10 Speed Feedback Control Parameters
In this parameter group, ASR stands for Adjust Speed Regulator and PG stands for Pulse Generator.
Encoder Type Selection
Settings
 When using PG expansion card EMC-PG01L or EMC-PG01O, set Pr.10-00=1. These
expansion cards are applicable for induction motor (IM) only.
 When using EMC-PG01U, set Pr. 10-00=2 (Delta encoder), and make sure SW1 is switched to
D (Delta type). If the setting for Pr. 10-00, Pr. 10-01 and Pr. 10-02 has changed, please turn off
the drive's power and reboot to prevent permanent magnetic motor (PM) stall. This mode is
recommended to use for PM.
 When using EMC-PG01U, set Pr. 10-00=4 (Standard ABZ/UVW Encoder), and make sure SW1
is switched to S (Standard Type). This mode is applicable for both IM and PM.
 When using EMC-PG01R, set Pr. 10-00=3, and set Pr. 10-01 to 1024 ppr, then set Pr. 10-30
after verifying the pole numbers of the resolver.
 When using MI8 single-phase pulse input as frequency command, the Pr. 10-02 must set to"5:
Single-phase input". The drive calculates the MI8 single-phase pulse input speed when the
control modes are VF, VFPG, SVC, IM/PM FOC Sensorless and IM/PM TQC Sensorless. If you
use the MI8 single-phase pulse input for speed feedback in closed-loop control, you can only
use it in VFPG closed-loop control mode.
Encoder Pulses per Revolution
Settings
 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 magnetic
pole origin detection error for the PM in closed-loop control. When using the PM, you must
perform the pole zero point detection (Pr.05-00 = 4) again if you modify the content of this
parameter.
0: Disabled
1: ABZ
2: ABZ (Delta encoder for Delta Servo motor)
3: Resolver
4: ABZ / UVW
5: MI8 single phase pulse input
1–20000
 This parameter can be set during operation.
