TSH Posts: 73 Rating: (2)	Hello The motor is not suitable for 611U, the main reason for this is the motor is for use with 610 drives with an output voltage of 300V. The 611 system operates at 430V. Regards

TSH Posts: 73 Rating: (2)	Hello again Apologies for the last post,a 1FT5 motorwas indeed available for the higer voltage 611 drive. I cannot see any reference to this motor type in the 611U documentation, I believe this is due to the feedback type. The 1FT5 uses hall effect switches for the rotor position and a tacho for speed. The 611U uses encoders\resolvers. I will try to confirm this after the weekend and post on here. Regards

Dave Posts: 271 Rating: (27)	Hello Pudur, SimoCom U software is used for commissioning the Simodrive 611U control units. 611U is suitable for Siemens servomotors 1FK6, 1FK7, 1FT6 as well as other spindle motors, etc. The 1FT5 motors were designed for use with Simodrive 611A control units only!!! The 1FT5 motors require a trapezoidal output drive and uses Hall effect switches for commutating the motor. The newer AC servomotors all are designed for Sinusoidal output drives and Sine encoders with C / D encoder tracks for commutation purposes. Hope this helps...

Was the motor running from a 611 or 611A controller card? Or was it running from a 610 drive? You may be able to rotor id the rotor to get commutation information, but not with the typical built on encoder. Do you have a second encoder on the motor, or just the original ROD320? It is not likely to be worth your time to attempt to get it to work on 611U. Field replaceability is the problem, each of the encoder zero marks can be located differently on the 1FT5 motors (hall switches were used for commutation). Each motor will have a different commutation offset. If you read the documentation, there is some discussion about configuring the angular encoder interface as input and using a TTL signal encoder with a spindle motor. But there is no discussion about using a TTL encoder with a servo motor under 611U. It would be handy if we could use a ttl encoder, and run continously from a rotor ID (and then ignore the zero from the ttl encoder for commutation offset), then it would be feasible to do what you want. The bandwidth would be far lower that we are used to from the 1ft6 and newer motors, but for retrofits...Imagine saving the customer a lot of money on new motors, and not having to provide mounting adaptors. Perhaps a sensor module for sinamics would be handy for such things? Is there a possiblity in Simodrive other than the correct controller card? I think not at this time.
