This displays the position loop gain.
Feedrate (mm/s)
Position loop gain :
Tracking delay error (mm)
The error of the actual machine position to the command position is called droop. This error is
proportional to command speed value.
This displays the actual rotation speed of motor.
This displays the motor load.
This displays the motor current command in terms of continuous current during stalling.An
absolute value of the current command peak value sampled after the power ON is displayed.
This displays the motor current command in terms of continuous current during stalling.An
absolute value of the current command peak value sampled in most recent 2 seconds is
displayed.
This displays the FB value of the motor current in terms of continuous current during stalling.An
absolute value of the current FB peak value sampled in most recent 2 seconds is displayed.
This is the data used to monitor the motor overload.
This is the data used to monitor the resistance overload state when the resistance regenerative
power supply is connected.
This displays the estimated disturbance torque in terms of stall rated torque when the
disturbance observer is valid.
This displays the estimated disturbance torque in terms of stall rated torque when the collision
detection function is adjusted.An absolute value of the estimated disturbance torque peak value
sampled in most recent 2 seconds is displayed.
This displays the estimated load inertia ratio when the collision detection function is adjusted.
This displays the thermistor temperature.
This displays the current operation frequency of the adaptive filter.
This displays the current filter depth of the adaptive filter.
This displays the 7-segment LED of the driver.
This displays the alarms and warnings other than the LED display.
This displays the position within one rotation of the encoder detector. The position is displayed
within one rotation in the range of "0" to "RNG (movement units) × 1000" using the grid point
value as "0".
