Deviation Range Of Pid Feedback Signal Error; Pg Pulse Range; Pg Input - Delta VFD-B Series Manual

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

Settings
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

Settings
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.
