Revision 10/2005, BE13, SW V4.08 5-109

AC motor drive action when the feedback signals (analog PID feedback or PG (encoder) feedback) are
abnormal acc. to Pr.10-16.
10 - 16
Deviation Range of PID Feedback Signal Error Unit: 0.01
Settings 0.00~100.00% Factory Setting: 100.00
The base is Pr.01-00. When in PID feedback control, if | Source of PID reference target – feedback | > Pr.10-
16 and exceeds Pr.10-08 detection time, the AC drive will operate according to Pr.10-09.
10 - 10
PG Pulse Range Unit: 1
Settings 1 ~ 40000 (Max=20000 for 2-pole motor) Factory Setting: 600

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.

For PG or encoder feedback an option PG-card is needed.
