As a result, an operation can be performed without a zero point return operation immediately afterthe power is turned ON.For details on how to set up the absolute linear scale, refer to 5 Trial Operation (Checking Linear ServomotorOperation) in the-V Series User’s Manual, Setup, Linear Motor (No.: SIEP S800000 44).Set Pn002.2 to 0 (factory setting) to use the absolute linear scale.The SEN signal is not required when using the absolute linear scale as an incremental linear scale.5.9.1 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.The SEN signal is input at the following timing.Parameter Meaning WhenEnabled ClassificationPn002n.0[Factory setting]Uses the absolute linear scale as an absolute linearscale.
