About MR Configurator2
With MR Configurator2, the servo parameters can be checked if set correctly, and the servo motor and the load-side encoder
can be checked if operated properly.
This section explains the Linear Diagnosis screen.
Symbol Name Explanation Unit
(1) Cumulative feedback pulses Feedback pulses from the linear encoder are counted and displayed.
The displayed value returns to "0" when "999999999" is exceeded.
Click "Clear" to reset the value to "0".
In reverse rotation, the value is negative.
pulse
(2) Droop pulse Droop pulses of the deviation counter between a linear servo motor-side position and a command
are displayed.
In reverse rotation, the value is negative.
pulse
(3) Cumulative command pulses Position command input pulses are counted and displayed.
Click "Clear" to reset the value to "0".
Under reverse command, the value is negative.
pulse
(4) Encoder information The linear encoder information is displayed.
The display contents differ depending on the linear encoder type.
• ID: The ID No. of the linear encoder is displayed.
• Data 1: For an incremental type linear encoder, the counter from powering on is displayed. For
an absolute position type linear encoder, absolute position data is displayed.
• Data 2: For the incremental type linear encoder, the distance (number of pulses) from the
reference mark (Z-phase) is displayed. For the absolute position type linear encoder, "00000000"
is displayed.
(5) Polarity For the address increasing direction in the linear servo motor positive direction, "+" is displayed,
and for the address decreasing direction in the linear servo motor negative direction, "-" is
displayed.
(6) Z-phase pass status The Z-phase pass status of the linear encoder is displayed.
(7) Parameter Setting
(Resolution setting)
The servo parameters for the resolution of the linear encoder ([Pr. PL02] and [Pr. PL03]) can be
displayed and set.

(8) Parameter Setting
(Homing stop interval)
The servo parameter for the homing can be displayed and set.
(9) Parameter Setting
(Linear encoder magnetic
pole detection)
The servo parameter for the magnetic pole detection can be displayed and set.
