
When the Input scale high/low parameter is changed
When the high limit or low limit of the input scale is changed, the settings in the following table will be
changed. Reset the settings to the values that you wish to use.
Input scale high (RKC communication identifier: XV, Modbus address: 0182H to 0183H)
Input scale low (RKC communication identifier: XW, Modbus address: 0186H to 0187H)


When the Integral/Derivative time decimal point position parameter is changed
When the Integral/Derivative time decimal point position is changed (RKC communication identifier: PK,
Modbus address: 0236H to 0237H), the decimal point positions of the settings in the following table are
automatically converted. However, in some cases, the change of decimal point position may also change the
set value. Where this occurs, reset the value to the value that you wish to use.
