10-3-2 Encoder Settings
Speed feedback card selections: See Chapter 7 Speed Feedback Card Selection. Delta provides
three types of PG cards, including EMED-PGABD-2, EMED-PGHSD-3, and EMED-PGHSD-4.

 When you set Pr.10-02 to 3, 4 or 5, you can set Pr.10-00 only to 0, 1 or 2, and you cannot
use 3, 4, 5 and 6.
 When you set Pr.10-
00 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.10-
00 to 4 or 6, wait for two seconds after applying the power before
executing the RUN command.
 When you set Pr.10-00 to 5, you must set Pr.08-09 to 360.
 Detection of the magnetic pole:
(1) 1 or 5: The AC motor 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 AC motor drive detects the position of the magnetic pole with the UVW encoder
signal.
(3) 3: The AC motor drive detects the position of the magnetic pole with the sine encoder
signal.
(4) 4 or 6: The AC motor drive detects the position of the magnetic pole with the
communication encoder signal.

Static: Brake engaged, no motor running. Dynamic: Brake released, motor rotates less than one revolution.
Rolling: Brake released, motor rotates more than one revolution.
