My customer have a Siemens motor nr: 1PH7 107-xxFxx-x The encoder on this motor is of the type HTL-signal, 15VDC.
Goals and Symptoms
My customer has a Siemens motor nr: 1PH7 107-xxFxx-x The encoder on this motor is of the type HTL-signal, 15VDC. Do we have any encoder card that supports this kind of encoder "HTL signal" for the ATV71?
Causes and Fixes
The HTL is a type of Push Pull, then VW3A3405 or 06, or 07 option boards depend the alimentation, can work without any problem on the HTL encoder. So be careful you have to verify the current maxi of your encoder in accordance with 175ma maximum up to 15V and 100ma up to 24V. Or you can add an external alimentation.
In the ATV71 catalog the low level is < 1,5V, not compatible with HTL but this value is false, in reality, we guarantee a low level <3V, 100% compatible with HTL technology <2,8V.
