!WARNING
A revision AAAA MX2 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 Inverter revi-
sion.
4-6-2 Operating the Motor
Step 8 Set A001=3 and A002=3 so that the Inverter can be controlled using the Mod-
bus registers.
Step 9 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.
Step 10 Change d001 to the desired frequency (E.g. 1000 for 10.00 Hz)
Table 75 Flex Mode Output Area with Motor Running Forward
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.

Step 11 Set Dir to reverse the direction of the motor. The motor decelerates, stops and
then accelerates in the opposite direction. The FA1 bit clears as soon as the
reference frequency is changed. When the motor starts reversing, the Dir bit
in Coil data 1 is set. Once the new reference frequency is reached, the FA1 bit
is once again set.
Step 12 Clear the Opr bit to stop the motor. The motor decelerates and comes to a
halt.
4-6-3 Faults and Trips
User trips can be generated by setting the EXT bit in coil data 0. You must
always immediately clear the Opr bit in your PLC program when the AL bit in
Coil Data 1 (Tripping) is set by the inverter. If the Opr bit is set when the trip
condition is cleared, the Inverter will immediately start running!
