Delta VFD-B - ASR (Auto Speed Regulation) Control (with PG Only) (I); Speed Control Output Frequency Limit; Sample Time for Refreshing the Content of 210 DH and 210 EH; Speed Control Diagram

Chapter 5 Parameters|VFD-B Series
5-100 Revision July 2008, BE16, SW V4.08 & V5.00
10 - 13  ASR (Auto Speed Regulation) control (with PG only) (I) Unit: 0.01
Settings 0.00 to 100.00 Factory Setting: 1.00
0.00 disable
 This parameter specifies Integral control and associated gain (I), and is used for speed control
with PG (encoder) feedback.
NOTE
The parameter can be set during operation for easy tuning.
10 - 14 Speed Control Output Frequency Limit Unit: 0.01
Settings 0.00 to 100.00 Hz Factory Setting: 10.00
 This parameter limits the amount of correction by the PI control on the output frequency when
controlling speed via PG (encoder) feedback. It can limit the maximum output frequency.
10 - 15
Sample time for refreshing the content of 210DH and
210EH
Settings 0.01~1.00 seconds Factory Setting: 0.10
 When the signal source of feedback control is PG (encoder) and it needs to read the pulse
numbers from communication, this parameter can be used to set the refresh time of two
communication addresses (210D and 210E).
