Servomotor Current Detection Offset Manual Adjustment (Fn00F)
•
This function manually adjusts the Servomotor current detection offset.
•
Adjust the U-phase and V-phase offsets alternately while balancing each separately.
•
When performing adjustments, rotate the Servomotor at 100 r/min. without connecting the mechani-
cal system to the Servomotor shaft (i.e., make sure there is no load), and perform the adjustments
while monitoring the waveform of the analog monitor output’s torque command monitor (current moni-
tor).
•
The Servomotor current detection offset setting range is --512 to 511.
