Note
The actually achievable system quality with regard to speed or positioning
accuracy depends primarily on the quality of the used encoders and other
influencing factors, such as:
S
S
In practice, the previously mentioned effects mean the quality that can be
achieved in a real system is significantly lower than the theoretically achievable
quality.

3 Motor Selection, Position/Speed Sensing
Encoder with TTL signal
For the speed control of induction motors with SIMODRIVE 611 universal
HRS control units, sin/cos 1 Vpp variant, TTL encoders can be connected
and evaluated.
The limit frequency f can be as high as 420 kHz.
