10 - 12
a ASR (Auto Speed Regulation) control (with PG only) (P) Unit: 0.1
Settings 0.0 to 10.0 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.
10 - 13
a 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).
