28 Control circuit for contactor feeder
Contactor feeder
Contactor feeder in M10x is designed for
symmetric 3 phase load or single phase load. All
measurement, control and protection features
which are available to NR-DOL are available to
contactor feeder load.
Unlike the NR-DOL logic in which current feedback
is a built in feature, current feedback is no longer
required for motor status verification in contactor
feeder control.
* The assigned DI and PIN code may change in actual design
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 is used for verifica-
tion of the motor status. Any unex-
pected feedback results in alarm or fault.
Contactor feedback can be disabled
through parameter. The feedback time is
adjustable.
