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 .

Spindle 25 OSP orientation Orientation speed is set. SW5 should be set in the o mark side.

In EMG, in-Position 0: It seems I found a typo or two in the charts that caused me great confusion. In additon, the fs signal contacts FA-FC are open. Example To change the data to 2 6 4 0enter [Tj[T][T]! I’ll hopefully have it running perfect this time tomorrow.

Gear 1 1 Continued on the next page. However, while the equipment is linked with the NC through the bus, the torque limit signal is separated from the indexing input signal. Freqrok Greg for all the information and diagonising the problem. Note When changing parameters, it is necessary to change those on the parameter list at the same time.

I 0 – 39tdeg. Set to idjust orientation for the respective rear. See Appendix 3 2.

The sections that follow describe how to replace the fuses, thermal protectors, amplifier cooling fan, printed circuit boards, and motor cooling fan and how to check the transistor module and diode stack. I ordered new ones and got them today. Check that it rotates for 10 turns until it comes to the hole bottom and returns to the start position. Terms and conditions apply. Sets the rotation direction of the position loop detector. When decreasing PG2, freqqrol b approaches point c.


NC through the bus is connector. In the position loop state, on the NC screen Acceleration this parameter setting is invalid. I increased it to and I can see that it takes a slight bit longer to reach the programmed speed.

Thanks Greg, So I won’t worrie about the speed difference. In the position 1: Is this idea a bit crazy, like wishfull thinking? The external wiring Visually check the external wir- is incorrect or broken ing. See Appendix 6 l are not placed in the OFF position. That’s weird the Malaysian-Ebay dude sold you used transistors. I insulated the cables that connect to the spindle drive as I did before so I could turn on the power to keep the batteries charged and it’s an old screen so I like to power it on for an hour a day.

Item Cause Check Remedy The detector magne- o Rotate the motor in the man- 0 Readjust the related cont- sensor or encoder is ner that it does not per- rols by referencing the defective. A It is checked when the power of the controller is turned on. When one screen is selected, the cursor appears at the right end of the first 1 in the setting area.

Note If the spindle hunts when the motor is stopped by the orientation operation, the selection of the mounting direction of the orientation detector is inverted. Fixed parameter being set when E2ROM is initially set.

The signal cable is not 0 Visually check that the o Correctly shield the signal correclty shielded. Thanks for the help Guys Hi guys, The story so far Check your electrical manual.

I built-in encoder so that the output signal is in the In an open loop state, input specified level. The power cable into the machine had a wire broken. Note To distinguish between a fault of the mechanical portion including the motor and that of the amplifier including the speed reference, take the following procedure.

Increments a value on the display area. The motor over- shoots in speed. Not much longer but at least it might be a bit easier on the drive.

PIN2 should be set at the same When the equipment is linked to the time. Because the contents of the parameters just depend on the machine to be used, refer to the parameter list provided by the machine manufacturer. The stop position is set within deg.

In the adjustment using the following flowchart, generally, a gear where the spindle speed is high tends to overrun, so it should be adjusted first. They will help you contact with Service Department of Mitsubishi Electric. So I found parameter SP19 and like you said Greg it was set to In stock, immediate shipping. Now you can access meau. The following figure exemplifies a waveform of phase A.
