12.1-10-2
 When Pr.10-00 = 8, PG card detects the number of rotation laps. If the application is Rotation
axis (Pr.10-60 bit 4–7, coordinate system type = 1 (Rotation axis 1) or 2 (Rotation axis 2)), the
maximum rotation number of the encoder and the overflow signal EcOF display. Therefore, for
this application, it is recommended to set Pr.10-60 bit8–11 (Encoder overflow treatment) to 2:
No warn and continue to operate.
10-01
Encoder Pulses per Revolution
Default: 600
Settings 1–65535
 This parameter sets the encoder pulses per revolution (ppr). It is a feedback control signal source
when using PG. The encoder sets the number of pulses for the motor rotating through one
rotation. The A/B phase cycle generates the pulse number.
 This setting is also the encoder resolution. The speed control is more accurate with higher
resolution.
 If you set this parameter incorrectly, it may cause motor stall, drive over-current, or a permanent
magnetic pole origin detection error for the PM in closed-loop control. When using the PM, you
must perform the magnetic pole origin detection (Pr.05-00 = 4) again if you modify the content
of this parameter.
 The hardware bandwidth of EMC-PG01L and EMC-PG01O is 300 kHz. Take a two-pole pairs IM
as example, if you choose a 1024 ppr encoder, the maximum operation frequency for closed-
loop control is 300k ÷ 1024 × 2 poles pairs = 586 kHz; in other words, one-pole pairs motor can
only work under 293 Hz and below. To work with higher frequency, you need to choose an
encoder with lower distinguish ability or enable Pr.11-00 bit11 = 1 (Switch between IMFOCPG
and IMVF modes).
 In V/F mode, if you set the parameters for number of poles, encoder and mechanical gear ratio
correctly, and set Pr.00-04 = 7, the keypad displays the motor speed (including direction) that
detected by the encoder, which could be the inspection method when an error occurs to the
FOCPG operation.
 When Pr.10-00 = 8, it only supports encoders with resolution that is smaller than 17bit. The
default for Pr.10-01 is 32768, which is only applicable for encoders with 17bit resolution. If the
encoder resolution is not 17bit, set Pr.10-01 to encoder resolution divided by 4.
For example: Encoder resolution = 16 bit, then 2
16
= 65536, 65536 ÷ 4 = 16384. Set Pr.10-01 =
16384.

Encoder Input Type Setting
Default: 0
Settings 0: Disabled
1: A / B phase pulse input, run forward if A-phase leads B-phase by 90
degrees.
