[2] Check mode of the load of Jog dial
Measurement
The load (light or heavy) on the Jog dial when it is turned can be objectively judged in this mode.
First, start "[1] Check mode of the buttons and displays."
When the TOUCH/BRAKE knob is turned to the far right, "[2] Check mode of the load of Jog dial" will begin.
When the Jog dial is rotated swiftly in this mode, the speed is measured.
Either direction, clockwise or counterclockwise, is OK.
The meaning of the numerical value displayed is as follows.
TOP SPEED : Maximum speed given that normal speed is defined as when one rotation takes 1.8 sec.
TIME : Time required for the jog dial to slow down from 3x speed to 1.5x speed.
To measure the time required for slowdown, the maximum speed must be 7 times normal speed or higher.
If the maximum speed does not reach 7.0 times normal speed, the time indication section (00M:00S 00.0F) flashes as a warning.
When the measurement is carried out several times in a row, time will be displayed as an avarage of maximum 99 times of the
measurement.
This evens out the measurement value.
Judgment result
If the measured time is within a certain range, [OK] will be
displayed in the line of the title. If not, [NG] will be displayed.
The judgment value for this is 170 ± 20 msec.
Record of a judgement
If you insert a USB memory and press the MASTER TEMPO
button, the measurement result can outputted as a CSV file
under the name "JOGLOAD_2000NXS2.C
The new data is added whenever the MASTER TEMPO
