4. SERVO FUNCTION DETAILS B-65150E/04
− 228 −
<4> Start the "SD" software, and make the following setting.
DOS prompt > SD INIT[Enter]
o (Origin of position)
F9 (System setting)
0 (CH0)
2[Enter] (TCMD)
1.0 [Enter] (1.0A)
1 (CH1)
2[Enter] (TCMD)
40[Enter] (Maximum current for servo amplifier to be used)
F10 (Return to main menu.)
(Ctrl)T (XTYT mode selected)
F2 (Data number)
9000 [Enter] (Number of data items to be measured)
NOTE) This description uses the 3000B as an example. It differs
from other models only in the current rating of the servo
amplifier.
<5> When determining the correction parameters, set the velocity gain
to a rather low value.
<6> Cause the linear motor to reciprocate at F1200 (mm/min), using a
stroke of over 200 mm or longer.
<7> Pressing the F1 key (to start measurement) at regular speed
displays the data shown below. (Check that the activating phase
angle-based sine waveform changes from negative to positive at
three points or more.)
CAUTION
Measurement direction varies with the setting of the
direction-of-movement parameter.
When the setting is 111: Measurement is
performed during forward movement.
When the setting is −111: Measurement is
performed during backward movement.
Measurement in the wrong direction hinders correct
calculation of the correction parameter.
