MODE – E: RING SPINNING FRAME (RSF) FUNCTION PARAMETERS
GROUP-1: RSF / PATTERN RUN PARAMETER SELECTION
Ring Spinning Frame function is used to perform spinning pattern operation. In RSF, acceleration /
deceleration is performed in a straight line till the set frequency for the next step is reached.
Up to three speed-time pattern (Tables) can be set up to a maximum of 15 steps. Each step is set at
the target frequency and time taken to reach that frequency from the previous step.
Select RSF function in E101 to perform this operation. Now, when RUN command is issued, operation
will commence from step-1 of the selected table.
After the pattern has been completed, the inverter will stop according to the selected stop mode in
A304.

If STOP command is issued during the ring spinning frame operation, inverter will stop according to
the selected stop mode in A304. When restarting the operation, it will accelerate the output frequency
as per the normal acceleration time to the frequency, where inverter was stopped. Now, it will resume
the normal RSF operation.
PR/RSF Reset: Assign 'PR/RSF Reset' function to any sequence input terminal. A stop occurs when
the PR/RSF Reset is turned ON during RSF operation. Operation is commenced from STEP-1 when
restarting the operation.
Doff-End Alarm: By setting the Doff-End alarm time (E105), the Doff-End alarm is output from the
point after completion of the final step to the point going back the set time.
The Doff-End alarm remains ON even after the pattern is completed. The Doff-End alarm is cleared
by the PR/RSF Reset.
Select the output terminal for the Doff-End alarm with the output selection (C107 to C112).
To restart the operation after the Doff-End alarm is ON, reset the Doff-End alarm using PR/RSF
Reset; otherwise it will not allow the operation to start even if the RUN command is reissued.
Hank count display (M213)
The current Hank count displays at monitor M213. The Hank count is obtained using the following
formula.
F [Hz]: Average frequency
AVG
Calculate the average frequency from the given equations considering the stop mode used.
