Mitsubishi FR - S500 instruction manual Load pattern selection, Range

2.3.9 Load pattern selection

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	Pr.14=3
For constant-torque	For variable-torque	For lift	For lift
loads	loads
(e.g. conveyor, cart)	(Fan, pump)

100%	100%	100%		Forward	100%		Reverse
Output voltage	Output voltage	Output	voltage	rotation	Output	voltage	rotation
		Pr.0		Reverse	Pr.0		Forward
		Pr.46		rotation	Pr.46		rotation
	Base frequency						Base frequency
		Base frequency		Base frequency
Output frequency (Hz)		Output frequency (Hz)		Output frequency (Hz)			Output frequency (Hz)

				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	0	0, 1, 2,		1: For variable-torque loads		enabled
	selection		3		2: For vertical lift loads		when Pr. 30
					3: For vertical lift loads		= "1".

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.
