rial Operation (Checking Linear Servomotor Operation)
5.3.2 Hall Sensor Selection
(1) Linear Servomotor with Hall Sensor
For a linear servomotor with hall sensor, use the factory setting: Pn080.0 = 0
(2) Linear Servomotor without Hall Sensor
For a linear servomotor without hall sensor, select Disables selection for the parame-
ter Pn080.0. 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 OFF
the power supply and then ON to enable new setting.
When Pn080.0 = 0 is set without connecting a hall sensor, the alarm A.C21 (Hall
Sensor Error) will occur when the power supply is turned ON.
5.3.3 Motor Phase Selection
Check the following feedback signals to the SERVOPACK, and set the motor phase
sequence 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 Scale
1.
Turn ON the control power to the SERVOPACK and set to servo OFF
status.
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, and
check whether the correct number of feedback pulses is returned.

1. Before checking the feedback signals, be sure to set Pn000.0 to 0
(linear scale counting-up (phase-A advance) direction as forward
direction).
2. Be sure to check the feedback signals before operating the linear
servomotor. If the linear servomotor is operated without checking
the feedback signals, the linear servomotor may not run, or over-
run may occur.
