Main Contactor Configuration
The sequencer normally controls the operation of the main (MA) contactor. The
contactor is picked up when the drive is powered up and only drops out when a Trip
fault exists in the drive. The contactor may also be independently controlled from an
external input.
Function input
Parameter Description
MA close req sel
Selects the Boolean variable that drives MA cont enable
req to independently control the contactor. Note: If this
input is used, the contactor MUST be picked before a run
request is sent to the drive, otherwise a trip fault, Run
before MA closed, will be issued.
If MA close req sel is set to Unused, the contactor will be
automatically driven by the sequencer.
Function output
Variable Description
MA cont enable req Request from sequencer to pick-up or drop out the main
contactor.
MA cont enable stat
Status to indicate to the sequencer that the main contactor
has been picked-up (dropped-out).
MA close command
Internal command to the contactor hardware to pick-up or
drop out the contactor.
MA contactor closed Actual feedback from the contactor indicating that the
contactor has been picked-up or dropped out. If
connected, then MA contactor fbk must be set to True. If
the feedback is not connected, then the contactor
sequencing uses MA pickup time to indicate the contactor
status (MA cont enable stat).
Function configuration
Parameter Description
MA contactor absent
Specifies whether a contactor is absent. If this parameter
is not set correctly, the contactor sequencing will not work
properly.
MA contactor fbk Enables the sequencing logic to look at contactor feedback
to determine if the contactor status meets the request.
(See MA pickup time below.)
MA pickup time If MA contactor fbk is enabled, then this acts as a time-out
delay. If the contactor feedback hasn’t met the command
within the specified time, the drive will generate a Cont
failed to close trip fault.
If MA contactor fbk is disabled, then this acts as the
contactor simulated feedback delay, and will update the
status to match the request after the specified delay. The
maximum delay time is 2 seconds. In simulator mode, the
sequencer ignores the contactor feedback even if MA
contactor fbk is enabled.
