Mitsubishi Electronics FR-S500 instruction manual Load pattern selection Pr, 100%

Explanation of functions (parameters)

2.3.9Load pattern selection (Pr. 14 )

You can select the optimum output characteristic (V/F characteristic) for the application and load characteristics.

	Pr.14=0		Pr.14=1		Pr.14=2
For constant-torque		For variable-torque		For lift
loads		loads
(e.g. conveyor, cart)		(Fan, pump)

Pr.14=3

For lift

(Factory setting)	Boost for forward rotation Boost for forward rotation
	...Pr. 0 (Pr.46) setting	...0%
	Boost for reverse rotation Boost for reverse rotation
	...0%	...Pr. 0 (Pr.46) setting

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
				0: For constant-torque loads	Setting is
14	Load pattern	1	0, 1, 2, 3	1: For variable-torque loads	enabled when
	selection			2: For vertical lift loads	Pr. 30 = "1".
				3: For vertical lift loads

CAUTION

1.When automatic torque boost control is selected, this parameter setting is ignored.

2.Pr. 46 "second torque boost" is made valid when the RT signal turns on. The RT signal acts as the second function selection signal and makes the other second functions valid.
