1.2 PLC Function Specifications
The following table indicates the program capacity and devices of the PLC function.
*1 These signals use the same terminals as used by the input and output signals given in the
common specifications of the inverter.
One point is always necessary for a sequence start (RUN/STOP).
*2 As inverter control is also performed actually, the scan time is approximately 40ms at 500 steps.
