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 overload of motor and drive unit.
This is the data used to monitor the resistance overload state when the resistance re-
generative 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 current operation frequency of the adaptive filter.
This displays the current filter depth of the adaptive filter.
While Real-time tuning 1 is valid, the currently applied speed control gain is displayed
with the magnification for the setting value of speed loop gain 1 (parameter "#2205
SP005 VGN1").
This displays the 7-segment LED of the driver.
This displays the alarms and warnings other than the LED display (displayed on drive
unit side).
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".
This displays the grid space for the reference position return. (Command unit)
This displays the distance from the dog-off point to the grid point when the dog-type
reference position return is displayed. The grid mask amount is not included. (Com-
mand unit)
This displays the NC basic machine coordinate system position. (Command unit)
This displays the feedback value of the speed detector. (Command unit)
This displays the feedback position of the machine end position detector. (Command
unit)
This displays the error of the motor end FB and machine end FB.
This follows the setting and display unit (#1003 iunit).
This displays the compensation pulse amount during dual feedback control.
This follows the setting and display unit (#1003 iunit).
The remaining movement distance of one block is displayed. (Command unit)
The value of the tool compensation amount subtracted from the current position is dis-
played. (Command unit)
The amount of interrupt movement in the manual absolute OFF state is displayed.
(Command unit)
The absolute position that does not include the machine error compensation amount
is displayed. (Command unit)
This displays the current value of the synchronous error between the basic axis and
the synchronous axis during control axis synchronization between part systems, con-
trol axis superimposition, or arbitrary axis superimposition.
This displays the maximum value of the distance in which the synchronous axis ad-
vances beyond the basic axis during control axis synchronization between part sys-
tems, control axis superimposition, or arbitrary axis superimposition.
This displays the maximum value of the distance in which the synchronous axis lags
behind the basic axis during control axis synchronization between part systems, con-
trol axis superimposition, or arbitrary axis superimposition.
This displays the synchronous error width between the basic axis and the synchro-
nous axis during control axis synchronization between part systems, control axis su-
perimposition, or arbitrary axis superimposition.
