 2: Executes the motor auto-tuning. When in the manual mode (inspection), the controller
executes upward or downward operation inspections, and then the motor auto-tunes immediately.
After auto-tuning is finished, the inspection stops outputting for ten seconds to prevent the
elevator from malfunctioning.
 Precautions for motor auto-tuning:
1. After you have set the motor auto-tuning, some faults and errors (including safety hatch
signals, gate and layer door safety hatch signals) will not be detected. Thus make sure the
motor movement (rotation) is safe before setting the motor auto-tuning.
2. Static auto-tuning does not guarantee that the motor does not move (rotate). Make sure that
no danger occurs if motor moves (rotates).
3. After you have set the motor auto-tuning, Pr.13-21 is automatically set to 0 if the drive does
not execute auto-tuning within ten seconds.
4. After you have set the motor auto-tuning, Pr.13-21 is automatically to 0 no matter whether the
auto-tuning still executes after 120 seconds or not.
 Precautions for the magnetic pole offset angle auto-tuning:
1. Motor auto-tuning should be finished before auto-tuning.
2. When Pr.13-21=1, unload before auto-tuning.
3. When Pr.13-21=3, the motor can be loaded or unloaded before auto-tuning.
4. Make sure the brake is released before auto-tuning.
5. You can use static tuning, but Pr.13-17 Bit9 must be set to 1 and works with Pr.13-22
correspondence table among encoder, PG card and auto-tuning.
6. Make sure Pr.13-24 (Encoder Input Type Setting) is correctly set. An incorrect Pr.13-24
setting would cause a wrong magnetic position, further making Pr.13-16 (PM Magnetic Pole
Offset Angle) auto-tune incorrectly.
 When Pr.13-22=5, you do not need to execute the magnetic pole offset angle auto-tuning. But
you must set Pr.13-16=360, and then power-on again.
Selection of Encoder
Settings 0–6
 When you set Pr.13-24 to 3, 4 or 5, you can set Pr.13-22 only to 0, 1 or 2, and you cannot use 3,
4, 5 and 6.
 When you set Pr.13-22 to 3, the encoder has one sine and one cosine signal for each revolution.
The signal must be: 0.75–1.2 Vpp for the amplitude with phase angle 90°±5 elec. (E.g. ERN 1185
ERN 1387)
 When you set Pr.13-22 to 4 or 6, wait for two seconds after applying the power before executing
the RUN command.
 When you set Pr.13-22 to 5, you must set Pr.13-16 to 360.
 Detection of the magnetic pole:
(1) 1 or 5: The drive outputs a short circuit to detect the position of the magnetic pole. At this
moment, the motor generates a little noise.
(2) 2: The drive detects the position of the magnetic pole with the UVW encoder signal.
(3) 3: The drive detects the position of the magnetic pole with the sine encoder signal.
(4) 4 or 6: The drive detects the position of the magnetic pole with the communication encoder
signal.
0: Disabled
1: ABZ
2: ABZ + Hall (UVW type)
3: SIN/COS + Sinusoidal (ERN1185, ERN1387)
4: SIN/COS + Endat (ECN1313, ECN413)
5: SIN/COS
6: SIN/COS + Hiperface (SRS50/60)
