" instruction.
3) Two or more inverter communication instructions (IVCK, IVDR, IVRD, IVWR, IVBWR
*1
and IVMC) can be
driven for the same port at the same time.
4) Two devices are occupied respectively from the devices specified in and .
Make sure not to use such devices as to be used for other controls.
5) If a device number outside the allowable range due to indexing, etc. is specified in , the receive data
from the inverter is not stored in devices specified in . However, values set in and +1 may
be written to the inverter.
6) If any unspecified value is set in , unexpected data may be written to or read from the inverter,
and values stored in and +1 may be updated.
7) IVMC instruction reads the inverter status at the time of communication with the inverter, and stores the
read status to the device specified in . Accordingly, the status written by IVMC instruction can be
read by a next or later read instruction (IVCK or IVMC).
