About MR Configurator2
Using MR Configurator2 can confirm if the parameter setting is normal or if the servo motor and the load-side encoder operate
properly.
This section explains the fully closed diagnosis screen.
Click "Monitor start" to constantly read the monitor display items from the servo amplifier.
Then, click "Monitor stop" to stop reading.Click "Parameter read" to read the parameter items from the servo amplifier, and
then click "Parameter write" to write them.
Symbol Name Explanation Unit
a) Motor-side cumu. feedback
pulses
(after gear) Feedback pulses from the servo motor encoder are counted and displayed. (load-side encoder unit)
When the set value exceeds 999999999, it starts with 0.
Click "Clear" to reset the value to 0.
The "-" symbol is indicated for reverse. pulse
b) Motor side droop pulses Droop pulses of the deviation counter between a servo motor-side position and a command are
displayed.
The "-" symbol is indicated for reverse. pulse
c) Cumu. Com. pulses Position command input pulses are counted and displayed.
Click "Clear" to reset the value to 0.
The "-" symbol is indicated for reverse command. pulse
d) Load side cumu. feedback
pulses Feedback pulses from the load-side encoder are counted and displayed.
When the set value exceeds 999999999, it starts with 0.
Click "Clear" to reset the value to 0.
The "-" symbol is indicated for reverse. pulse
e) Load side droop pulses Droop pulses of the deviation counter between a load-side position and a command are displayed.
The "-" symbol is indicated for reverse. pulse
f) Motor side cumu. feedback
pulses
(before gear) Feedback pulses from the servo motor encoder are counted and displayed. (Servo motor encoder unit)
When the set value exceeds 999999999, it starts with 0.
Click "Clear" to reset the value to 0.
The "-" symbol is indicated for reverse. pulse
g) Encoder information The load-side encoder information is displayed.
The display contents differ depending on the load-side encoder type.
• ID: The ID No. of the load-side encoder is displayed.
• Data 1: For the incremental type linear encoder, the counter from powering on is displayed. For the
absolute position type linear encoder, the 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.
