The factory setting is Pn080.0 = 0 (Enables selection), so change the set-ting to Pn080.0 = 1 (Disables selection). After having changed the setting, turn OFFthe power supply and then ON to enable new setting.When Pn080.0 = 0 is set without connecting a hall sensor, the alarm A.C21 (HallSensor Error) will occur when the power supply is turned ON.5.3.3 Motor Phase SelectionCheck the following feedback signals to the SERVOPACK, and set the motor phasesequence using the parameter Pn080.1.• Check whether the signals from the linear scale are correctly received.• Check whether the forward direction and linear scale count direction are the same. Checking the Signals from the Linear Scale1. Turn ON the control power to the SERVOPACK and set to servo OFFstatus.2. Displays the monitor mode parameter Un00D (Feedback Pulse Counter)on the panel operator or digital operator.3. Move the linear servomotor from end to end of the stroke by hand, andcheck whether the correct number of feedback pulses is returned.Parameter Meaning When EnabledPn080 n.0 Enables selection [factory setting] After restartn.1 Disables selection1. Before checking the feedback signals, be sure to set Pn000.0 to 0(linear scale counting-up (phase-A advance) direction as forwarddirection).2. Be sure to check the feedback signals before operating the linearservomotor. If the linear servomotor is operated without checkingthe feedback signals, the linear servomotor may not run, or over-run may occur.
