It is advisable to change the thermistor, but as it goes inside the motor, the other option is with a 100 ohm resistor
Hello,
I am having a Yaskawa Spindle Drive Varispeed 626VM3 is having Alarm F-E04. It means Motor Code Setting Error. I am unable to resolve it. If you know any solution please tell me. Can you please tell which parameter of this drive is responsible for Drive Capacity Code.

I have the same problem
but what you mean by a power supply problem ?!
is it control power supply
or power interface card power (fuses & transformers are working properly )
and starting the drive (not installed in the machine) by supplying 3 phase 220 VAC with an electrical contactor and contected to an encoder to avoid encoder problem !!
power supply control output of the power supply as follow at 24 CN
1. Ground
2. Ground
3. 5 VDC
4. 5 VDC
5. 15 VDC
6. -15 VDC
7. 24 VDC
8. 5 VDC
Any suggestions !!!!???
can you please forward the user manual to my mail id : macrocontrolshyd@gmail.com
i have a problem with F-A00 error on Varispeed626VM? can anyone help me?
Hello
I have 1 hitachi seicos 10L cnc lathe
The spindle adopts Yaskawa 626VM3 18.5KW inverter.
F_C41 error is reported.
Please ask what is the error, and how to fix it.
Thank you!
Hello, I have the F-905 error. Would someone be able to tell me where the thermistor is? I have found one thermistor labeled th2 on the board, but adding resistor here made no difference. My display unit was showing -30c before and after. perhaps I have the wrong one, or maybe something else going on. here is the picture of the v-13 output showing the temp reading and an arrow to the thermistor I was playing with . Thanks in advance.

Thanks, I realize now that I was not looking at the right heatsink. I removed the unit from the machine and there is a large heatsink with a fan at the back. Its sunk into the machine cabinet and was not visible.
Now that I am looking at the correct heatsink I hope I can locate the thermistor.
I'm having they exact same issue on a Tree mill. I have a potentiometer from an AC motor. how would you wire that to the thermistor
Mine is now fixed. Measure your thermistor before doing anything. Mine turned out to be working. It should show some resistance. Blast it with cold air from a computer cleaner can, it should change.
In my case it ended up being a bad trace on the board going from the the ribbon connector to a capacitor on the board. Had to take it to a repair shop and it took the technician some time to find the fault. He ran a wire between the 2 points.hope this info helps others.
