Option board OPTD7 (Line voltage measurement board)
OPTD7 is an AC sinusoidal voltage measurement board. Using this board, the drive measures the
line voltage, frequency and voltage angle information. The drive can compare this information with
its output voltage angle when running. This feature can be used to develop applications for different
purposes using NC61131-3 application programming tool.
The OPTD7 board is delivered with the transformer which is suitable for voltage range 380V …690V.
Please note that the transformer can not be used with the pulse width modulated (PWM) voltage in-
put.
It is possible to use custom built transformer when the input voltage to be measured is not within
the above voltage range. The transformation ratio parameter then can be adjusted as per the trans-
former primary to secondary ratio. Please refer to specification section for further engineering.
The measurement signal connected into the OPT-D7 option board can not exceed 14.26 Vrms.
The board can only be placed in slot C.
