Functions
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.
Multi-function Output Terminal Selection
•You can allocate the following functions to multi-function output terminal P1 and the relay output
terminals.
•While the multi-function output terminal P1 selection is for open collector output (allocated in
C021), the relay output (MA, MB) function selection is for SPDT-contact relay output (allocated in
C026).
•You can select NO- or NC-contact output for each output terminal with C031 or C036.
