What 1686 means
POS.DEVIATION SATURATING ERROR (SV) p. 151
Common causes
- Setting error p. 151
- Connection failure p. 151
- Module failure (motor) p. 151
- Servo control board failure p. 151
- Module failure (amplifier) p. 151
What to do
- Check the settings for manipulator motion condition (influence by external force, load condition). p. 151
- Check if a ground fault has not occurred in the U-, V-, and W-phase of motor power line, or short circuit has not occurred between these phases. p. 151
- Check the connection of motor power line. p. 151
- (1)Turn the power OFF then back ON. (2)If the alarm occurs again, replace the motor. p. 151
- (1)Turn the power OFF then back ON. (2)If the alarm occurs again, replace controller. Save the CMOS.BIN before replace controller to be safe. p. 151
Before you service the product, read the safety instructions in the manual p. 4.
If 1686 is still not resolved
- (1)Turn the power OFF then back ON. (2)If the alarm occurs again, replace the motor. p. 151 “(1)Turn the power OFF then back ON. (2)If the alarm occurs again, replace the motor.”
