 retains the data collected at the time of tripping or triggering and reads out such data
until resetting the tripped inverter or turning off the power.
Up to 4 types of data can be selected from approximately 25, and 100 consecutive points can
be stored as trace data.
As the data including change of current at tripping can be read out, these trace data is useful
for determining the cause of trip and triggering.
Here is the time at which trace data is acquired.
Tripping : Data collected before the trip occurs
Triggering: Data collected after triggering
Use RS485 communication and the software for trace function, PCT002Z-E.
Use PC to read data.

Setting value 77 is reverse signal.
Note 1:If the inverter trips when no trigger signal is given, trace data is overwritten with
tripping data.
Note 2:Trace data is overwritten each time a trigger signal is given.
Note 3:When retry operation is occurred, the data at first tripping is written. The trace data is
cleared at retry success.

2.2 Acquisition of trace data
2.2.1 Example of acquisition of trace data
1) To acquire trace data until the occurrence of tripping: f740=1, 3
(Examples of current date output)
* In case of trigger input when setting f740=3, operation is that described in 3).
2) To acquire trace data at the time of triggering: f740=2
3) To acquire trace data until the time of triggering: f740=3
* In case of tripping when setting f740=3, operation is that described in 1).

Relationship between pointer and data
The table below shows the relationship between pointer (E000 set value) and trace
data (1 to 4).
Pointer (E000 set value) 012- 9899
Trace data 1（E100 to E199）E100 E101 E102 - E198 E199
Trace data 2（E200 to E299）E200 E201 E202 - E298 E299
Trace data 3（E300 to E399）E300 E301 E302 - E398 E399
Trace data 4（E400 to E499）E400 E401 E402 - E498 E499
<Example of setting> If E000 is set to 2:
(Earliest data) (Latest data)
Trace data 1 E102 to E199, E100, E101
Trace data 2 E202 to E299, E200, E201
Trace data 3 E302 to E399, E300, E301
Trace data 4 E402 to E499, E400, E401
Note 1: Use the parameters f742 through to f745 to specify the types of trace
data (1 to 4).
Note 2: Communication numbers E000 is automatically incremented by the inverter
when data is traced continuously.
* In ordinary cases, these parameters do not need to be rewritten.
