Display item Details
MAX CUR 3 (%) This displays the FB value of the motor current in terms of continuous current
during stalling.
An absolute peak value of the current FB, which was sampled within the last
two seconds, is displayed.
OVER LOAD (%) This is the data used to monitor the overload on the motor.
OVER REG (%) This is the data used to monitor the resistance load state when the
resistance regenerative power supply is connected.
AMP DISP This displays the 7-segment LED of the driver.
ALARM This displays the alarms and warnings other than the LED display (displayed
on drive unit).
EST DISTURB TORQ
(%)
This displays the estimated disturbance torque in terms of stall rated torque
when the disturbance observer is valid.
MAX DISTURB TORQ
(%)
This displays the estimated disturbance torque in terms of stall rated torque
when the collision detection function is adjusted.
An absolute peak value of the estimated disturbance torque, which was
sampled within the last two seconds, is displayed.
LOAD INERTIA R. (%) This displays the estimated load inertia ratio when the collision detection
function is adjusted.
Temperature (deg C) This displays the thermistor temperature.
AFLT FREQUENCY
(Hz)
This displays the present operation frequency of the adaptive filter.
AFLT GAIN (dB) This displays the present filter depth of the adaptive filter.
CYC CNT
(p)
This displays the position within one rotation of the encoder detector.
The position is displayed as a grid point value as "0", within one rotation in
the range of "0" to "RNG (movement units)
∗
1000".
GRDSP This displays the grid space for the reference position return. (Command
unit)
GRID This displays the distance from the dog-off point to the grid point in the
dog-type reference position return. The grid mask amount is not included.
(Command unit)
MAC POS This displays the NC basic machine coordinate system position. (Command
unit)
MOT POS This displays the feedback position of the speed detector. (Command unit)
SCA POS This displays the feedback position of the machine end position detector.
(Command unit)
FB ERROR (i) This displays the deviation between the motor end FB and the machine end
FB.
DFB COMP (i) This displays the compensation pulse amount during dual feedback control.
DIS TO GO This displays the remaining travel distance of one block. (Command unit)
POSITION(2) This displays the current position amount after the tool compensation amount
is subtracted from the amount. (Command unit)
