Goals and Symptoms
My customer have 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 support 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 board depend the alimentation, can work without any problem on the HTL encoder. So be carreful you have to verrify the current consomation of your encoder in accordance to 175ma maximum up to 15V and 100ma up to 24V. Or you can add a external alimentation.
In the ATV71 catalogue 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 technologie <2,8V.
