Operating sequence
• Starting Sequence: Motor is stopped
and ready to start → START command
(Start 1) received → Internal CCA contact closed
and remain closed → Feedback received
• Stopping Sequence: Motor is running →
STOP command received → Internal CCA
contact open → Feedback received
Contactor feedback and current feedback
are both used for verification of the mo-
tor status. Any unexpected feedback re-
sults in alarm or fault.
Contactor feedback can be disabled
through parameter. Current feedback r is
always on the background to ensure the
completion of an expected operation
sequence. The feedback time is adjustable.
