*1 As inverter control is also performed actually, the scan time is approximately 40ms at 500 steps.
*2 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).
*3 Function to latch a device at power failure is not provided.
Therefore, select EEPROM for storage using
(D110 to D159) to hold device values.
REMARKS
•No buffer memory is available.
