Chapter 5 Parameters|VFD-B Series

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

1 ~ 40000 (Max=20000 for 2-pole motor)

Unit: 1

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.

10 - 11 PG Input

Settings

00 Disable PG

01 Single phase

02 Forward / Counterclockwise rotation

03 Reverse / Clockwise rotation

Factory Setting: 00

The relationship between the motor rotation and PG input is illustrated below:

10 - 12 ASR (Auto Speed Regulation) control (with PG only) (P)

Settings

0.0 to 10.0

Unit: 0.1

Factory Setting: 1.0

This parameter specifies Proportional control and associated gain (P), and is used for speed

control with PG (encoder) feedback.

NOTE

The parameter can be set during operation for easy tuning.
