Group 20 Speed Control Parameters
20- 00 ASR gain 1
Range
【0.00~250.00】
20- 01 ASR integral time 1
Range 【0.001~10.000】Sec
20- 02 ASR gain 2
Range 【0.00~250.00】
20- 03 ASR integral time 2
Range 【0.001~10.000】Sec
20- 04 ASR integral time limit
Range 【0~300】%
20- 07 Selection of acceleration and deceleration of P/PI
Range
【0】: PI speed control will be enabled only in constant speed.
For the speed acceleration and deceleration, only use P control.
【1】: Speed control is enabled either in acceleration or deceleration.
20- 08 ASR delay time
Range 【0.000~0.500 】Sec
20- 09 Speed Observer Proportional(P) Gain1
Range 【0.00~2.55】
20- 10 Speed Observer Integral(I) Time 1
Range 【0.01~10.00】Sec
20- 11 Speed Observer Proportional(P) Gain2
Range 【0.00~2.55】
20- 12 Speed Observer Integral(I) Time 2
Range 【0.01~10.00】Sec
20- 13 Low-pass filter Time constant of speed feedback 1
Range 【1~1000】mSec
20- 14 Low-pass filter Time constant of speed feedback 2
Range 【1~1000】mSec
20- 15 ASR gain change frequency 1
Range 【0.0~599.0】Hz
20- 16 ASR gain change frequency 2
Range 【0.0~599.0】Hz
20- 17 Torque compensation gain at low speed
Range 【0.00~2.50】
20- 18 Torque compensation gain at high speed
Range 【-10~10】%
20-33 Detection Level at Constant Speed
Range 【0.1~5.0】%
Parameter 20-33 is used when 20-07 is set to 0 and frequency command source is set to analog
input mode. Analog input signal, owing to the noise, will cause the system to determine the
operation does not reach the constant speed so the problem may occur. Thus, adjust parameter
20-33 to avoid this situation occurring.
