GENERAL. Usage of Maintenance Manual. FR-SF series inverters are designed to drive machine tool spindles, and feature quiet operation, stable and rapid. Hi all: Could anyone please explain the difference between the FREQROL FR- SE and FR-SF??? To me they sound the same I thank you for. Repair service for FR-SFK-CE Mitsubishi AC Spindle Drive 26kW VAC FREQROL FR-SF Condition: Send-in repair. Free evaluation. 6 Months warranty .

Please advise me with above mentioned information. After it is turned on, the parameters are validated.

Mitsubishi FR-SF

Is it a matter of changing parameters at the NC screen freqtol is it changing parameters at the spindle controller? At the time, correct the selection using the parameter ORS2 bit 8.

Position loop Creqrol after orientation 1: Lights when the power is turned on or the machine is reset. See the right-hand figure. Phase U See Appendixes 6 l and 9 l. Fixed on the heat radiation fin with screws. When the orientation time becomes long because the time period on which the spindle rotates at a creep speed point b to c is long, decrease PGl or in- crease OSP in the manner that the spindle does not overrun when it stops.


See the note of the alarm No.

Good Result guys, Thanks a lot, Mark. Note 1 If a multiple of parameters is defective, check and correct the parameters in accordance with the parameter error Nos. For instructions for setting parameters, see Reference 1. It should be set in the range from 1 time to 2 times H to H. I replaced all the 6 base Rf as was recomended by Greg. English Choose a language for shopping.

In addition, with the parameters obtained by the adjustment, check that the spindle correctly rotates at each speed and by each gear.

The only other thing I noticed was that the Spindle drive is displaying a different speed to the machine. When decreasing PG2, point b approaches point c.
