5 Operation5.9.2 Absolute Data Request Signal (/SEN)5-605.9.2 Absolute Data Request Signal (/SEN)The absolute data request signal (/SEN) must be input to obtain absolute data as an output from the SERVO-PACK.The following table describes the SEN signal.Note: The SEN signal must be allocated. It can be allocated to a terminal with Pn515.0. For details, refer to 3.3.1 InputSignal AllocationsThe SEN signal is input at the following timing.∗ Turn OFF the SEN signal to turn OFF the control power supply.For the details of the absolute data reception sequence, refer to 5.9.5 Absolute Data Reception Sequence.Type Signal Name ConnectorPin Number Setting MeaningInput /SEN Must be allocated ON (closed) The host controller sends a request tothe SERVOPACK for the absolute data.OFF (open) Disabled• Maintain ON (closed) for at least 1.3 seconds when the SEN signal is turned OFF andthen ON, as shown in the figure below.• SEN Signal cannot be OFF while the servomotor power is ON.SERVOPACK controlpower supply 5 seconds max.ONOFFOFFON (Normal status)OFF ONRotational serial data(Phase A)(Phase B) (Phase B)Approx. 560 ms max.The servomotor will not be turned ON even if /S-ON is turned ON during this interval.ALM signal OFF(Alarm status)SEN signalPAOPBOServomotor powerUndefinedUndefined(Phase A)OFFOFFOFFOFF*ONIncrementalpulsesIncrementalpulsesInitial incrementalpulsesInitial incrementalpulsesAna-logOFF ON (closed)1.3 s min.OFF ON15 ms min.SEN signal
