Ensuring a safe and stable state
During commissioning of the converter it is essential to ensure that the system is in a safe
and stable state, as some commissioning processes have the potential to start the motor.
Therefore it is important to secure any loads and ensure that should the motor start, no
potentially dangerous conditions exist.
The converter will stop if the IOP-2 is removed when in Hand mode
When the IOP-2 is in Hand mode, that is, when the command source is switched to Hand
and all OFF and RUN commands are given via the IOP-2 buttons.
When in the Hand mode, if the IOP-2 is removed from the converter, the converter will stop
within a few seconds of the IOP-2 being removed.
Before removing the IOP-2, ensure that the IOP-2 is placed in AUTO mode and receiving
its command source from the PLC.
