5.4.4 Deviation zero
Check can be done that the motor is near the reference position.
This signal turns on when the difference (deviation) between the current command position and current feedback position is within the value
set by basic para.53.
Deviation zero signal is effective for the following control conditons:
1) In speed control, the stopped motor is in "servo lock" condition (system para. 81).
2) In position control
The signal on/off status is retained in other control mode such as torque contol.
The level of setting value of basic para. 53 has no relation with the positioning accuracy.
