Chapter 4 Parameters

When using multi-function input terminals to switch ASR1/ASR2, the diagram will be shown as

follows.

Setting multi-function input terminal to 17

(ASR1/ASR2 switch)	ON
OFF

OFF

ASR 1		ASR 2		ASR 1
	0.1 sec		0.1 sec

10-18	ASR Primary Low Pass Filter Gain		Unit: 0.001
Control	VF	VFPG SVC FOCPG FOCPM	Factory Setting: 0.008
mode
	Settings	0.000 to 0.350 sec
It defines the filter time of the ASR command.
When setting to 1, this function is disabled.
10-19	Zero Speed Gain (P)		Unit: 0.01
Control	FOCPM		Factory Setting: 80.00
mode
	Settings	0.00 to 655.00%
When Pr.11-00 is set to Bit 7=1, Pr.10-19 is valid.
10-20	Zero Speed/ASR1 Width Adjustment		Unit: 0.01
Control	VFPG	FOCPG FOCPM	Factory Setting: 5.00
mode
	Settings	0.0 to 120.00Hz
10-21	ASR1/ASR2 Width Adjustment		Unit: 0.01
Control	VFPG	FOCPG FOCPM	Factory Setting: 5.00
mode
	Settings	0.0 to 120.00Hz

These two parameters are used to decide width of slope of ASR command during zero speed to low speed or Pr.10-17 to high speed.
