8-2. Current Position Value Setting Data (Master to Remote Station)
The master station can change the position data of VE-2CC/VM-2CC at arbitrary values by using the remote
register (RWw) and remote output (RY). (Current position value setting)
After setting, the remote station sends back the answer back signals by using remote inputs (RX). The master
station turns off the signal after checking the bit.
The information of setting position data is saved in non-volatile memory which is inside of the converter;
therefore, it is unnecessary that the current position value sets each time to turn ON the power
supply.

[Signal explanation]
Signal name Name Contents
PRD0-23
Current position value
setting data
The position data can be changed to an arbitrary value by
switching “PRESET” signal to “1”. (binary code: PRD0-23)
(The data except the valid number of bits is fixed at 0.)*1

PRESET
ANSWER
Answer back
The value is 1 when the current position setting is operated
normally.
“RRESET ANSWER” signal is 0 when “RRESET” is changed to 0.
ERROR
RESET
Error clear
An error is cleared when switching this signal to “1” by following
method.
- Converter diagnosis data error (ME)
(The sensor error is automatically returned when error causes are
removed.)
*1: PRESET (RY08) signal should be turned OFF when the current position data and preset data are same
value.
The position data are changed when PRESET (RY08) signal is switched OFF to ON.
Note
In the state of having a sensor error, the current position setting is not available.
