traverse function

E65818773． Caution about the use of thetraverse controlNote the following information when you use the traverse function.■ Caution about the use of a potentiometerIf an external potentiometer (analog input) is used to set the reference frequency, an error of analog inputmay occur. If such an error becomes a problem, the operation panel or the preset speed operationfunction should be used instead.You can check the reference frequency by the status monitor function (Frequency command value).■ Suspension of traverse operationTraverse operation does not work in the acceleration/deceleration period which doesn’t satisfy the startingcondition of traverse.■ Speed reach detection band ()(Output terminal function No. 6 and 7 (acceleration/deceleration completed))On completion of acceleration, an acceleration/deceleration completed signal is issued in relation to thetraverse reference frequency.If a traverse permission signal is OFF during traverse operation, the acceleration/deceleration completionsignal is effective to the output frequency. The signal is OFF in the condition that the output frequency isthe outside of the frequency range set by  (speed reach detection band).. (See Fig. 2)Furthermore, the setting of  determines also the traverse operation start point. High frequencysetting of  enables to accelerate the machine while continuing traverse operation. Note that thetraverse frequency and the peak jump frequency before the output frequency reaches to the referencefrequency are different from those during normal operation, and they vary with the output frequency duringacceleration.
