SIMODRIVE base line A Start-Up
This drive variant is intended for applications for which highest encoder
resolution is not a primary concern. The control has been specially
designed for use with sine-commutated 1FK servomotors.
The resolver encoder system integrated in the motor supplies the signals
required by the control system, such as motor rotor position and actual
speed, as well as an incremental shaft encoder interface with TTL
signals for external processing.
