please do not use a PLCH function (i-01=0). RWr1 and 4 will become an unfixed value if a PLCH function is used.

3.6 Monitor code specification
CC66-Z differs in the composition of a monitor code by use of a built-in PLC function (PLCH), or un-using it. A
setup for use of a built-in PLC function or un-using it is set up with the setting parameter (i area) of a VF66B
inverter, as shown in Table 3.8. In detail, refer to VF66B inverter instructions manual. The description of VF66
PCTool is referred to for a built-in PLC function.
The details of the monitor code in the case of not using PLCH function are shown in Table 3.9. The detailsof the monitor code in the case of using PLCH function are shown in Table 3.10. Set a monitor code in the
remote register RWw suitable in a master station.
When the value of i-01 is changed, please re-switch on the power supply of an inverter.
If the monitor code of contents to monitor is written in the corresponding remote register RWw withreference to Table 3.9 or 3.10 and the remote input RYC is turned on, the information corresponding to thecontents of the code No. will be transmitted to a master station from a slave station.

In the case of V/f mode, the frequecy minimum unit of code No.0x0001 is set to 0.1Hz when the highest
frequency (A-00) is 300Hz or more, and in the case of below it, it is set to 0.01Hz. In the case of IM vector
mode and ED vector mode, the setting minimum unit of Code No.0X0001 is set to 0.1Hz when the frequency
which is converted from pole numbers (A-06) and highest rotarion speed (A-00) set as the inverter, is 300Hz
or more, and in the case below it, it is set to 0.01Hz.
Moreover, in the case of the inverter capacity of 45kW or more in 200V system and 110kW or more in 400V
system, the current monitor minimum unit of code No.0x0002 is set to 0.1A. in the case of inverter capacity
is except the above, the current monitor minimum unit is set to 0.01A.
For example, the minimum unit of a current monitor is set as 0.1A, and when inverter output current is

The protection history data read by protection history read-out of the instruction code 0x1010 is shown. If
RYF is turned on after it sets the instruction code 0x1010 to RWw2 and the protection data to read inputs into
"write-in data" (RWw3) the number which shows the what position past it is, the protection code shown in
Table 3.23 is set to "reading data" (RWr3), and it is transmitted to a master station.
For example, when the protection history data which set 0 to "write-in data" and was read to it is
0x0001, it turns out in the newest protection "inverter mode is V/f mode and the inverter protection
operated by over-current protection using the first setting block."

３．７．３ Trace-Back Data Read-out
VF66B inverter memorizes the data of the current at the time of protected operation, voltage, etc., andcontains the trace back function which reads afterwards and is used for analysis. In order to use a trace backfunction effectively, it is necessary to set a setting parameter (F area) correctly in the main part of an inverter
beforehand. For details, refer to the instructions manual of the main part of VF66 inverter.
The following procedures perform read-out of the trace back data of VF66B inverter.
The instruction code 0x1020 is set to RWw2. The contents of "write-in data" (RWw3) are as follows.
Table 3.24 The contents of write-in data at the time of a Trace-Back Data demandSpecification bit
0 to 7 bit
8 to 11 bit
12 to 15 bitContents
The sample point of the trace back data to 0 to 99 is specified.
0 to 15 channels of trace back data are specified.
The storing block of trace back data is specified. The VF66B inverter saves
the past 4 times of trace back data. If 0 is specified, the newest trace backdata will be required, and if 3 is specified, the oldest trace back data will be
required.

Input range（HEX）
0 to 0x63
0 to 0x0F
0 to 0x03

ON of RYF will require trace back data of VF66B inverter. The data of the specified channel (ch) is stored in"reading data" (RWr3). Furthermore, the trace back data of the channel (ch) of the three point is stored in "thetrace back data 1" (RWrC), the "trace back data 2" (RWrD), and the "trace back data 3" (RWrE).
Example :When the write-in data at the time of a trace back data demand is 0x1120, the data in front of one of thenewest trace back data is required. Since 1 is specified as the trace back data channel, it is the 32nd sample
data of the trace back data of V phase current, W phase current, D.C. voltage, and output voltage from Table
3.25, is stored in "reading data" (RWr3), the "trace back data 1" (RWrC), the "trace back data 2" (RWrD), and the"trace back data 3" (RWrE), respectively.
