6.6 Auto-Tuning Fault Detection
310 YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual
Digital Operator Display Error Name
Er-19 Inductance Error
Cause Possible Solutions
The induced voltage constant attempted to set a
value to E5-08 or E5-09 outside the allowable range.
Double-check the data entered to the T2- parameters, and perform Auto-Tuning again.
Digital Operator Display Error Name
Er-20 Stator Resistance Error
Cause Possible Solutions
Stator resistance tuning attempted to set a value to
E5-06 that is outside the allowable setting range.
Double-check the data entered to the T2- parameters, and perform Auto-Tuning again.
Digital Operator Display Error Name
Er-21 Z Pulse Correction Error
Cause Possible Solutions
Motor is coasting when Auto-tuning is initiated. Make sure the motor has stopped completely. Repeat Auto-Tuning.
Either the motor or the encoder on the motor is not
properly wired.
Check the wiring for the motor and the encoder. Repeat Auto-Tuning.
The direction for the encoder is set incorrectly, or the
number of pulses set for the encoder is incorrect.
Check the direction setting by F1-05 and b1-14 and number of pulses (F1-01) set for the encoder. Repeat Auto-Tuning.
Encoder is damaged. Check the signal output from the encoder attached to the motor. Replace the encoder if damaged.
PG-E3 option detected excess position error with the
ERN1387 encoder.
If other possible solutions are not successful, perform Auto-Tuning of PG-E3 encoder characteristics.
Digital Operator Display Error Name
Er-22
Initial Rotor Pole Search Error
Cause Possible Solutions
Parameters set by Initial Rotor Pole Search Tuning
were outside the acceptable range.
Switch to an absolute encoder and to the PG-F3 option card.
During normal operation, pole diversion exceeded
20 degrees.
Digital Operator Display Error Name
Er-23
Non-rotating Encoder Offset Tuning Warning
Cause Possible Solutions
Pole diversion exceeded 15 degrees three times.
Remove the ropes and conduct Rotational Auto-Tuning for Encoder Offset (T2-01 = 3).
Parameters set by Encoder Offset Tuning were
outside the acceptable range.
Digital Operator Display Error Name
Er-24 Auto-Tuning Error for PG-E3 Encoder Characteristics
Cause Possible Solutions
The signal lines between the PG-E3 option card and
encoder are disconnected at the R+ and R- terminals.
Refer to the installation manual for the PG-E3 option card for information on correct connection of signal lines.
Excessive electrical interference at the PG-E3 option
card.
The software for the PG-E3 option card does not
support the Auto-Tuning of PG-E3 encoder
characteristics.
Check the software version (PRG) for the PG-E3 option card. The software version PRG: 1102 or later support Auto-Tuning of
PG-E3 encoder characteristics.
