4-2 Function Mode FREQ adjuster Frequency reference source A001 Terminal block Σ + Output frequency setting F001 set value ModBus communication Logic operation output +/– A145 Frequency addition Frequency addition direction setting A146 Multi-function input [ADD] Forced Terminal Block Function 4 This function forcibly switches to operation via the terminal block by turning on/off the multi-function terminal when the frequency reference/RUN command sources are not set to the terminal block. Functions •When the input of this signal is reset, A001 and A002 return to the command status prior to the input.
•If you switch on/off this function during operation, the RUN command is reset to stop the Inverter. Before resuming operation, stop the RUN command from each command source to avoid possible danger and then input it again. Ready Function •Inputting this signal shortens the time between the RUN command input and the start of actual operation. In normal status, this is approx. 20 ms. Shortened time through this function varies depending on timing. When the Inverter is in ready status, high voltage is applied to terminals U, V, and W on the main circuit terminal block. This happens even if the motor is stopped with the RUN command turned off. Do not touch the main circuit terminal block.
