Application Precautions
!WARNING
!Caution
xii
Failure to observe these precautions could lead to serious or possibly fatal
injury. Always read these precautions.
• Check any user program in the system that acts as a PROFIBUS master
before actually running it. Not checking the program may result in unex-
pected operation.
• A revision AAAA MX2-A@ Inverter allows the motor to run immediately if a
trip condition is reset, and at the same time, a run command is active via
PROFIBUS. For safe operation clear the run command via PROFIBUS as
soon as a trip condition is detected. Refer to section 1-1-2 Inverter Sup-
port to determine the MX2-A@ Inverter revision.
Failure to observe these precautions could lead to faulty operation of the
Option Board or the Inverter, or could damage to either of the two. Always
read these precautions.
• Check the Inverter settings for proper Inverter behaviour before actually
operating the Inverter remotely via the PROFIBUS network.
• Check the Inverter's EzSQ program and its interaction with the PROFI-
BUS master before actually running it on the Inverter. Not checking the
program may result in unexpected operation.
• Confirm that no adverse effect will occur at the moment the PROFIBUS
master stops communicating with the Inverter or at the moment the
PROFIBUS master has not yet started communicating to the Inverter.
• Confirm that no adverse effect will occur in the Inverter before force-set-
ting/force-resetting any bit in the system that acts as a PROFIBUS mas-
ter.
