InvStat C Inverter status A (Refer to Inverter Manual section B-4-2)
A revision AAAA MX2-A@ Inverter allows the motor to run immediately if a trip
condition is reset, and at the same time, Opr (Coil data 0) is set. For safe
operation clear Opr (Coil data 0) when you detect that InvStat A changes to 8.
Refer to section 1-1-2 Inverter Support to determine the MX2-A@ Inverter
revision.
Note
The operation status coil (000Fh) cannot be used in the output process area
because it is not writeable.
Set A001=3 and A002=3 so that the Inverter can be controlled using the Mod-
bus registers.
Set the Opr bit to put the Inverter in run mode. The RUN indicator on the
Inverter should light up at this point. If this is not the case, check your source
selection.
Change d001 to the desired frequency (E.g. 1000 for 10.00 Hz)

The motor accelerates until it reaches the desired frequency. Notice that the
FA1 bit is set once the inverter has reached the desired reference frequency.
