5. PARAMETERS

Classifi-	No.	Symbol	Name and Function	Initial	Unit	Setting
cation				Value		Range
	14	VG1	Speed loop gain 1	177	rad/s	20
			Normally this parameter setting need not be changed. Higher setting			to
			increases the response level but is liable to generate vibration and/or			5000
			noise.
			When auto tuning mode 1,2 and interpolation mode is selected, the
			result of auto tuning is automatically used.
	15	PG2	Position loop gain 2	35	rad/s	1
			Used to set the gain of the position loop.			to
			Set this parameter to increase position response to load disturbance.			1000
			Higher setting increases the response level but is liable to generate
			vibration and/or noise.
			When auto tuning mode 1 2, manual mode and interpolation mode
			is selected, the result of auto tuning is automatically used.
	16	VG2	Speed loop gain 2	817	rad/s	20
			Set this parameter when vibration occurs on machines of low			to
			rigidity or large backlash.			20000
			Higher setting increases the response level but is liable to generate
			vibration and/or noise.
			When auto tuning mode 1 2 and interpolation mode is selected, the
			result of auto tuning is automatically used.

19	FFC	Feed forward gain																0	%	0
		Used to set the feed forward gain for position control. Set "100" to																		to
		nearly zero the droop pulse value when operation is performed at																		100
		constant speed.
		Note that sudden acceleration/deceleration will increase overshoot.
		As a guideline, when you set the feed forward gain for 100%, set the
		acceleration/deceleration time constant to/from the rated speed for 1s
		or longer.
