the motor.
Fault reaction active
Fault
: Drive with fault. Disabled function, without power being applied to the motor.
NOTE!
The frequency inverter CFW-11 does not have a switch for disabling / enabling the power section
supply of the equipment. Therefore, the states described in the
implemented for a matter of compatibility with the described state machine; however the power section
supply remains active even in these states.
Description of the transitions:
Transition 0: The drive is switched on and the initialization procedure starts. The power section supply of the
drive is active.
Transition 1: Initialization completed (automatic).
