10 Speed Feedback Control Parameters

This parameter can be set during operation.
In this parameter group, ASR is the abbreviation for Adjust Speed Regulator and PG is the
abbreviation for Pulse Generator.
Encoder Type Selection
Factory Setting: 0
Settings 0: Disable
1: ABZ
2: ABZ (Delta encoder for PM motor)
3: Resolver (Standard encoder for PM motor)
4: ABZ/UVW (Standard encoder for PM motor)
5: MI8 single phase pulse input
 For PG extension card EMC-PG01L and EMC-PG01O, set Pr.10-00=1. These extension cards
are for IM motor only.
 For EMC-PG01U, when setting Pr.10-00=2 (Delta encoder) make sure SW1 is switched to D
(Delta type). If the setting for Pr.10-00, 10-01 and 10-02 has changed, please turn off the drive’s
power and reboots to prevent PM motor stall. This mode is suggested for PM motor.
 For EMC-PG01R, when setting Pr.10-00=3 please also input 1024 ppr.
 For EMC-PG01U, when setting Pr.10-00=4 (Standard ABZ/UVW Encoder) make sure SW1 is
switched to S (Standard Type). This mode is applicable for both IM and PM motor.
Encoder Pulse
Factory Setting: 600
Settings 1~20000
 A Pulse Generator (PG) or encoder is used as a sensor that provides a feedback signal of the
motor speed. This parameter defines the number of pulses for each cycle of the PG control, i.e.
the number of pulses for a cycle of A phase/B phase.
 This setting is also the encoder resolution. With the higher resolution, the speed control will be
more accurate.
 An errotic input to Pr.10-00 may result drive over current, motor stall, PM motor magnetic pole
origin detection error. If Pr.10-00 setting has changed, please trace the magnetic pole again, set
Pr.05-00=4 (static test for PM motor magnetic pole and PG origin again).
Encoder Input Type Setting
