Yaskawa Varispeed 626VM3 Help
Greetings,
I have an inverter drive that is not happy. I have an F-905 error that keeps coming up. It is a problem with a thermistor, and I have found the thermistor and found the correct resistance with a potentiometer to keep me running. Well it only worked for a little while, and i cannot find the correct resistance again. So I believe that there is more to this problem. I have checked just about everything else and it all comes down the the drive itself. This is getting way above my head, and I was wondering if anyone had some suggestions where to get this thing fixed. I found Alfa-inc. and they have been fairly reasonable, with good turn around time. Also, is there any kind of upgrade that is out there? Thank for the help in advance!

Hello everyone
I am reconditioning an old hitachi ht 25g. Variseed 626vm3c has been used to control the turret motor. I continuously get an error F-902. Since i am using encoder control, the connector 2CN is not used. Acccording to the manual, thermistor inputs have to be given to pins 8 and 9 of 2CN. I tried giving the input to those pins but the parameter V7-1 still shows temperature of -27 degree C. Apparently i somehow need to get this above -10 to get the drive to work. If anyone else has used encoder control and has been able to run the motor, please do let me know the connector and pin numbers where you connected the two thermistor wires. I just need to get the parameter V7-1 ro read something above -10 degree C.
Thank you in advance !
