Supplementary publications and manuals are available from Danfoss. 1.3 Disposal Do not dispose of equipment containing electrical components together with domestic waste. Collect it separately in accordance with local and currently valid legislation. 4 | Danfoss A/S © 2023.03 AQ442338036238en-000201 / UD01056 Line Voltage Measurement Operating Guide Product Overview 2 Product Overview 2.1 Intended Use OPTD7 is an AC sinusoidal voltage measurement option board used in VACON® NXP drives. VACON® NXP drive measures the line voltage, frequency and voltage angle information using this board. VACON® NXP can compare this information with its output voltage angle when it is running. This feature can be used to develop applications for different purposes using NC61131-3 application programming tool. e30bk631.10 21 22 23 Illustration 1: OPTD7 Option Board Layout The OPTD7 option board is delivered with the transformer which is suitable for voltage range 380-690 V. e30bk630.10 Illustration 2: Transformer NOTE! The transformer can not be used with the pulse width modulated (PWM) voltage input. It is possible to use custom built transformer when the input voltage to be measured is not within the voltage range 380-690 V. The transformation ratio parameter can be adjusted as per the transformer primary to secondary ratio. Please refer to specification section for more information. NOTICE The measurement signal connected into the OPTD7 option board can not exceed 14.26 Vrms. The OPTD7 option board can only be used in slot C of VACON® NXP drive.
